Researchers at Aalto University developed an experimental laser-based heat treatment that may stop progression of dry age-related macular degeneration before severe blindness develops.
Dry AMD affects millions worldwide and lacks widely effective therapies that restore lost vision once retinal cells deteriorate.
The thermal approach targets early pathological changes in retinal tissue using precisely controlled energy delivery.
Ophthalmologists said preventive intervention would represent a major shift from managing late-stage vision loss to preserving function earlier in the disease course.
Clinical testing will be required to confirm safety, optimal timing and long-term outcomes in human patients.
Dry AMD progresses slowly but irreversibly in many patients, creating demand for interventions that halt retinal degeneration before central vision fails.
Laser thermal therapy differs from existing injections by targeting tissue changes earlier in the disease pathway identified in preclinical imaging studies.
Vision advocacy groups said preventive treatments would especially benefit aging populations facing limited options once geographic atrophy develops.
Retinal specialists said early intervention before geographic atrophy develops remains the primary unmet need in dry AMD management.
Regulatory pathways for laser-based retinal therapies require demonstration of precision dosing that avoids collateral thermal injury.
Ophthalmology conferences scheduled presentations on the laser heat treatment after peer review of the Aalto University dry AMD experimental findings.
Aalto University researchers developed an experimental thermal treatment that could halt dry AMD offering hope to millions facing progressive vision loss.
