Retinal FAQs

What specialized diagnostic tests are available to help identify retinal disorders?

I have been diagnosed with Macular Degeneration. Does this mean that I will go blind?

No. Macular degeneration affects only the central part of your vision. At its worst, macular degeneration causes great difficulty with detail vision such as reading and seeing faces, but you will always be able to see to walk around and do most activities of daily living.

Can I do anything to stop the progression of macular degeneration?

Some research seems to indicate that the use of zinc, antioxidants, and lutein may slow the progression of macular degeneration. Specialists also believe including spinach in one’s diet may be beneficial. Smoking doubles the risk of vision loss with macular degeneration.

Any other tips?

All patients with macular degeneration should have an Amsler grid (a checkerboard-like pattern) posted in a prominent place in their homes so that they see it every day. They should observe the grid with each eye independently daily. Should they note any new waves, distortions, or missing areas in the grid, or should they note any change in their vision, they should return for evaluation immediately.

Is there any treatment for Macular Degeneration?

Certain types of macular degeneration, if caught early, may be treatable with laser photocoagulation. Research is also being done using submacular surgery, macular translocation, radiation, and photodynamic therapy. But only with a timely examination and diagnosis can the treatment be optimized.

I have diabetes. Can this affect my vision?

Yes. Before one is diagnosed with diabetes and the stabilization of blood sugar levels achieved, the vision may fluctuate with blood sugar levels. It is usually not a good idea to get new glasses until the blood sugar is stable. Infrequently, diabetes can present with diplopia (double vision). Also, diabetics can develop cataracts at an early age, which fortunately is easily rectified with surgery.After several years, diabetes can cause leakage of blood and fluid into the retina which can result in loss of vision. At this point, laser treatment may be beneficial.In severe cases, diabetes can cause the growth of abnormal blood vessels in the retina and/or the vitreous. These new vessels are very fragile and can leak large amounts of blood into the eye or pull the retina out of position. We treat these vessels with laser photocoagulation. In resistant cases, the vitreous may need to be removed as well.

I have diabetes. How often should my eyes be examined?

All diabetics should schedule, at a minimum, a yearly exam including a dilated retinal evaluation. You may require monthly to quarterly exams, depending on the severity of your disease.

Can my general physician do my eye exams?

General medical doctors typically do not have the equipment to provide a detailed eye exam. These exams can be performed by your local optometrist, a general ophthalmologist, or a retinal subspecialist. Until laser or surgical treatment is indicated, a diabetic patient typically does not need to see a retinal subspecialist.
