Q: I have 20/30 vision in my left eye and 20/400 in my right eye. I have a balance lens in my right eye and a prescription in my left. Does this make me legally blind or just blind in one eye?

A: Legal blindness is defined as best corrected visual acuity of 20/200 or worse in the better seeing eye or visual fields of 20 degrees or less. Since you have 20/30 vision in the left eye, you are not classified as legally blind based on visual acuity alone. – Linda Pang, O.D. at Lighthouse International

Q: I have been referred for a test requiring a dye injection for a small “'leak.” What is a leak and what causes it?

A: It would appear that your eye doctor is recommending a procedure known as fluorescein angiography. Fluorescein angiography is a method of evaluating the circulation in the retina as well as detecting a leaky blood vessel. The fluorescein dye gives off fluorescence and enables the photographs to reveal any areas of leakage in blood vessels. The fluorescence is very similar to museum exhibits that make rocks appear to “glow.” It is a very common method used to detect the leakage in patients with “wet” age-related macular degeneration. There are however reported side-effects that should be discussed with your doctor. -- Dr. Bruce Rosenthal, Chief of Low Vision Programs at Lighthouse International
