Dr. Saperstein is a practicing ophthalmologist and an Associate Professor of Ophthalmology at the University of Washington in Seattle. Prior to this, he was an Assistant Professor of Ophthalmology at Emory University. Dr. Saperstein specializes in the medical and surgical treatment of retinal diseases and has a special interest in the treatment of age-related macular degeneration (AMD) and inherited retinal diseases. Dr. Saperstein has served as a primary investigator in several FDA pharmaceutical Phase 1, 2 and 3 clinical trials for AMD and other vision threatening disorders. Due to his experience in the field he has become a key opinion leader in the field of pharmaceutical treatments for retinal disease.

We add his clinical wisdom in macular degeneration to an advisory panel of world- class experts," said Albert Luderer, Ph.D., President, Visient Therapeutics, and President and CEO of parent company, Light Sciences. "As people grow older, their hope is to maintain their independence, and macular degeneration is among the leading causes of blindness -- the polar opposite of personal independence. Dr. Saperstein joins with us to tackle this pressing health issue," he added.

Dr. Saperstein joins incumbent ophthalmic experts on the Board, including ophthalmic laser and AMD pioneer Professor John Marshall, eminent ophthalmic surgeon and expert in diabetic retinopathy Peter Hamilton, and macular degeneration specialist and Founder and President of the Macula Foundation Dr. Lawrence A.
