[Purpose] This research investigated the relationship between balance measured by a TETRAX and activities of daily living (ADL) assessed by NEI-VFQ 25. The results should provide basic data for rehabilitation therapy for low-vision patients. [Methods] We used the NEI-VFQ-25 vision-related Activities of Daily Living evaluation, MMSE-K, and TETRAX to evaluate 30 low-vision outpatients at K hospital in Daejeon, South Korea from July 5 to July 23, 2012. We performed linear regression analysis using a statistical significance level of 0.05. [Results] Balance in the normal eyes open (NO) posture correlated with the normal eyes closed posture and age, but showed no correlation with NEI-VFQ 25. The ADL level correlated with monocular vision, female gender, cognition, and NO posture. These variables explained 54.4% of the aspects of their ADL. [Conclusion] This research proves that low vision adversely affects balance ability, and is influenced by type of vision, gender, and cognitive assessment.
