Scientists track night vision changes in macular degeneration over 5 years

This study followed 57 people with age-related macular degeneration (AMD) for up to 5 years to see how their eyes adjust to darkness. Participants had yearly eye exams and dark adaptation tests, where they sat in a dark room and pressed a button when they saw a light. The goal was to understand how night vision changes as AMD progresses, not to test a new treatment.
