Greater physical activity connected with slower visual field loss in glaucoma
Increased walking, greater time of moderate-to-vigorous physical activity and more time spent in non-sedentary activity are associated with slower rates of visual field loss in glaucoma patients.
These are the main conclusions of a study that were published in Ophtalmology journal.

Additional 5,000 daily steps or 2.6 hours of non-sedentary physical activity decreases the average rate of VF loss by roughly 10%q the research finds.
One hundred forty-one participants at a mean age 64.9 ± 5.8 years were enrolled. Eye mean deviation at the time of physical activity assessment was -6.6 dB and average steps per day was 5613 ± 3158.
Factors associated with a faster rate of VF loss included older age, non-Caucasian race, glaucoma surgery, cataract surgery, and moderate baseline VF damage (-6 dB≥MD>– 12 dB) as opposed to mild VF damage (MD>-6 dB). Similar associations between baseline accelerometer-measured physical activity and rates of VF loss were observed over other time periods (e.g., within 1, 3 and 5 years of activity assessment).
