The loss of blood flow autoregulation caused by diabetes is the result of the disruption of the TRPV2 protein. Even in the absence of diabetes, disrupted blood flow autoregulation causes damage closely resembling that seen in diabetic retinopathy.
Researchers have developed a cornea implant from the collagen protein of pig skin. The implant restored the vision of 20 people with diseased corneas. The new implant could be a viable alternative to human cornea transplantation.
Researchers say Black patients are at greater risk of advanced vision loss than white patients following a diagnosis of primary open angle glaucoma.
The visual system adapts to the loss of photoreception by increasing sensitivity but simultaneously becomes deleteriously hyperactive. The findings could lead to new therapies to protect vision or reverse vision loss.
Researchers have developed a new experimental human cell line from retinal pigment epithelial cells, dubbed ABC cells, that can assist with the study of blinding eye diseases, including age-related macular degeneration.
By the time most of us hit our 40s, our close-up vision starts to decline and we develop presbyopia. A new eye drop called Vuity claims to alleviate the symptoms of presbyopia, allowing people to gain clearer vision without the need for glasses or surgery. Researchers examine the potential benefits of using Vuity for people with presbyopia.
A new study reveals blind people remember speech and language better than sighted people. Researchers say blind people use language as a mental tool to remember information.
Antabuse, a drug commonly prescribed to treat alcohol use disorder, may help to restore eyesight in people with genetic retinitis pigmentosa and other disorders associated with retinal degeneration.
Fluoxetine, the antidepressant commonly known as Prozac, may be beneficial for the treatment of age-related macular degeneration. Researchers found Prozac significantly slowed the rate at which people over 50 developed AMD.
Researchers created a form of artificial vision for a blind woman with the aid of a brain implant position in the visual cortex. The results pave the way for the creation of visual brain prosthetics to help the blind to regain sight.
Findings upend the long-standing belief that blind people lack deep knowledge of visual phenomena.
