Abstract

Abstract: : Purpose: The ability of patients with decreased vision due to age-related macular degeneration (AMD) to use computers may be improved by auditory and haptic feedback. We hypothesized that vision-specific quality of life (QOL) evaluated with the NEI-VFQ and time tradeoff utility (TTO) might be correlated with the extent to which computer task performance was improved by auditory and haptic (non-visual) feedback. Methods: Thirty patients with AMD completed a series of timed computer graphical user interface icon "drag and drop" tasks with and without auditory and haptic feedback. The mean task completion time was quantified using the final target highlight time (FTHT), measured in milliseconds. Prior to performing these tasks, vision-specific quality of life was assessed with the NEI-VFQ and a vision-related TTO utility question. For each patient, the improvement in milliseconds of FTHT associated with auditory and haptic feedback was calculated. The association between FTHT improvement and the QOL measures (after adjusting for weighted logMAR acuity and age) was evaluated using partial correlations. Results: The largest improvements in FTHT with auditory and haptic feedback were seen in the six patients with NEI-VFQ color vision scale scores less than 100%. Excluding patients without 100% color vision scores, the mental health (MH), social functioning (SF), and role difficulties (RD) VFQ scales demonstrated a correlation with FTHT improvement with auditory and/or haptic feedback. TTO was not correlated with improvement in FTHT. Conclusions: The NEI-VFQ was designed to assess vision-specific quality of life; however, higher scores in the MH, SF, and RD were found in those patients whose computer task performance improved with auditory and haptic (non-visual) feedback.
