Subretinal device improves visual function in RP patients

August 1, 2003

Fort Lauderdale, FL-Visual function improvement is still apparent and better than ex-pected more than 3 years following the first implantation of a subretinal Artificial Silicon Retina (ASR, Optobionics Corp.) micro-chip in patients experiencing vision loss from retinitis pigmentosa (RP). This degree of improvement could be due at least in part to a neurotrophic effect, said Alan Y. Chow, MD, co-developer of the ASR.
