Study on the Impact of Primary Open-Angle Glaucoma and Visual Field Loss on Mobility and Life Activities in Older Adults

What this Trial Is About

This research aims to understand how primary open-angle glaucoma POAG, a progressive eye condition affecting vision, influences mobility in older adults. Specifically, it evaluates the impact of POAG on life space, which refers to the range of places a person moves about regularly, and investigates whether difficulties with mobility are linked to challenges seeing under dim lighting conditions. Participants include people with POAG and those with healthy eyes. The study uses various diagnostic tests such as questionnaires about life space and vision in low light, assessments of contrast sensitivity and visual field under dim light, measurement of macular pigment density, and tests of dark adaptation. These assessments are conducted over approximately one year to compare visual function and mobility between groups. During the study, participants complete questionnaires, undergo vision tests under different lighting conditions, and have their visual pigment density measured. Researchers will analyze the relationship between visual function in dim environments and mobility. The study tracks these outcomes through the study duration, generally about one year, to better understand how vision changes affect daily movement and safety in older adults.
