Vision scientists discover new angle on path of light through photoreceptors

Researchers at the National Eye Institute (NEI) have discovered that power-producing organelles in the eye’s photoreceptor cells, called mitochondria, function as microlenses that help channel light to these cells’ outer segments.

Mosquitoes are seeing red: Why new findings about their vision could help you hide from these disease vectors

New research led by scientists at the University of Washington indicates that a common mosquito species — after detecting a telltale gas that we exhale — flies toward specific colors, including red, orange, black and cyan.

Implanted chip, natural eyesight coordinate vision in study of macular degeneration patients

A Stanford scientist and his colleagues show that patients fitted with a chip in their eye are able to integrate what the chip “sees” with objects their natural peripheral vision detects.
Cone photoreceptors from retinal organoids

UW study finds photoreceptor cells from retinal organoids can replicate key function of vision

Researchers from the U. of Wisconsin have shown that a retinal cell type derived from human pluripotent stem cells is capable of the complex process of detecting light and converting that signal to electrical waves.

Maintaining Transparency: Study to Focus on Causes of Cataracts

Researchers at the University of Arizona College of Medicine – Tucson are leading a study to identify the biological mechanisms that cause cataracts in the hopes that new, nonsurgical treatments may be developed.

UCI researchers discover cause, develop pharmacological treatment for reducing retinitis pigmentosa vision loss

Inhibiting ceramide accumulation in the retina helps preserve the retina’s structure and function, and improves vision.

AI can identify heart disease from an eye scan

Scientists have developed an artificial intelligence system that can analyze eye scans taken during a routine visit to an optician or eye clinic and identify patients at a high risk of a heart attack.

NIH study classifies vision loss and retinal changes in Stargardt disease

National Eye Institute researchers developed and validated an artificial-intelligence-based method to evaluate patients with Stargardt, an eye disease that can lead to childhood vision loss.

Study Finds Up to 30% of Patients with Wet Macular Degeneration Can Safely Stop Eye Injections

In a preliminary study, Johns Hopkins Medicine researchers report that as many as a third of those with "wet" age-related macular degeneration may someday be able to safely stop eye injection therapy without further vision loss.
