An organisation representing people with eye diseases is warning that more than 100,000 people could be driving with partial blindness and not know it.

A unique nanoparticle made in a laboratory at the University of Central Florida is proving promising as a drug delivery device for treating glaucoma, an eye disease that can cause blindness and affects millions of people worldwide.

Almost one-third of older Americans diagnosed with primary open angle glaucoma (POAG) are not treated medically or surgically for the condition according to a study to be presented at the Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting in Fort Lauderdale, Fla. The presentation will be held on Monday, May 7, 2007, at 11:45 a.m. in the Grand Floridian H of the Greater Fort Lauderdale/Broward County Convention Center.

Many young and middle-aged people of Chinese ancestry told they are at risk of going blind from glaucoma may be getting incorrect information, say researchers at the Stanford University School of Medicine.
