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, which is a complication of diabetes that affects the eyes, is detected during a comprehensive eye exam that includes:

  • Visual acuity testing.
  • Dilated exam in which drops are placed to widen the pupil to allow examination of the retina.
  • Tonometry. Measurement of the eye pressure inside the eye.

Supplemental testing may include:

  • Optical coherence tomography (OCT). This is a non-invasive test that images the retina to detect any fluid or diabetic macular edema.
  • Fluorescein Angiography. This test involves an injection of a dye into your arm and a series of pictures that are taken as the dye flows through the retinal vessels. This may show leakage of fluid or the growth of new blood vessels in the retina.

Treatment for Diabetic Retinopathy

The best treatment is prevention of diabetic retinopathy by strict control of blood sugars. Once diabetic retinopathy is present, treatment of diabetic retinopathy will slow progression but won’t cure it.

Diabetic macular edema can be treated with several different therapies that may be used alone or in combination.

These include:

  • Injection therapy. Anti-VEGF drugs are injected into the eye to block a substance called vascular endothelial growth factor (VEGF). This medication will block abnormal blood vessel growth and decrease the leakage of fluid into the retina. The three most commonly used drugs include Avastin, Lucentis and Eylea. Steroids are another option for treatment of diabetic macular edema but are used less often due to side effects of possible cataracts and increased eye pressure.
  • Laser therapy. Small laser burns are applied in the area of the retinal swelling to slow the leakage of fluid. Laser treatment can be combined with anti-VEGF injections.

Proliferative diabetic retinopathy can be treated with:

  • Laser therapy. Laser is applied on the retina to shrink the new blood vessels and to prevent bleeding inside the eye. Bleeding inside the eye will cloud the vision and cause floaters, which are small moving spots that appear in your field of vision.
  • Surgery. When there is significant amount of blood or scar tissue inside the eye, then a vitrectomy surgery is performed to remove the blood and scar tissue. Laser and anti-VEGF therapy may also be applied during the surgery.

In the end, the best treatment is prevention of diabetic retinopathy. An annual comprehensive dilated eye exam is recommended for anyone who has been diagnosed with diabetes, since early mild non-proliferative diabetic retinopathy can show no symptoms.
