The Impact of Vision Impairment on Vision-Specific Quality of Life in Germany

摘要: PURPOSE To validate the German-translated Impact of Vision Impairment (IVI) questionnaire, a vision-specific quality life (QoL) scale, and determine relationship between severity vision impairment, ocular conditions, VRQoL. METHODS This cross-sectional study was clinic based, with 184 patients low recruited from an outpatient at German eye hospital. Participants underwent clinical examination completed IVI scale. The validity scale assessed using Rasch analysis. main outcome measure overall functional emotional score provided by IVI. RESULTS Overall, there were more female (n = 111, 60.3%) than male participants. Participants' mean ± SD age visual acuity in better 69.0 15.5 years and. 0.41 0.35 logMAR, respectively. cause loss age-related macular degeneration 54, 29.3%). analysis demonstrated to assess VRQoL through two subscales: functioning well-being. In adjusted multivariate models, those mild or moderate/severe impairment reported significantly poorer (mean change, -6.5, P 0.018 -11.98, < 0.001 for moderate severe VI, respectively) well-being -2.35; 0.043 -3.13, 0.004 VI compared non-visually impaired patients. CONCLUSIONS Using psychometrically valid IVI, even independently associated poor These findings reinforce importance early preventative rehabilitative efforts prevent longitudinal deterioration loss.
