The visual system adapts to the loss of photoreception by increasing sensitivity but simultaneously becomes deleteriously hyperactive. The findings could lead to new therapies to protect vision or reverse vision loss.
Antabuse, a drug commonly prescribed to treat alcohol use disorder, may help to restore eyesight in people with genetic retinitis pigmentosa and other disorders associated with retinal degeneration.
Gene therapy that targets retinal ganglion cells with light-sensitive cone opsins helps restore vision in mice. Researchers report a potential human treatment could be available within three years.
New retinal implants could restore vision up to five times better than current technology, a new study reports.
Researchers decipher the retina's neural code for brain communication to create novel, more effective prosthetic retinal device for blindness.
Planarian flatworms have come under intense study for their renowned ability to regenerate any missing body part, even as adults. But now they may take on a starring role as a model system for studying eye development and eye diseases in vertebrates, including humans.
A team of University of California, Berkeley, scientists in collaboration with researchers at the University of Munich and University of Washington, in Seattle, has discovered a chemical that temporarily restores some vision to blind mice, and is working on an improved compound that may someday allow people with degenerative blindness to see again.
