MU researcher placing eye implants in cats to help humans see

...e worldwide is affected with a hereditary disease, retinitis pigmentosa, that causes the death of retinal cells and, eventually, blindness," Narfstrom said. "Our current study is aimed at determining safety issues in regard to the implants and to further develop surgical techniques. We also are examining the p...

Gene therapy for blindness clears hurdle in mice

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

...ases, such as age-related macular degeneration and retinitis pigmentosa, it is the loss of photoreceptors that leads to blindness. Understanding the birth of photoreceptors In 2001, Swaroop's team first showed that the gene NRL, discovered several years earlier in his U-M lab, is essential for the develop...

Study provides first look at the 'birth' of a retina cell

...root of eye diseases such as diabetic retinopathy, retinitis pigmentosa, and macular degeneration. In most instances, including age-related macular degeneration, rod photoreceptors die before cones. As the mouse eye develops, rods start out as stem cells, meaning they have not yet been assigned a function and...

'Prosthetic' retinal cells let blind mice see light

...es the defect in such inherited human disorders as retinitis pigmentosa. Unlike the retinal rods and cones that normally function as light-sensing cells in the eye, these retinal neurons are normally not photosensitive. The light-sensitive protein they used, called channelrhodopsin-2 (ChR2), is found in green ...

A new way of looking at molecular motors

...a variety of human and animal disorders, including retinitis pigmentosa (which causes blindness), polycystic kidney disease, brain development defects, neurodegenerative diseases, muscular dystrophy, skin pigmentation problems, and genetic hearing loss. Researchers led by Dominique Soldati, a Howard Hughes M...

Gene therapy works in mice to prevent blindness that strikes boys

...olve the eye's ability to process light, including retinitis pigmentosa, which affects about 200,000 people in the United States and is one of the most common inherited causes of blindness in people between the ages of 20 and 60. "We've been very successful in curing a disease in mice that has a direct copy i...

Six previously blind patients detect light, motion, identify objects with retinal prostheses

Ultimately, however, the device is likely to be used for the millions of people suffering from age-related macular degeneration, or AMD, as well. In fact, notes Humayun, there are 25 million people across the globe, including 6 milli...

Researchers discover way to make cells in the eye sensitive to light

...apies for treating some forms of blindness,such as retinitis pigmentosa. Retinitis pigmentosa is a form ofhereditary blindness where the rods and cones are destroyed, but therest of the eye and retina remains intact.
