Work in mice will contribute to the study of hereditary diseases that lead to blindness

... of the induction of neuronal degeneration neuronal for intense light exposure in the mouse's retina that will be helpful for the study of retinitis pigmentosa (RP), a group of hereditary diseases which lead to blindness and affect more than one million persons a year all over the world. In addition, the ...

Cats' eye diseases genetically linked to diseases in humans

... COLUMBIA, Mo. About one in 3,500 people are affected with retinitis pigmentosa (RP), a disease of the retina's visual cells that eventually leads to blindness. Now, a University of Missouri researcher has identified a genetic ...

Gene therapy restores vision to mice with retinal degeneration

... throughout the retina. "This is a proof of principle that someday we may be able to repair blindness in people with conditions like retinitis pigmentosa and macular degeneration," says Richard Masland, PhD, director of the Cellular Neurobiology Laboratory in the MGH Department of Neurosurgery. "There ...

New gene discovered for new form of intellectual disability

... and Mental Health (CAMH) has discovered a new form of intellectual disability involving mental retardation (MR) along with the eye defect retinitis pigmentosa (RP). CAMH also discovered the previously unidentified gene that causes this disorder, CC2D2A. This scientific advance will help understand the ...

Restoring sight, advances in fertility treatments and better visibility for pilots at FIO

A new way of looking at molecular motors

... Myosins also help parasites enter and infect hosts. Defects in the motors play a role in 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 ...

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

... the retina." Thus far, participants in the study have been people with little or no sight perception due to the degenerative eye disease retinitis pigmentosa (RP). Ultimately, however, the device is likely to be used for the millions of people suffering from age-related macular degeneration, or AMD, as ...

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

... while not a cure for blindness, the findings could lead to therapies for treating some forms of blindness, such as retinitis pigmentosa. Retinitis pigmentosa is a form of hereditary blindness where the rods and cones are destroyed, but the rest of the eye and retina remains intact. By switching on ...
