Zinc could be key to eye disease
The mineral zinc may play a role in the development of a common cause of blindness, research suggests. Age-related macular degeneration (AMD) is the leading cause of blindness among elderly people in the developed world. Researchers found high zinc levels in deposits in the eye which are a marker for AMD development. The study, published in Experimental Eye Research and led by London's Institute of Ophthalmology, could help the development of new treatments.
