Prospective, observational study.

Participants wore an accelerometer over 7 days of normal activity.

Daily minutes of moderate or vigorous physical activity (MVPA) was the primary measure. Steps per day was a secondary measure.

Fifty-eight controls and 83 glaucoma subjects provided sufficient study days for analysis. Control and glaucoma subjects were similar in age, race, gender, employment status, cognitive ability, and comorbid illness (P>0.1 for all).
