Eye imager quickly shows 80percent of retina

摘要

A triple-laser retinal imaging device designed to assist secondary eye-care practitioners in diagnosing, monitoring, and treating disorders such as diabetic retinopathy, glaucoma, diabetes, high blood pressure, age-related macular degeneration, and cancer is proving to be more effective than competing imaging systems in detecting disease earlier and potentially saving sight or even lives. The instrument, developed by Optos (Dunfermline, Scotland), has produced images showing approximately 80percent of the retina in a quarter of a second without irritation, according to Tom Daniells, vice president of marketing in North America for Optos. It can also check for leakage, assess tumors, monitor blood flow or oxygen levels, and look for bleeding. The system recently received marketing approval from the U.S. Food and Drug Administration and won the Royal Academy of Engineering MacRobert Award in London in June.
