Study Details

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.

Arms

  • Experimental: Biofeedback Training (BT)
    Participants randomized to this arm will receive visual biofeedback training in addition to standard clinical care. The intervention consists of five weekly in-office training sessions, each lasting approximately 20 minutes. During training, participants are guided using visual and auditory feedback to direct eye movements toward a preferred retinal locus with better retinal sensitivity and fixation stability. Visual function and quality of life assessments will be conducted at baseline and at scheduled follow-up visits.
  • Active Comparator: Control (Delayed Biofeedback Training)
    Participants randomized to this arm will undergo standard clinical assessments without biofeedback training during the initial study period. Visual function and quality of life assessments will be conducted at baseline and at the 9-week follow-up visit. After completion of the control period, participants will be offered biofeedback training as part of standard clinical care.
