Scientists discover gene responsible for rare, inherited eye disease

Scientists at the National Institutes of Health (NIH) and their colleagues have identified a gene responsible for some inherited retinal diseases (IRDs), which are a group of disorders that damage the eye's light-sensing ...

Case series offers insights on corneal epithelial ingrowth after small incision lenticule extraction surgery

Corneal epithelial ingrowth (EI) is a rare but significant complication following small incision lenticule extraction (SMILE) surgery. Although this refractive procedure offers several advantages, such as a smaller incision ...

Immunology

Researchers discover new role of immune cells in eye health

The eye is an immune-privileged tissue because of the need to keep blood vessels away from the central pathway of light and to restrict entry of inflammatory cells that could cause damage. This has prompted questions about ...

First patient fitted with 3D-printed eye

A 3D-printed eye is a true biomimic and a more realistic prosthetic, with clearer definition and real depth to the pupil. Unlike traditional methods, it is made using digital scans of the eye instead of an invasive mold of ...

Neuroscience

Brief period of 'blindness' is essential for vision

Fixational eye movements are tiny movements of the eye—so small we humans aren't even aware of them. Yet they play a large role in our ability to see letters, numbers, and objects at a distance.

Map of mouse iris offers new look at the eye

If vision science were a movie, the iris would be a supporting actor. It doesn't get as much limelight as the retina, the eye's light-sensing tissue. And it's not as high-profile as the lens, which can cloud with cataracts ...
