Study summary

Glaucoma is a chronic progressive eye disease characterized by visual field loss, which may adversely affect postural control, functional mobility, and increase the risk and fear of falling. This randomized controlled trial aims to investigate the effects of balance training on balance performance, fall risk, and fear of falling in individuals with glaucoma. Participants will be randomly assigned to either a balance training group or a control group. The intervention group will participate in a structured balance training program for eight weeks, while the control group will continue their routine medical care. Balance performance, functional mobility/fall risk, and fear of falling will be assessed using the Berg Balance Scale, Timed Up and Go Test, and Falls Efficacy Scale-Internatio

Inclusion criteria

  • Being over 18 years of age
  • Diagnosis of primary open-angle glaucoma
  • Glaucoma treatment being stable for the last 3 months (Stable treatment is defined as: no changes to anti-glaucoma medication, no new surgical or laser treatments, and no clinical findings during routine eye examinations necessitating a change in treatment within the last 3 months.)
  • Ability to walk independently
  • Ability to understand and follow simple verbal commands
  • General health status suitable for participating in balance exercises
  • Willingness to participate in the study and provide written informed consent

Exclusion criteria

Exclusion Criteria:

  • Having undergone eye surgery within the last 3 months
  • Presence of an eye disease other than glaucoma that could significantly affect balance (e.g., advanced cataract, age-related macular degeneration, proliferative diabetic retinopathy)
  • Presence of stroke, Parkinson's disease, multiple sclerosis, or other neurological disorders
  • History of vestibular system disorder
  • Lower extremity orthopedic condition significantly affecting balance and gait, or lower extremity surgery within the last 6 months
  • Presence of cognitive or psychiatric disorders that would hinder adherence to the study
  • Presence of severe cardiopulmonary disease that would prevent participation in exercise
  • Participation in a regular balance exercise or vestibular rehabilitation program within the last 6 months

Study arms

  • Experimental
    Balance Training Group

    Participants in this group will receive a structured balance training program for 8 weeks in addition to their routine glaucoma care. The balance training program will include static and dynamic balance exercises, gait-related balance activities, and progressive postural control exercises.

    Behavioral: Balance Training Program

  • No intervention
    Control Group

    Participants in this group will continue their routine glaucoma care and will not receive the balance training program during the 8-week study period. Outcome assessments will be performed at baseline and at the end of 8 weeks using the same assessment procedures as the balance training group.

Interventions

  • BehavioralBalance Training Program

    Participants allocated to the intervention group will participate in a structured balance training program for 8 weeks, three days per week, with each session lasting approximately 45 minutes. The program will include static and dynamic balance exercises, such as tandem stance, single-leg stance, tandem walking, heel-to-toe walking, directional changes, sit-to-stand exercises, and progressive postural control activities. Exercise difficulty will be progressively increased according to each participant's functional capacity and tolerance. All exercise sessions will be performed under supervision, with appropriate safety precautions to minimize the risk of falls. Participants will continue their routine glaucoma treatment throughout the study.

What researchers measure

Primary outcomes

  1. Change in Balance Performance Assessed by the Berg Balance Scale

    Balance performance will be assessed using the Berg Balance Scale (BBS), a 14-item performance-based measure of static and dynamic balance. Each item is scored from 0 to 4, resulting in a total score ranging from 0 to 56. Higher scores indicate better balance performance. The change in BBS score from baseline to the end of the 8-week intervention will be evaluated.

    Time frame: Baseline and 8 weeks

Secondary outcomes

  1. Change in Functional Mobility and Fall Risk Assessed by the Timed Up and Go Test (TUG)

    Functional mobility and fall risk will be assessed using the Timed Up and Go Test (TUG). Participants will be instructed to stand up from a standard chair, walk a distance of 3 meters, turn around, walk back to the chair, and sit down. The time required to complete the test will be recorded in seconds. A longer completion time indicates poorer functional mobility and a higher fall risk. The change in TUG time from baseline to the end of the 8-week intervention will be evaluated.

    Time frame: Baseline and 8 weeks

Other outcomes

  1. Change in Fear of Falling Assessed by the Falls Efficacy Scale-International (FES-I)

    Fear of falling will be assessed using the Falls Efficacy Scale-International (FES-I), a 16-item questionnaire evaluating concern about falling during various daily activities. Each item is scored from 1 to 4, resulting in a total score ranging from 16 to 64. Higher scores indicate greater concern about falling. The change in FES-I score from baseline to the end of the 8-week intervention will be evaluated.

    Time frame: Baseline and 8 weeks

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Aug 2026 (actual). Primary completion is estimated for Dec 2026, 4 months after the start.

Of 273 non-industry interventional studies with no phase under Glaucoma, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 55. This study's planned 4 months is below that.

Counting every sponsor, half of 356 studies reached it within 29 months; a quarter within 15 and three quarters within 55.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
