May is Healthy Vision Month

May is Healthy Vision Month

What does that mean for you? It means that now is the time to schedule a comprehensive eye  exam. 

While these are one of the exams we may often let fall by the wayside, they are extremely important to maintain our eye health. Comprehensive eye exams serve several purposes. During these exams, pupils, the circular black area in the center of the eye where light enters, are widened with eye drops or viewed without dilation through a special camera. This allows your Eye Doctor to check for vision problems and eye diseases, verify what stage of diseases your eyes may be in, and helps determine if you need glasses, contacts or other treatments. 

Comprehensive eye exams are crucial for all ages, here’s why: 

Pediatric exams test for visual acuity, lazy eye, color vision, ocular health, and more. These are extremely important to test for the school years ahead. 

For older children and teenagers, myopia (nearsightedness) is one of the biggest concerns that comprehensive eye exams detect. Myopia affects the eye’s ability to see distant images clearly. It is important to identify and treat early with glasses or contacts as children and teens begin to learn in larger spaces, play sports, and drive. 

Adult exams are recommended at least every two years, or as recommended by your eye care specialist. Exams for adults are necessary to catch eye conditions that can cause vision loss and even lead to blindness. Some of these conditions are cataracts, diabetic retinopathy, glaucoma, and age-related macular degeneration. 

There are several other conditions that comprehensive eye exams can expose that may not be found without a visit to your optometrist. 

Outside of eye exams, here are 5 ways you can help protect your vision: 

  1. Healthy eating. You know this! Healthy eating helps every part of your body. For your eyes, make sure to add dark, leafy greens and seafood that is high in omega-3 fatty acids to your plate. A great excuse to treat yourself to sushi! We’re adding a spicy sake maki roll to our cart… for delivery.
  2. Protective eyewear. Whether you’re chopping wood for the bonfire pit, mowing the lawn, painting your bedroom walls, or riding your motorcycle around town, protective eyewear is key. Blue-light protection glasses should also be considered to protect your eyes from all the time spent in front of computer screens.
  3. Sunglasses. Much like protective eyewear, sunglasses help protect your eyes from ultraviolet radiation delivered by sun. Not all sunglasses provide the same level of protection. Let us help you pick the best pair!
  4. Clean hands. Wash your hands before putting your contacts in and before taking your contacts out, simply to avoid infection.
  5. Stop smoking. Smoking is known to cause several diseases, but it can also lead to vision loss. It can increase the risk of age-related macular degeneration, cataracts, and more. Mark your calendar for your comprehensive eye exam and mark it as the day to stop smoking.

Diabetic retinopathy is an eye condition that affects the retina in people who have diabetes.

The retina is the light-sensitive tissue that lines the back of the eye, and detects light that is then processed as an image by the brain. Chronically high blood sugar or large fluctuations in blood sugar can damage the blood vessels in the retina. This can result in bleeding in the retina or leakage of fluid.

Diabetic retinopathy can be divided into non-proliferative or proliferative diabetic retinopathy.

Non-proliferative diabetic retinopathy: In the early stage of the disease, there is weakening of the blood vessels in the retina that causes out-pouching called microaneurysms. These microaneurysms can leak fluid into the retina. There can also be yellow deposits called hard exudates present in the retina from leaky vessels.

Diabetic macula edema is when the fluid leaks into the region of the retina called the macula. The macula is important for sharp, central vision needed for reading and driving. The accumulation of fluid in the macula causes blurry vision.

Proliferative diabetic retinopathy: As diabetic retinopathy progresses, new blood vessels grow on the surface of the retina. These blood vessels are fragile, which makes them likely to bleed into the vitreous, which is the clear gel that fills the middle of the eye. Bleeding inside the eye is seen as floaters or spots. Over time, scar tissue can then form on the surface of the retina and contract, leading to a retinal detachment. This is similar to wallpaper contracting and peeling away from the wall. If left untreated, retinal detachment can lead to loss of vision.

Symptoms of diabetic retinopathy:

  • Asymptomatic: In the early stages of mild non-proliferative diabetic retinopathy, the person will usually have no visual complaints. Therefore, it is important for people with diabetes to have a comprehensive dilated exam by their eye doctor once a year.
  • Floaters: This is usually from bleeding into the vitreous cavity from proliferative diabetic retinopathy.
  • Blurred vision: This can be the result of fluid leaking into the retina, causing diabetic macular edema.

Risk factors for diabetic retinopathy:

  • Blood sugar. Lower blood sugar will delay the onset and slow the progression of diabetic retinopathy. Chronically high blood sugar and the longer the duration of diabetes, the more likely chance of that person having diabetic retinopathy.
  • Medical conditions. People with high blood pressure and high cholesterol are at greater risk for developing diabetic retinopathy.
  • Ethnicity. Hispanics, African Americans and Native Americans are at greater risk for developing diabetic retinopathy.
  • Pregnancy. Women with diabetes could have an increased risk of developing diabetic retinopathy during pregnancy. If they already have diabetic retinopathy, it might worsen during pregnancy.
