Are You Susceptible To Vision Loss?

Ask Our Eye Doctor in Le Mars, Iowa, how To Prevent Vision Loss

Vision loss is more common than you may think! In fact, it’s among the most prevalent disabilities in adults and children. Knowing what puts you at risk of developing vision loss is important and can help you to be proactive about caring for your eyes.

Below, we’ll explore the most common causes of vision loss and the risk factors associated with each.

Spreading awareness and education about visual health is just one way that our eye doctors near you can help. To schedule your Comprehensive eye exam, call us today 712-546-6868.

Glaucoma

Glaucoma is a group of eye diseases caused by a buildup of pressure within the eye. Too much inner-eye pressure can damage the optic nerve and lead to vision loss.

Since symptoms don’t usually manifest in the early stages of glaucoma, getting regular eye exams is all the more crucial. Advanced or rapidly progressing glaucoma can show a variety of symptoms, such as blurred vision, headache, severe eye pain and redness, seeing halos around lights, and nausea.

Risk factors for developing glaucoma include:

  • Being 60 years or older
  • Family history of glaucoma
  • African, Asian, or Hispanic descent
  • High myopia (nearsightedness) or hyperopia (farsightedness)
  • Previous eye injury or certain eye surgeries
  • Certain medications, like corticosteroids
  • Thin corneas
  • Certain medical conditions, like diabetes, hypertension, heart disease, and sickle-cell anemia

Cataracts

Cataracts occur when the eye’s lens becomes cloudy. A healthy lens is clear and allows light to pass through it undisturbed.

Common cataract symptoms include cloudy or blurred vision, difficulty seeing at night, light sensitivity, double vision in the affected eye, and seeing colors as faded or yellowish.

Risk factors for developing cataracts include:

  • Aging
  • Diabetes
  • Hypertension
  • Smoking
  • Previous eye surgery, injury, or inflammation
  • Alcoholism
  • Extended use of corticosteroids

Age-Related Macular Degeneration (AMD)

AMD is the leading cause of severe vision loss in adults over the age of 60. It occurs when the macula (the small central portion of the retina, which is responsible for sharp, colorful, central vision) begins to wear down.

Early stages of AMD usually go unnoticed, but later stages of the disease can produce symptoms like blurred vision, dark or blurry areas in your central vision, and problems with color perception.

There’s not yet a cure for AMD, but certain treatments can help prevent vision loss.

Risk factors for developing AMD include:

  • Smoking
  • Obesity
  • Aging
  • Long-term sun exposure
  • Hypertension
  • Heart disease
  • Family history of AMD
  • Light-colored eyes
  • Farsightedness

Diabetic Retinopathy

Diabetic retinopathy (DR) is a complication of Type 1 or 2 diabetes that affects the light-sensitive tissue at the back of the eye called the retina.

Initially, diabetic retinopathy shows no symptoms but can eventually lead to blindness. As it develops, it can cause increased floaters, impaired color vision, dark spots in your visual field, and blurred vision.

Risk factors for developing diabetic retinopathy include:

  • Length of time from diabetes diagnosis — the longer you’ve had it, the higher your chances of developing visual complications
  • Uncontrolled blood sugar
  • Obesity
  • High cholesterol or blood pressure
  • Pregnancy
  • Smoking
  • African American, Hispanic, and Native American ethnicities
  • Family history of DR

So, what’s the bottom line?

Multiple factors contribute to eye disease and vision loss, and some may even be relevant to you. If you think you may be at risk for vision loss or experience any of the symptoms listed above, speak with your eye doctor in Le Mars as soon as possible. We also recommend you have your eyes thoroughly examined every 1-2 years, or as often as your eye doctor recommends. To schedule your comprehensive eye exam, call Advanced Eye Health today.

Can blindness be prevented?

When caught early, many eye diseases can be treated to halt or slow the progression of the disease and potentially prevent vision loss. The best things you can do to preserve your vision for the long term is to lead a healthy lifestyle and make sure you undergo a comprehensive eye exam every 1-2 years.

Which eye diseases are genetically inherited?

More than 350 ocular diseases have some sort of genetic component. Certain diseases, like retinitis pigmentosa and albinism, are directly inherited through chromosomal information. In other cases, a predisposition to the disease is inherited, rather than the disease itself.

Are Contact Lenses Safe For Young Children?

Here’s a question we often get at our practice: Is my child too young for contact lenses?’ This is an important question, and the answer may surprise you.

For children with myopia (nearsightedness), contact lenses can be a convenient method of vision correction. It allows kids to go about their day without having to worry about breaking or misplacing their glasses, and enables them to freely participate in sports and other physical activities.

Some children and young teens may ask their parents for contact lenses because they feel self-conscious wearing glasses. Contact lenses may even provide children with the confidence boost they need to come out of their shell. Moreover, these days, it is very popular for children to wear single-use one-day disposable soft contacts, since there is no cleaning or maintenance involved.

Some parents may deny their child’s request for contacts due to concerns about eye health and safety. There’s no reason to worry: contact lenses are just as safe for children as they are for anyone else.

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam.

Will you need medications or surgery – now or in the future? Our Le Mars eye doctor has prepared the following answers to your questions about eye disease.

At Advanced Eye Health, we provide children, teens, and patients of all ages with a wide variety of contact lenses. If you’re concerned about the safety of contacts for your child, we’ll be happy to explain and explore ways to ensure maximum safety, optimal eye health and comfort.

What Are the Risks of Having My Child Wear Contact Lenses?

Read what our patients have to say on Google Reviews

A study published in the January 2021 issue of The Journal of Ophthalmic & Physiological Optics found that kids aren’t at a higher risk of experiencing contact lens complications.

The study followed nearly 1000 children aged 8-16 over the course of 1.5-3 years to determine how contact lenses affected their eye health.

The results indicate that age doesn’t have an effect on contact lens safety. In fact, the researchers found that the risk of developing infections or other adverse reactions was less than 1% per year of wear — which is comparable to contact lens wearers of other ages.

But before you decide that contact lenses are right for your child, you may want to consider whether your child is ready to wear them. During his or her eye doctor’s appointment, the optometrist may ask about your child’s level of maturity, responsibility, and personal hygiene. Since many children are highly motivated to wear contacts, they tend to display real maturity in caring for their lenses. That said, in the initial stages, parents may need to play an active role, as their child gets used to inserting and removing the new contact lenses.

It’s important to note that just as with any other medical device, contact lenses are not risk-free. Anyone who wears contact lenses has a chance of developing eye infections or other complications with contact lenses. However, when worn and cared for according to your eye doctor’s instructions, contact lenses are low-risk and perfectly safe for children and teenagers.

So, go ahead and bring your child in for a contact lens consultation! We’ll help determine if your child is ready for contacts and answer any questions you or your child may have. To schedule your child’s contact lens fitting or eye exam, contact Advanced Eye Health in Le Mars today.

Age Related Macular Degeneration and Your Central Vision

5 Reasons To Wear Sunglasses In The Fall

A Guide to Proper Contact Lens Care

Help! My Child Doesn’t Want to Wear Glasses!

Do your kids need glasses in order to see clearly? Maybe they have a strong case of nearsightedness, perhaps they have astigmatism, or another type of refractive error. Whatever the cause, getting your kids to wear eyeglasses can be a parenting challenge.

Dr. Becky DeRuyter treats patients from all over Le Mars, Iowa with their vision correction needs. The knowledgeable, caring staff at Advanced Eye Health can help you and your kids if they’re struggling with their glasses or don’t want to wear them.

Why Won’t My Child Wear His or Her Glasses?

To help your children get the best vision possible, you first need to understand why they’re fighting with you over their glasses. It usually stems from something physical, emotional, or social, such as:

  • Wrong fit
  • Wrong prescription
  • Personal style
  • Reactions from friends

How do you know which it is? Pay close attention to the signs, from what your kids say, to how they behave, to how they interact with others.

Physical

Improper fit is a big reason why glasses could feel uncomfortable. If they slip down, itch behind the ears, or put pressure on the bridge of the nose, it can explain why a child wouldn’t like to wear them.

If there’s been a big change to their prescription, they may need time to get used to it. If they were given the wrong prescription, they may be straining their eyes, getting headaches, or having eye fatigue. An incorrect prescription can make wearing glasses painful or awkward. It doesn’t correct their vision, either, so they’ll still see blurry images. When this happens, your eye doctor can check the prescription and make an adjustment.

Emotional

Your kids at home aren’t the same as your kids in school, on the sports field, or with their friends. They may be afraid of being made fun of in school, or they may not want the sudden attention on their appearance. These feelings can be even stronger among the tween and teen set.

Social

Even young kids can feel different when they put on a pair of glasses, especially if it’s for the first time. Feeling different or weird, in their eyes, translates to a negative experience. When wearing glasses makes them feel like the odd man out, they may not want to wear them. The last thing your child wants is to feel like a social outcast. After all, everyone wants to belong.

How We Can Help

First, bring your child in to the eye doctor for an eye exam. Our optometrist, Dr. Becky DeRuyter, will check to make sure that your child has the right prescription and that any vision problems are being corrected. Next, we’ll take a look at the glasses and place them on your child’s face to determine if they’ve got the proper fit. Our optician will take care of any adjustments that need to be made.

The Vision They Need, The Style They Want

Fashion isn’t only for adults. Your budding fashionista or trendy young stud wants to look awesome, so don’t forget about style. When your kids look great, they’ll feel great! Give them the top-quality eyewear they need without compromising on style. Your kids are a lot more likely to wear glasses when they like the way they look.

What You Can Do to Help

Encourage, stay positive, and don’t give up. Avoid telling them what you want them to wear. Let them choose for themselves. In the end, they’re the ones wearing the glasses. Making decisions is an important life skill, something they’ll need as they grow up and become more independent.

For younger children, use positive words to encourage them. Talk about how glasses are like magic, letting them see beautiful things around them. Show them how a pretty flower or a bright red truck looks with the glasses on, and how different it looks with the glasses off. For older kids, throw in a little pop culture. Tell them how trendy they’ll look by showing them pictures of celebrities who also wear glasses. You’ll also rack up some cool parent points.

At Advanced Eye Health, we have the experience and unique approach to children’s eyewear that will make your kids want to wear their glasses. Schedule an eye exam today – you can book an appointment online right here. If you have any questions or concerns, give us a call and we’ll be glad to help.

Top 5 Tips for Managing Eye Allergies This Spring

Spring is a season of new beginnings, when the cold harsh winter months are behind us, flowers bloom, and people begin spending more time outdoors.

For people with allergies, spring means one more thing: suffering. Spring may be in the air, but for allergy sufferers, so is pollen, pet dander, mold, and dust. These airborne allergens can trigger uncomfortable reactions such as watery eyes, coughing, sneezing, congestion, and sinus pain.

There are some things you can do to minimize the discomfort throughout the spring season.

Check out Our Top 5 Tips for Getting Through Eye Allergy Season:

  1. Pollen tends to have a higher count in the mornings and early evenings. During these times, stay inside and keep windows closed. If you enjoy an early morning exercise run, consider an alternative indoor workout during peak allergy season.
  2. Take a shower before going to sleep. Doing this at night can rinse away any lingering allergens and leave you with a clearer eye and nasal area, as well as a more restful night’s sleep.
  3. Keep artificial tears close by. They can temporarily alleviate ocular allergy symptoms by lubricating your eyes when they feel dry and itchy, and they’re usually small enough to fit inside a purse or pocket. If you don’t have any good eye drops, use a cool compress as an alternative method of relief.
  4. If your allergies are caused by dust or pet dander, vacuum. A lot. Dust collects quickly and can be difficult to spot until there’s a high amount of it. Pets can shed fast and often, and just when you think you’ve removed all the fur from your sofa, carpet, or bed, you suddenly find more, so vacuum a few times each week.
  5. Wash your hands thoroughly with soap and water and change your linens more often during the spring season. Remnants of airborne allergens can stay on your hands, towels, and bed sheets. Washing them more frequently can minimize some of your allergic reactions.

Though it may be tempting, don’t rub your eyes. This can actually aggravate the allergy response. If you find yourself using artificial tears more than 4 times a day, or other short-term solutions aren’t enough, speak with your eye doctor. You may be able to receive antihistamine eye drops or other prescription medications to ease your discomfort.

When It’s More Than Allergies

Certain eye allergy symptoms can also be signs of eye conditions or diseases, so pay close attention to any reactions that don’t dissipate after allergy season ends.

These Eye Symptoms can include:

  • Dryness
  • Excessive tearing
  • Itchiness
  • Persistent eye pain
  • Redness
  • Swelling

These Symptoms Can Indicate Eye conditions, Such As:

  • Blepharitis (inflamed eyelids)
  • Conjunctivitis (pink eye)
  • Corneal Abrasions
  • Dry Eye Disease
  • Styes (an oil gland infection that causes a bump or pimple-like shape in the eyelid)

Eye Allergies and Contact Lenses

If you wear contact lenses, speak to your doctor about daily disposable contacts. These can be a great option for allergy sufferers. Since dailies are thrown away at the end of the day, there’s no heavy allergen buildup on the lenses to worry about.

Consider switching to eyeglasses for a while. Even the most comfortable soft lenses can feel irritable during allergy season. Use the springtime to get yourself a new look. With a wide range of incredible styles to choose from, including exclusive eyewear collections from today’s hottest designers, there’s something for everyone. Not sure what the choose? Talk to your optician to help you find a style that’s right for you.

Wal-Mart FAQs

Frequently Asked Patient Questions

Q. Are you employed by WalMart?

A. No. I am an independent doctor of optometry who chose to locate my practice at Wal-Mart, which is my landlord. I make no income from selling glasses or contacts, only from providing comprehensive exams and treating ocular disease.

Q. How can your fees be so much lower than other eye doctors? Will I receive a quality exam?

A. We provide a thorough exam with the most advanced diagnostic instruments to evaluate your vision needs and uncover any other ocular conditions that may go undetected, if not regularly monitored. I received my doctor’s degree after the same four years of training that all optometrists receive and was licensed to practice by the state after extensive testing. We can offer lower fees because our overhead is lower operating here, and we are able to keep busy seeing patients all day because of our convenient location.

Q. Will I receive a written prescription after the exam? Will the prescription be accepted anywhere?

A. We will supply a written prescription and summary of your exam as you leave the office.The prescription is valid anywhere in the U.S.

Q. I had an eye exam a little over a year ago, and my vision seems fine. Why do I need another exam?

A. We think it is important that all of our patients receive an annual eye exam. Your vision can change over a 12-month period. A regular check-up enables us to uncover any sight-threatening ocular conditions that can develop, unnoticed by you.

Q. Will you accept my insurance plan?

A. For the convenience of our patients, we accept most vision plans for whatever portion of the examination cost the plan covers. Please tell me your insurance company so that we can confirm your coverage.

Q. Why does it cost more for a contact lens exam?

A. We do additional testing with contact lens patients to measure the curvature of the eye to ensure that we prescribe the lens that optimizes fit and comfort. We also do an evaluation after you have worn the lenses for a given period to make sure there are no complications.

Q. Aren’t all contact lenses the same? Shouldn’t I just buy the cheapest ones?

A. They are not all the same. The contact lens companies spend millions of dollars every year to improve their lenses and regularly introduce new and better technology. You wouldn’t want to buy a five-year-old computer. For the same reason, it’s best to keep current and wear the latest and best lenses. Right now the companies are introducing new lens materials that allow much more oxygen to pass through, making them healthier to wear and enabling people to wear them in comfort for 14 hours or more per day. We recommend these new materials to most patients, even though they cost a little more, because we think they are better for their eyes in the long run.

Q. Will my contact lens prescription allow me to buy any brand of lens I want?

A. Your prescription is for a specific brand of contact lens that my examination and experience tell me is best for your vision and ocular health.

Q. Is it safe to wear a contact lens with a small tear in it?

A. A torn lens can damage the delicate outer tissue of your eye and lead to serious infection. If you tear a lens and do not have a replacement, come into the office right away and we will provide, at no charge, a lens that you can wear until your new supply arrives.

Q. Does WalMart make high quality glasses? Because they cost less, will they last as long and let me see well?

A. Wal-Mart will custom-make your glasses in one of its six ultra-modern optical labs, using top quality lens and frame materials, which the company constantly seeks to upgrade. Because of Wal-Mart’s buying power and operating efficiency, you receive top-quality glasses at an everyday low price.

Childhood myopia or nearsightedness is a common condition that causes blurred distance vision and can usually be easily corrected with either glasses or contact lenses. Unfortunately, simply getting a pair of glasses doesn’t always solve the problem, because often myopia is progressive which means that every year the vision gets worse. This usually continues until sometime around the child’s 20th birthday when his eyes stop growing and eyesight levels off.

It can be worrisome and quite disconcerting for both the parent and the child when each visit to the eye doctor results in a higher prescription. There could be a number of factors involved in progressive myopia, involving hereditary factors as well as possible environmental or behavioral factors such as frequent close-up tasks such as reading or using an electronic device. In fact, studies show that children that spend more time outdoors playing have a lower incidence of myopia.  Much research is currently being done into treatments for slowing or stopping myopia progression in children.

Here are some of the treatment options currently being offered:

Orthokeratology (Ortho-k)

Ortho-k is a process that uses specially designed rigid gas permeable contact lenses worn at night to gently reshape the cornea, eventually allowing clear vision during the day. The lenses are worn every night or every couple of nights depending on the results of the individual.  Ideal for mild to moderate myopia, ortho-k usually takes a few weeks to show results, during which time the patient may need to temporarily continue wearing glasses or contact lenses.

Studies show that the use of ortho-k can permanently reduce the progressive lengthening of the cornea which is responsible for nearsightedness and can, therefore, slow or stop the childhood progression of the condition.  Therefore, in addition to being used for myopia correction, it is now also being offered as a therapeutic treatment to halt myopia progression in children.

Multifocal Eyeglasses or Contact Lenses

Bifocal or multifocal soft contact lenses or glasses have been shown in some studies to slow myopia progression.  This therapy is based on the idea that the eye is strained from accommodating to see close up and that by providing multiple focusing powers, this allows the eye to relax when doing near work, which reduces the progression of the refractive error. This treatment has been shown to delay or slow the advancement of myopia in some children.

Atropine Drops

Treatment with atropine drops is another therapy that is used to relax the eye from “focusing fatigue” which may be a culprit in myopia progression. Research is still being done but some studies show that daily use of low doses of atropine drops do slow the progression of myopia. Atropine drops dilate the pupil which temporarily prevents the eye from being able to focus, thereby allowing this mechanism to relax. Research is still being done to determine dosages, but the results are promising.

If your child has progressive myopia, seek out a pediatric optometrist who is knowledgeable about the options available. Finding the right treatment could give your child the gift of better eyesight for life.

Macular Degeneration

Untreated macular degeneration is one of the leading causes of blindness in those over 65 years old.

While researchers have not yet discovered a cure for age-related macular degeneration (AMD), there are treatment options that prevent the disease from progressing to blindness, and in some cases, they can even improve vision. It’s important to have an open discussion with your eye doctor about the risks and limitations of AMD treatments.

Types of Macular Degeneration:

There are 2 basic types of AMD, the wet form and the dry form.

  • Dry macular degeneration is considered the less aggressive form of AMD. It typically progresses much more slowly, and the level of eyesight damage is less severe. Dry AMD is detected during routine eye exams, which is why it’s important to have yearly testing. Treating Dry AMD often involves high doses of zinc and antioxidants which have been shown to slow diseases progression.
  • Wet macular degeneration is the more severe form of AMD. Call us to book an emergency eye doctor's appointment if you experience a sudden worsening of blurry central vision. Wet AMD occurs when there is abnormal blood vessel growth (angiogenesis), and leakage, which can cause scar tissue to develop. Treatments include laser surgery, injecting light sensitive dyes, or AMD medication injected directly into the eye to inhibit angiogenesis.

AMD is an age related eye disease that runs in families, and is a leading cause of blindness in our aging population. There is no cure for this ocular disease, and AMD related vision loss is cannot usually be recovered. There are treatments, and preventative measures that can be taken, if detected early, so routine eye exams are essential.

Glaucoma Testing & Treatment

Glaucoma is a leading cause of preventable vision loss and blindness in adults in the United States and Canada and the second leading cause of blindness in the World, even more than macular degeneration.

What is Glaucoma?

Glaucoma is not a single disease. It is actually a group of eye diseases that cause damage to the optic nerve due to an increase in pressure inside the eye, which is called intraocular pressure (IOP). When detected in the early stages, glaucoma can often be controlled, preventing severe vision loss and blindness. However, symptoms of noticeable vision loss often only occur once the disease has progressed. This is why glaucoma is called “the sneak thief of sight”. Unfortunately, once vision is lost from the disease, it usually can’t be restored.

Treatments include medication or surgery that can regulate the IOP and slow down the progression of the disease to prevent further vision loss. The type of treatment depends on the type and the cause of glaucoma.

Risk Factors

Prevention is possible only with early detection and treatment. Since symptoms are often absent, regular eye exams which include a glaucoma screening are essential, particularly for individuals at risk of the disease. While anyone can get glaucoma, the following traits put you at a higher risk:

  • Age over 60
  • Hispanic or Latino descent, Asian descent
  • African Americans over the age of 40 (glaucoma is the leading cause of blindness in African Americans, 6-8 times more common than in Caucasians.)
  • Family history of glaucoma
  • Diabetics
  • People with severe nearsightedness
  • Certain medications (e.g. steroids)
  • Significant eye injury (even if it occurred in childhood)

Understanding Glaucoma

Signs and Symptoms of Glaucoma: Due to a buildup of pressure in the eye, glaucoma causes damage to the optic nerve which is responsible for transmitting visual information from the eye to the brain. How does glaucoma affect your vision?

Types of Glaucoma: There are a number of types of glaucoma, some more acute than others. Learn about the common types of glaucoma and the differences between them.

Diagnosis and Treatment of Glaucoma: Early detection and treatment of glaucoma are essential to stopping or slowing the disease progression and saving vision. Treatment can include medicated eye drops, pills, laser procedures and minor surgical procedures depending on the type and stage of glaucoma.

Signs and Symptoms of Glaucoma

The intraocular pressure caused by glaucoma can slowly damage the optic nerve, causing a gradual loss of vision. Vision loss begins with peripheral (side) vision, resulting in limited tunnel vision. Over time if left untreated, central vision will also be affected which will increase until it eventually causes total blindness. Unfortunately, any vision that is lost from the optic nerve damage cannot be restored.

What are the Symptoms?

Typically, glaucoma sets in without any symptoms. At the early onset of the most common type of glaucoma “open angle” glaucoma, vision remains normal and there is no pain or discomfort. This is why the disease is nicknamed the “sneak thief of sight”.

An acute type of glaucoma, called angle-closure glaucoma, can present sudden symptoms such as foggy, blurred vision, halos around lights, eye pain, headache and even nausea. This is a medical emergency and should be assessed immediately as the intraocular pressure can become extremely high and cause permanent damage within hours.

Types of Glaucoma

The primary forms of glaucoma are open-angle and narrow-angle, with open-angle being the most common type.

Primary open-angle glaucoma (POAG)

POAG gradually progresses without pain or noticeable vision loss initially affecting peripheral vision. By the time visual symptoms appear, irreparable damage has usually occurred, however, the sooner treatment starts the more vision loss can be prevented. When untreated, vision loss will eventually result in total loss of side vision (or tunnel vision) and eventually total vision loss.

Normal-tension glaucoma or low-tension glaucoma

This is another form of open-angle glaucoma in which the intraocular pressure remains within the normal level. The cause of this form of glaucoma is not known, but it is believed to have something to do with insufficient blood flow to the optic nerve, causing damage. Individuals of Japanese descent, women and those with a history of vascular disease or low blood pressure are at higher risk.

Angle-closure glaucoma

Acute angle-closure glaucoma is marked by a sudden increase in eye pressure, which can cause severe pain, blurred vision, halos, nausea, and headaches. The pressure is caused by a blockage in the fluid at the front of the eye which is a medical emergency and should be treated immediately. Without prompt treatment to clear the blockage vision can be permanently lost.

Congenital glaucoma

The inherited form of the disease that is present at birth. In these cases, babies are born with a defect that slows the normal drainage of fluid out of the eye; they are usually diagnosed by the time they turn one. There are typically some noticeable symptoms such as excessive tearing, cloudiness or haziness of the eyes, large or protruding eyes or light sensitivity. Surgery is usually performed, with a very high success rate, to restore full vision.

Secondary glaucomas

Glaucoma can develop as a complication of eye surgeries, injuries or other medical conditions such as cataracts, tumors, or a condition called uveitis which causes inflammation. Uncontrolled high blood pressure or diabetes can result in another serious form called neovascular glaucoma.

Pigmentary glaucoma

A rare form of glaucoma, this occurs when pigment from the iris sheds and clogs the drainage of fluid from the eye resulting in inflammation and damage to the eye and drainage system.

Treatment of glaucoma is dependant upon the severity and type of glaucoma present.

Glaucoma Diagnosis and Treatment

Detecting Glaucoma

During a routine comprehensive eye exam to check for glaucoma, your eye doctor will dilate your eye to examine the optic nerve for signs of glaucoma and will also measure the intraocular pressure (IOP) with an instrument called a tonometer.

IOP Measurement

Tonometry involves numbing the eye with drops and then gently pressing on the surface of the eye to measure the pressure. Since your IOP can fluctuate throughout the day and glaucoma can exist without elevated IOP this is not enough to rule out the disease. If there are signs of the disease, further testing will be performed.

Visual Field Test

A visual field test is designed to detect any blind spots in your peripheral or side field of vision. You will be asked to place your head in front of a machine while looking ahead and indicate when you see a signal in your peripheral field of view.

Retina Testing

Your doctor may also measure the thickness of the cornea with an ultrasonic wave instrument in a test called pachymetry or use imaging techniques such as digital retina scanning or optical coherence tomography (OCT) to create an image of your optic nerve to look for glaucoma damage.

Treating Glaucoma

Treatment for glaucoma depends on the type and severity of the disease and can include medication such as eye drops or pills or laser or traditional surgery.

Medication

Medication and drops to lower IOP are often the first resort for controlling pressure-related glaucoma. These drops may have some uncomfortable side effects, but compliance with the treatment plan is essential for preserving vision and halting the progression of the disease.

Surgery

Surgical procedures are designed to control the flow of fluids through the eye by either decreasing the amount of fluid produced or improving the drainage. Your doctor may decide that a combination of surgery and medication will be the most effective in many cases.

Prevention

It cannot be stressed enough that the most effective treatment for glaucoma happens when the disease is detected and treated early before significant vision loss occurs. Any vision that is lost cannot be restored. This is why the best prevention is awareness by knowing your risks and taking responsibility by having your eyes examined on a regular basis.

Diabetic Eye Disease

Diabetes is associated with several eye health issues including cataracts and glaucoma, but the most well known diabetic eye disease is diabetic retinopathy.

Diabetic Retinopathy

Diabetic retinopathy is an eye disease that only affects diabetics. It occurs when the fragile vascular network that supplies the retina – the light sensitive tissue at the back of the eye that helps us see – begins to swell or leak. During the beginning stages of the disease, there may be no noticeable symptoms, so it’s important to have your eyes checked at least once a year, if you have diabetes.

Once symptoms of diabetic retinopathy do develop, they can include: dark or black spots in your visual field, or blurry vision, and it increases over time. This is a result of bleeding at the back of the eye, which prevents a clear image from being transmitted from the retina to the brain.

Whether you have type 1, type 2, or even just gestational diabetes, you are at risk for developing diabetic retinopathy. The longer you have had the disease, the greater the risk. It is essential to keep your blood sugar levels under control to prevent vision loss, and this may require a trip back to your primary care physician.

Treating diabetic retinopathy can include vitrectomy, replacing the inner gel-like substance that supports the eyeball structure, and laser surgery.
