A new study published in Journal of Glaucoma found that primary open-angle glaucoma (POAG) patients with higher physical activity scores experienced slower rates of visual field loss. The research evaluated 131 eyes from 80 POAG patients who had five or more clinical visits, 2 or more years of follow-up visual fields, and underwent a physical activity questionnaire at baseline.
Je Hyun Seo, MD, PhD, Viterbi Family Department of Ophthalmology, Hamilton Glaucoma Center at the University of California, San Diego Shiley Eye Institute, and fellow researchers measured activity using the Physical Activity Index, metabolic equivalents of task (MET) minutes, and walking pace.
Results demonstrated slower visual field mean deviation loss was associated with increased physical activity.
The Importance of a Healthy Lifestyle
These findings strengthen and align with additional evidence that overall health, including exercise and other lifestyle choices, directly impact eye health beyond standard glaucoma treatments.
For instance, a June 2024 study in Journal of Glaucoma found that moderate-intensity aerobic exercise may result in transient reductions in intraocular pressure. Research also supports that increased cardiovascular activity boosts blood flow to the retina and optic nerve, safeguarding retinal cells from oxygen and nutrient deficits.
In addition, according to a 2023 study published in BMJ Open, avoidance of smoking and moderation of alcohol consumption are strongly associated with reduced risk of developing eye diseases, including glaucoma. Another 2023 study by Waspodo, et al found that by maintaining a healthy weight, patients can lower their risk of hypertension and diabetes, both of which are major factors in the development of glaucoma.
Informing Patient Discussions
Given this evidence, eye care professionals may consider routinely discussing lifestyle choices as part of comprehensive care plans for patients with glaucoma and other ocular conditions. Highlighting the connection between physical activity, nutrition, and healthy vision could encourage patients to adopt healthy living habits that bolster their lifelong eye wellness.
