New insights into how axons grow could lead to effective therapies for blindness, paralysis

Injuries to the nerves can blind or paralyze because adult nerve cells don't regenerate their connections. Now, a team of UConn School of Medicine researchers report in Development that at least a small population of nerve cells exist in everyone that could be coaxed to regrow, potentially restoring sight and movement.

New approach could help inform future lens design for treating myopia

Researchers have developed new instruments for rigorously quantifying and comparing the light-focusing properties of specialized eyeglass lenses that are used to slow the progression of myopia, or nearsightedness.

New small-molecule drugs show potential clinical utility in treating world’s leading causes of blindness

In a University of California, Irvine-led study, researchers have discovered small-molecule drugs with potential clinical utility in the treatment of age-related macular degeneration (AMD), diabetic retinopathy (DR), and retinitis pigmentosa (RP).

King Chulalongkorn Memorial Hospital ophthalmologists suggest ways to treat and control glaucoma

To celebrate World Glaucoma Week 2023, which takes place in the second week of March every year and falls on March 12-18, 2023, the Excellence Center for Glaucoma, Department of Ophthalmology, Faculty of Medicine, Chulalongkorn University, King Chulalongkorn Memorial Hospital, and Thai Glaucoma Society encourages all of us to realize the significance of glaucoma as it is the world's number 1 cause of irreversible blindness.

New deep learning AI model can help screen for retinopathy of prematurity in infants

The team developed a deep learning AI model that can identify which at-risk infants have ROP that may lead to blindness if left untreated, and they hope their technique could improve access to screening in the many areas with limited neonatal services and few trained ophthalmologists.

FDA-approved drug keeps light-sensitive photoreceptors alive in lab models of LCA 10

A National Institutes of Health 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.

Dormant cone photoreceptors in the degenerating retina may retain visual function, research suggests

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.
