The Effect of Intradialytic Eye Exercise in Hemodialysis Patients

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.
