Optogenetics Therapy Enables Legally Blind Patients to Detect Objects in Early-Stage Study

A small, early-stage study published in the New England Journal of Medicine (NEJM) in 2026 reports that 10 legally blind individuals with advanced retinitis pigmentosa received an optogenetic therapy. Seven of these patients became more sensitive to light, and a smaller number were able to detect or locate simple objects while wearing special goggles. This marks the first time partial, object-related vision has been observed across a group of patients using this method.
