Retinal Texture Could Provide Early Biomarker Of Alzheimer’s Disease

May 14, 2020

Biomedical engineers at Duke University have devised a new imaging device capable of measuring the various layers of the retina at the back of the eye, which could be used to detect Alzheimer's disease.

Eyes send an unexpected signal to the brain

April 30, 2020

New research, led by Northwestern University, has found that a subset of retinal neurons sends inhibitory signals to the brain. Before, researchers believed the eye only sends excitatory signals.

Very low-dose Avastin effective for preventing blindness in preterm infants

April 23, 2020

Babies born prematurely who require treatment to prevent blindness from retinopathy of prematurity (ROP) could be treated with a dose of Avastin (bevacizumab) that is a fraction of the dose commonly used for ROP currently.

Researchers Find That Nicotinamide May Help Treat Fibrotic Eye Diseases and Mitigate Vision

April 2, 2020

Nicotinamide, a form of vitamin B3, can inhibit aggressive cell transformations during wound healing and may be key to the development of therapies to treat fibrotic eye diseases that impair vision.

‘Primitive’ Stem Cells Shown to Regenerate Blood Vessels in The Eye

March 9, 2020

Researchers turn back the biological hands of time, making adult cells revert to a primitive state with the potential to replace and repair retinal blood vessels.

Let there be 'circadian' light

February 20, 2020

Researchers at UW Medicine have decoded what makes good lighting – lighting capable of stimulating the cone photoreceptor inputs to specific neurons in the eye that regulate circadian rhythms.

How Do Fruit Flies See in Color?

January 9, 2020

Study from Columbia University uncovers human-like brain circuit at work. Their findings lay the groundwork for mapping mechanisms of color vision.

LSU Health discovers critical role of two proteins in vision and preventing blinding eye diseases

December 10, 2019

LSU researchers have discovered unique patterns of genetic activity that may lead to the development of blinding retinal diseases.

NIH, NIST researchers use artificial intelligence for quality control of stem cell-derived tissues

November 14, 2019

Researchers used artificial intelligence (AI) to evaluate stem cell-derived “patches” of retinal pigment epithelium (RPE) tissue for implanting into the eyes of patients with age-related macular degeneration (AMD), a leading cause of blindness.

Immune System Can Slow Degenerative Eye Disease, NIH-led Mouse Study Shows

June 17, 2019

A new study shows that the complement system, part of the innate immune system, plays a protective role to slow retinal degeneration in a mouse model of retinitis pigmentosa, an inherited eye disease.
