Vessel damage may precede diabetic retinopathy, researchers find
A University of Iowa-led study of diabetes-related vision impairment holds good news — and some bad news — for patients with signs of these disorders. Scientists have long known that patients with diabetes mellitus — both Type 1 and Type 2 — are at high risk for developing diabetic retinopathy, the most common cause of… Read More
Gene therapy shows long-term benefit for treating rare blindness
Pioneering gene therapy has restored some vision to patients with a rare form of genetic blindness for as long as four years, raising hopes it could be used to cure common causes of vision loss, new University of Oxford research published today shows. A technique which involves injecting a virus into the eye to deliver… Read More
Surprising central role of darks in brain visual maps
Scientists have been studying how visual space is mapped in the cerebral cortex for many decades under the assumption that the map is equal for lights and darks. Surprisingly, recent work demonstrates that visual brain maps are dark-centric and that, just as stars rotate around black holes in the Universe, lights rotate around darks in… Read More
Can an iPad help you see?
The proportion of older adults with age-related vision loss is estimated to be as high as one in three over the age of 50. In Canada, that’s roughly 3.6 million people. Many of these individuals turn to adaptive devices designed to magnify objects and text, but these devices can be prohibitively expensive, uni-functional and bulky…. Read More
