New target could help protect vision following optic nerve trauma

Scientists from the Medical College of Georgia at Augusta University have discovered that removing a pro-inflammatory enzyme promotes regeneration after an injury to the optic nerve.

NIH Researchers Home in on Genes Linked to Age-Related Macular Degeneration

National Eye Institute scientists led a collaborative study and zeroed in on genes associated with age-related macular degeneration (AMD), a leading cause of vision loss and blindness among people age 65 and older.

Microscopic eye movements affect how we see contrast

A team of researchers has discovered how the brain uses tiny, unconscious eye movements to pick up differences in brightness, likely by “refreshing” signals hitting the retina.

Faulty molecular master switch may contribute to AMD

A signaling pathway controlled by transforming growth factor β (TGF-β) could be involved in the progression of age-related macular degeneration (AMD).

Findings on eye-signal blending re-examine Nobel-winning research

“Our data suggest that the two eyes are merged as they arrive in the neocortex and not at a later stage of brain processing, as previously believed,” said Vanderbilt’s Alexander Maier, assistant professor of psychology.
A scanning electron micrograph image shows a polarized RPE monolayer on a biodegradable scaffold. The image is colored to highlight the scaffold in blue, three RPE cells (brown), and the apical processes of cells in RPE monolayer are light green.

NIH researchers rescue photoreceptors, prevent blindness in animal models of retinal degeneration

Using a novel patient-specific stem cell-based therapy, researchers at the National Eye Institute (NEI) prevented blindness in animal models of geographic atrophy, the advanced “dry” form of age-related macular degeneration (AMD)...
