Randomized Trial of Visual Biofeedback Training to Improve Vision and Quality of Life in Adults with Glaucoma

What this Trial Is About

Researchers are evaluating the effects of visual biofeedback training on visual function and quality of life in people with glaucoma, a condition that causes progressive optic nerve damage leading to vision loss. This trial aims to see if biofeedback training can improve fixation stability and help patients use their remaining vision more effectively. The study includes 70 participants diagnosed with glaucoma who have stable intraocular pressure and specific visual field impairments near the center of vision. Participants will be randomly assigned to one of two groups a biofeedback training group or a control group. Those in the biofeedback group will receive five weekly sessions of training lasting about 20 minutes each, where they will use visual and auditory feedback to guide their eye movements toward retinal areas with better sensitivity. The control group will have standard clinical assessments and will be offered biofeedback training after completing the control period. Participants will undergo various assessments at the start of the study and at follow-up visits including 9 weeks, 6 months, 1 year, and up to 2 years after the intervention. These assessments include measuring fixation stability, retinal sensitivity, visual acuity, reading speed, contrast sensitivity, and quality of life. The study will monitor changes over time to determine if biofeedback training can improve functional vision and life quality in glaucoma patients.
