Common antibiotic tested as potential first treatment for blinding eye disease

This study tested whether the oral antibiotic minocycline could safely slow the progression of geographic atrophy, an advanced and untreatable form of dry age-related macular degeneration that causes central vision loss. Participants aged 55+ with the condition took minocycline pills twice daily for up to three years while researchers tracked changes in their eye health and vision. The goal was to see if the drug could reduce the rate of damage to the retina.
