WebWire, March 23, 2007 GALVESTON, Texas - An international research team including scientists at the University of Texas Medical Branch at Galveston (UTMB) and the Galveston-based spinoff Neurobiotex, Inc. has found high levels of zinc in deposits in the eye that are an indication of age-related macular degeneration (AMD) - the leading cause of blindness in the elderly in the developed world. The finding, published this month in the journal Experimental Eye Research, contributes to a better understanding of AMD and could facilitate the development of effective treatments, said UTMB ophthalmologist Erik van Kuijk, senior author of the study.
