Optogenetics trial restores some vision for retinitis pigmentosa patients in small study
A new study published Wednesday in the New England Journal of Medicine reports that optogenetics restored partial vision to patients with retinitis pigmentosa.
Study details and publication
Researchers presented findings from a small clinical trial on Wednesday. The results appeared in the New England Journal of Medicine. This research focuses on a genetic disorder affecting light-sensing cells in the retina.
Patient condition and history
Retinitis pigmentosa typically causes patients to lose peripheral and night vision during childhood or early adolescence. Many individuals become legally blind by young adulthood without intervention. Only a subset of patients with specific mutations currently receive gene therapy.
Technology and potential impact
Optogenetics is the technology recognized with a Nobel Prize that offers hope for these cases. The method aims to restore function where previous measures only slowed degeneration. No cure exists for the condition outside of this specific genetic subset.
