About this trial
This randomized controlled clinical trial evaluates the efficacy of visual biofeedback training on visual function and quality of life in individuals with glaucoma. Glaucoma is a progressive optic neuropathy that can lead to irreversible vision loss, including impaired fixation stability, reduced retinal sensitivity, and decreased functional vision. Biofeedback training is a visual rehabilitation technique designed to help patients improve fixation stability and optimize use of remaining visual function by training eye movements toward retinal areas with better sensitivity.
Seventy participants with glaucoma will be randomized to either a biofeedback training intervention group or a control group. Visual function outcomes, including fixation stability, retinal sensitivity, visual acuity, reading speed, contrast sensitivity, and quality of life, will be assessed at baseline and follow-up visits. This study aims to determine whether biofeedback training can improve visual function and quality of life in patients with glaucoma.
