Researchers at NIH’s National Eye Institute have published a detailed protocol for making three cell types that are key components to form blood vessels and capillaries.
In a new study, Sinha and his colleagues have now discovered anatomical changes that occur in the brains of these patients after their sight is restored. These changes, seen in the structure and organization of the brain’s white matter, appear to underlie some of the visual improvements that the researchers also observed in these patients.
A new study on herpes infections of the eye helps shed light on the question of viral reinfections by identifying a key protein involved in viral reinfections that could be targeted by antiviral drugs.
A study from the National Eye Institute (NEI) identified rare genetic variants that could point to one of the general mechanisms driving age-related macular degeneration (AMD), a common cause of vision loss in older adults.

A National Eye Institute-led team has identified a compound already approved by the U.S. Food and Drug Administration that keeps light-sensitive photoreceptors alive in three models of Leber congenital amaurosis type 10 (LCA 10), an inherited retinal ciliopathy disease that often results in severe visual impairment or blindness in early childhood.

New UCLA research in mice suggests that “dormant” cone photoreceptors in the degenerating retina are not dormant at all, but continue to function, producing responses to light and driving retinal activity for vision.
Corneal transplants can be the last step to returning clear vision to many patients suffering from eye disease. Each year, approximately 80,000 corneal transplantations take place in the U.S. Worldwide, more than 184,000 corneal transplantation surgeries are performed annually.
Using vision to efficiently move through an area by foot uses a unique region of the brain’s cortex, according to a small study funded by the National Eye Institute (NEI).
Researchers supported by the National Eye Institute are developing artificial intelligence/machine learning (AI/ML)-based systems that not only screen for AMD but also predict which patients will likely progress to late within two years. The systems also evaluate separately one’s risk for developing late wet (neovascular) AMD from one’s risk for late dry (geographic atrophy) AMD.

Cedars-Sinai investigators have produced the most extensive analysis to date of changes in the retina—a layer of tissue at the back of the eye where visual information originates—and how those retinal changes correspond to brain and cognitive changes in Alzheimer’s disease patients.
Questions remain about artificial tears linked to an outbreak of Pseudomonas aeruginosa infections involving 64 people in 13 states, including 8 cases of vision loss, as well as lung and urinary tract infections, and one death. Federal agencies warned people to stop using EzriCare and Delsam Pharma artificial tears after tests of opened bottles used by those affected found a rare, extensively drug-resistant strain of P. aeruginosa. The strain had never been reported in the United States.What is clear is that eye health experts have advice for people using artificial tears, which are sold over the counter and widely used for eye irritation associated with dry eye disease, contact lens use, and refractive surgery, as well among those using other eye drops regularly, such as for glaucoma.

Face blindness, a mystifying condition that can trick us into believing we recognize people we’ve never met or make us fail to recognize those we have, has been previously estimated to affect between 2 and 2.5 percent of people in the world. Now, a new study by researchers at Harvard Medical School (HMS) and the VA Boston Healthcare System is providing fresh insights into the disorder, suggesting it may be more common than currently believed.
While early treatment of diabetes-related eye disease slowed progression to severe disease, it did not improve visual acuity compared with treating more severe disease once it developed, according to a clinical study from the DRCR Retina Network.

People with diabetes who experience periods of low blood sugar — a common occurrence in those new to blood sugar management — are more likely to have worsening diabetic eye disease. Now, researchers at Johns Hopkins Medicine say they have linked such low blood sugar levels with a molecular pathway that is turned on in oxygen-starved cells in the eye.
