Researchers use patients’ cells to test gene therapy for rare eye disease

Scientists at the National Eye Institute (NEI) have developed a promising gene therapy strategy for a rare disease that causes severe vision loss in childhood.

Study suggests sugary diet endangers waste-eating protein crucial to cellular repair

A protein that functions like the vintage video game Pac-Man, eating toxic cellular waste caused by high sugar intake, is itself compromised by a sugary diet, according to the results of a study in mice with potential implications for humans.

How the Brain Learns That Earmuffs Are Not Valuable at the Beach

A new study from the University of Tsukuba in Japan and the NEI reveals how the brain learns to place different values on objects depending on the environmental context.

A Rift in the Retina May Help Repair the Optic Nerve

In experiments in mouse tissues and human cells, Johns Hopkins Medicine researchers say they have found that removing a membrane that lines the back of the eye may improve the success rate for regrowing nerve cells damaged by blinding diseases.

A Niche for the Eye

Research from the Stowers Institute suggests that the ciliary body might be key to detecting eye diseases before vision is impaired.

AI algorithms detect diabetic eye disease inconsistently

Researchers from UW Medicine have found that artificial intelligence-based screening algorithms to diagnose diabetic retinopathy do not perform as well as they claim.

Routine eye scans may give clues to cognitive decline in diabetes

Scientists at Joslin Diabetes Center now have shown that routine eye imaging can identify changes in the retina that may be associated with cognitive disorders in older people with type 1 diabetes.

VisionQuest Gains FDA 510(k) Clearance for the Image Quality Analyzer Software

The IQA is a software system intended for use in importing, displaying, analyzing and managing images acquired with digital fundus cameras. The patented software detects the most common causes of retinal imaging artifacts.

Tracing the many paths of vision

A team of scientists have created a molecular catalog that describes the different types of retinal ganglion cells in zebrafish, linking them to specific connections, functions, and behaviors.

Zika Virus Affects Eye Development Before But Not After Birth

A new study has found that Zika infection during the first trimester of pregnancy can impact fetal retinal development and cause congenital ocular anomalies. The virus does not appear to affect ocular growth postnatally.
