Glasses enhance mobility and function in patients who have difficulty with peripheral vision or seeing in low light UNIVERSITY OF SOUTHERN CALIFORNIA – HEALTH SCIENCES LOS ANGELES – Nearly one in 30 Americans over the age of 40 experience low vision — significant visual impairment that can’t be corrected with glasses, contact lenses, medication or surgery. In a new study of patients with retinitis pigmentosa, an...

Experimental drug delivers one-two punch to vision loss
by Johns Hopkins University School of Medicine In studies with lab-grown human cells and in mice, Johns Hopkins Medicine researchers have found that an experimentaldrug may be twice as good at fighting vision loss as previously thought. The new research shows that the compound, named AXT107, stops abnormal blood vessels in the eye from leaking vision-blocking fluids. These results build on previous research that...

Predicting vision loss in diabetes
A new study from a researcher at City, University of London has found that the location of lesions in the eye can help predict vision-threatening diabetic retinopathy, a frequent cause of blindness in the Western world. The paper, which is featured on the front page of the prestigious journal Diabetologica—a leading journal in diabetes research –...

Trigger for most common form of vision loss discovered
Jayakrishna Ambati, M.D., (left) and Nagaraj Kerur, Ph.D., have discovered a crucial trigger for macular degeneration, a condition which robs millions of their sight. The discovery may allow doctors to intervene early to halt the process. Credit: Josh Barney | UVA Health System In a major step forward in the battle against macular degeneration, the...

Scientists regenerate retinal cells in mice
Scientists have successfully regenerated cells in the retina of adult mice at the University of Washington School of Medicine in Seattle. Their results raise the hope that someday it may be possible to repair retinas damaged by trauma, glaucoma and other eye diseases. Their efforts are part of the UW Medicine Institute for Stem Cell...

New gene therapy for vision loss proven safe in humans
A fundus photo showing intermediate age-related macular degeneration. In a small and preliminary clinical trial, Johns Hopkins researchers and their collaborators have shown that an experimental gene therapy that uses viruses to introduce a therapeutic gene into the eye is safe and that it may be effective in preserving the vision of people with...
