Study uncovers new genetic risk factors for age-related macular degeneration, a leading cause of vision loss in adults.
Lab-created retinal cells created from human stem cells can reach out and connect to neighboring cells, a new study reports. The cells have the capacity to replace damaged retinal cells and carry sensory information. The findings could pave the way for clinical trials for the treatment of a range of diseases associated with vision loss and blindness.
Gene therapy enables a striking recovery of night vision in those who suffer from the childhood-onset blindness disorder Leber Congenital Amaurosis.
Administering a chemical compound called synthetic retinoids to the retina helped restore brain networks associated with vision and prompted the growth of two times more neurons, effectively restoring vision in adult mouse models of the genetic visual disorder LCA.
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.
