My mother and one sister developed macular degeneration. It was a sad thing- the only good thing is that the person never goes totally blind, never lives in a dark world. There is always some light that reaches the eyes.

I have pictures I took of my mother that show her looking off into space rather than at the camera. In reality it was the only way she could 'see'.

At the ophthalmologist's I always have them check to see if my eyes are showing any such indication. So far, so good.
