The Effect of Intradialytic Eye Exercise in Hemodialysis Patients
Sponsor: Pardis Specialized Wellness Institute
Summary
This pilot randomized trial will evaluate whether a structured intradialytic eye-exercise program can be delivered safely and consistently during maintenance hemodialysis and whether it shows preliminary promise for improving physical function, balance, and fall-related concern. The study is needed because hemodialysis patients commonly experience impaired physical performance, reduced balance, and fear of falling, and these problems are associated with higher fall risk; at the same time, supervised exercise during dialysis is increasingly viewed as a practical way to reach this medically complex and often sedentary population. Eye-movement and gaze-stability training has also shown benefit for balance- and fall-related outcomes in older adults and stroke survivors, but its feasibility and potential value during dialysis sessions remain uncertain.

Interventions
Intradialytic Eye Exercise
The participants in the study group will perform the eye exercise program while seated during hemodialysis treatment. The exercises will be administered face-to-face in the dialysis unit (not via teleconference). Each session will last 15 to 20 minutes and will be performed during clinically stable periods of dialysis. The program includes vestibulo-ocular reflex (VOR x1 and adaptation), saccadic eye movements (rapid shifts between targets), smooth pursuit (tracking moving targets), vergence (near-far focus), and integrated head-eye coordination exercises, performed in a seated position with progressive speed and complexity to enhance gaze stability and balance.
