CRISPR Used to Repair Blindness-causing Genetic Defect in Patient-derived Stem Cells

Columbia University Medical Center (CUMC) and University of Iowa scientists have used a new gene-editing technology called CRISPR to repair a genetic mutation responsible for retinitis pigmentosa (RP), an inherited condition.

Gene Editing Technique Improves Vision in Rats with Inherited Blindness

A new technique that has the potential to treat inherited diseases by removing genetic defects has been shown for the first time to hinder retinitis pigmentosa, a degenerative eye disease with no known cure that can lead to blindness.

USC Eye Institute researchers discover a way to improve image sharpness for blind people with retinal implants

Retinal implants that deliver longer pulses of electrical current may noticeably improve image sharpness for individuals who have lost their sight due to retinitis pigmentosa, according to a new study.

Researchers Grow Retinal Nerve Cells in the Lab

Johns Hopkins researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain.

Gene Therapy Staves Off Blindness from Retinitis Pigmentosa in Canine Model

Gene therapy preserved vision in a study involving dogs with naturally occurring, late-stage retinitis pigmentosa, according to research funded by the National Eye Institute (NEI), part of the National Institutes of Health.
Dr. John Guy and colleagues added a homing signal to a virus in order to deliver the ND4 gene into mitochondria. A marker for the gene is shown in red and the ND4 protein is shown in green, inside retinal ganglion cells in the mouse eye. The nuclei of retinal ganglion cells are shown in blue.

Scientists Test New Gene Therapy for Vision Loss From a Mitochondrial Disease

Researchers funded by the National Institutes of Health have developed a novel mouse model for the vision disorder Leber hereditary optic neuropathy (LHON), and found that they can use gene therapy to improve visual function in the mice.

Defective Lens Protein Implicated in Cataract Shown Culprit in Presbyopia

Loss or defects of a protein previously shown to play a key a role in cataract, the clouding of the lens that commonly strikes people in their seventies, has now been shown to contribute to presbyopia.

Stem Cell Injection May Soon Reverse Vision Loss Caused By Age-Related Macular Degeneration

An injection of stem cells into the eye may soon slow or reverse the effects of early-stage age-related macular degeneration, according to new research from scientists at Cedars-Sinai.

HIV drugs show promise for “dry” AMD

A class of medications long used to curb HIV infection shows promise as a therapy for age-related macular degeneration (AMD), suggest findings from an NIH-funded study.
