Summary
This study tested whether the antibiotic minocycline, taken as a pill twice daily for at least 3 years, could safely slow the growth of geographic atrophy—an advanced form of age-related macular degeneration that causes blind spots. Thirty-seven adults aged 55 and older with geographic atrophy in at least one eye participated. The main goal was to see if the drug reduced the rate of vision loss compared to a pre-treatment observation period.
