Ray Therapeutics develops optogenetic gene therapies for degenerative retinal diseases, reprogramming surviving retinal neurons to sense light and signal the brain. It targets patients with blinding conditions such as retinitis pigmentosa and Stargardt disease. Rather than replacing damaged cells, it repurposes neurons that remain after disease.
