Near-Infrared Laser Heat Treatment Shows Promise for Dry AMD
Overview
Dry age‑related macular degeneration (AMD) is a leading cause of blindness among people over 50. The condition gradually damages the macula, the central part of the retina responsible for sharp vision, leaving few effective treatment options.
How It Works
A new experimental approach from Aalto University uses near‑infrared laser light to gently warm retinal tissue. The controlled heat stimulates cellular “cleanup and repair” pathways, helping retinal cells clear out damaged components and support tissue health before irreversible vision loss occurs.
Potential Impact
If the technique can be safely translated to clinical practice, it could offer a preventative option for millions of individuals at risk of blindness from dry AMD—an area where few therapies currently exist.
Next Steps
Further studies are required to optimize laser parameters, confirm long‑term safety, and assess efficacy in human trials.
