Story summary

Researchers reported GLP-1 receptor agonist drugs are linked to lower risk of age-related macular degeneration (AMD).
The study followed GLP-1 users for a median of one year versus 2.5 years for a comparison group.
Authors said benefit could reflect retinal neuroprotection, weight loss, or both, noted a prior study linking a 2 percent AMD risk rise to each 1 kg/m² BMI increase, and urged research and trials in adults 50 years or older.
