New UCI-led study lays foundation for establishing base editing as a one-time, durable treatment for inherited retinal degeneration

abril 5, 2022

A new study indicates base editing may provide long-lasting retinal protection and prevent vision deterioration in patients with inherited retinal degeneration, specifically in Leber congenital amaurosis (LCA) patients.

Turning back the clock on a severe vision disorder

marzo 31, 2021

Scientists at the University of Pennsylvania School of Veterinary Medicine report findings of a gene therapy to treat a severe form of Leber congenital amaurosis, caused by mutations in the NPHP5 gene.

Researchers use patients’ cells to test gene therapy for rare eye disease

enero 28, 2021

Scientists at the National Eye Institute (NEI) have developed a promising gene therapy strategy for a rare disease that causes severe vision loss in childhood.

LSU Health New Orleans Discovers Drug Development Target for Retinal Dystrophies

diciembre 1, 2020

A new study shows that deleting one of the inhibitors of the RPE65 gene in a mouse model that carries a human disease mutation prevents degeneration of cone photoreceptors that are used for daytime high-resolution color vision.

Success of gene therapy for a form of inherited blindness depends on timing

septiembre 9, 2019

Using a canine model of the vision disorder Leber congenital amaurosis, Penn researchers found that photoreceptor cells continue to deteriorate after treatment if it is given too late.
Multiphoton images show the outer segments of cone and rod photoreceptor cells in 215-day retinal organoids. Immunostaining shows a marker for cones (green) and rods (red). The “A” view shows optical sections; “B” is a reconstructed three-dimensional view.

NEI Awards Prize for Progress Toward Developing Lab-Made Retinas

NIH vision researcher T. Michael Redmond recognized with Champalimaud Vision Award

septiembre 4, 2018

Vision researcher, T. Michael Redmond, Ph.D., chief of the National Eye Institute (NEI) Laboratory of Retinal Cell and Molecular Biology, is a recipient of the 2018 António Champalimaud Vision Award for foundational science discoveries about the molecular

With LCA Gene Therapy, a Rare Glimpse of the Adult Brain Adapting to New Experience

agosto 4, 2015

When people lose the ability to see, how do the visual parts of the brain change in response? And if they regain their sight, are the changes reversed?
LCA is an inherited disorder that causes vision loss in childhood. It primarily affects the functioning of the retina, the light-sensitive tissue at the back of the eye, as shown here. Photo credit: National Eye Institute

NIH-funded Study Points Way Forward for Retinal Disease Gene Therapy

mayo 3, 2015

Gene therapy for Leber congenital amaurosis (LCA), an inherited disorder that causes vision loss starting in childhood, improved patients’ eyesight and the sensitivity of the retina within weeks of treatment.
