Effects of Primary Open-angle Glaucoma on Visual-motor Coordination
Sponsor: Zhongshan Ophthalmic Center, Sun Yat-sen University
Summary
Commonly used visual function assessments in glaucoma diagnosis and treatment-such as visual acuity, visual field, and contrast sensitivity-do not directly capture the impact of the disease on patients' daily abilities. While questionnaires can evaluate this impact from the patient's perspective, they are subject to individual biases and inconsistent evaluation standards. Thus, objective methods are needed to assess patients' abilities in visually guided daily activities. Grasping objects and avoiding obstacles are fundamental visually guided tasks that require effective visuomotor coordination. By attaching lightweight reflective markers to participants' limbs and using a motion capture system to track their movements in three-dimensional space, various indicators of planning, execution, and control in tasks such as object grasping and obstacle avoidance can be quantified, allowing for an objective evaluation of visuomotor coordination. However, it remains unclear how visuomotor coordination is affected in glaucoma patients at different disease stages or whether visual field damage in specific areas has distinct impacts on visuomotor coordination. This study, therefore, aims to investigate changes in visuomotor coordination among patients with primary open-angle glaucoma across disease stages and to determine the effects of visual field defects in different locations on their visuomotor abilities.
