7 Light-activated eye drops restore vision in blind mice¶
Scientists at IBEC developed light-activated small-molecule drugs delivered as eye drops that restored light perception and visually guided behavior in blind mice without gene therapy, implants, or specialized lighting. The compounds target photoreceptor degeneration from diseases like age-related macular degeneration and retinitis pigmentosa affecting approximately 200 million people worldwide.
- Light-activated compounds restore vision without gene therapy or implants
- Two most promising compounds administered as eye drops or eye injections
- Target photoreceptor degeneration from AMD and retinitis pigmentosa
- Affect ~200 million people with these diseases globally; do not cure underlying degeneration
- Compounds show promising safety profiles
