i'm losing my vision. this doctor is a specialist in retinal disorders. he has gone out of his way to test me to make sure there are no other factors involved in the loss of my eyesight. he's doing everything humanly possible to help me keep my eyesight and explains it to me every step of the way with genuine concern. very rare these days in medicine he is an example to everyone in healthcare.
