“…Visual impairment limits people's ability to perform daily tasks 3,4 and affects their quality of life. [5][6][7] Whereas most population-based studies have emphasized the importance of noncorrectable visual impairment, uncorrected refractive error has also been shown to affect the elderly, though to a lesser extent. 2,[4][5][6][7] Many cross-sectional studies have highlighted that the vision of a significant proportion of the elderly can be improved by wearing eyeglasses or changing the patient's existing glasses.…”

Purpose To report the 7-year incidence of uncorrected refractive error in a metropolitan Chinese elderly population. Methods The Shihpai Eye Study 2006 included 460/824 (55.8%) subjects (age range 72-94 years old) of 1361 participants in the 1999 baseline survey for a follow-up eye examination. Visual acuity was assessed using a Snellen chart, uncorrected refractive error was defined as presenting visual acuity (naked eye if without spectacles and with distance spectacles if worn) in the better eye of o6/12 that improved to no impairment (≥6/12) after refractive correction. Results The 7-year incidence of uncorrected refractive error was 10.5% (95% confidence interval (CI): 7.6-13.4%). 92.7% of participants with uncorrection and 77.8% with undercorrection were able to improve at least two lines of visual acuity by refractive correction. In multivariate analysis controlling for covariates, uncorrected refractive error was significantly related to myopia (relative risk (RR): 3.15; 95% CI: 1.31-7.58) and living alone (RR: 2.94; 95% CI 1.14-7.53), whereas distance spectacles worn during examination was protective (RR: 0.35; 95% CI: 0.14-0.88). Conclusion Our study indicated that the incidence of uncorrected refractive error was high (10.5%) in this elderly Chinese population. Living alone and myopia are predisposing factors, whereas wearing distance spectacles at examination is protective.

“…Prior focus group research has shown that mobility is not a problem at home in familiar surroundings for people with vision impairment. 21 This provides further support to conduct analyses separately depending on the location of the fall and to assess the functional status of people in both familiar and unfamiliar surroundings to determine their potential for falls.…”

“…22 The following vision-targeted subscales are generated: global vision rating (1 item), difficulty with near vision activities (3 items), difficulty with distance vision activities (3 items), limitations in social functioning due to vision (2 items), role limitations due to vision (2 items), dependency on others due to vision (3 items), mental health symptoms due to vision (4 items), driving diftravel. 14,15 In addition, mood and social relationships can be affected by visual impairment. 16 The main objectives of this study were to investigate, in patients with MS, the impact of visual impairment on 1) overall HRQOL in addition to other factors, such as disability and depression; and 2) various MS-specific HRQOL domains, including fatigue, mobility, mood, and social function.…”

The aim of this study was to evaluate the impact of visual impairment on health-related quality of life (HRQOL) in patients with multiple sclerosis (MS). Patients at an outpatient MS clinic were asked to complete a battery of patient-reported outcome questionnaires. Health-related quality of life was measured using the Hamburg Quality of Life Questionnaire for Multiple Sclerosis (HAQUAMS), while visual impairment was measured using the Visual Function Questionnaire (VFQ). Hierarchical regression was used to determine the relative contribution of visual impairment to HRQOL. Usable responses were obtained for 116 MS patients. Those with higher levels of visual impairment (lower scores on the VFQ) reported significantly lower HRQOL (β = –0.01, P = .0007). Visual impairment also explained an additional 4% variance in the HRQOL scores, independent of disability and depression (ΔR2 = 0.04, F7,108 = 36.58). Overall, disability was the strongest predictor of HRQOL, explaining over 60% of the variation in HRQOL scores. The model explained 70% of the total variance in HRQOL. Given the prevalence of visual impairment and its influence on overall HRQOL, MS patients should be routinely screened using standard ophthalmic examination procedures or self-administered questionnaires such as the VFQ.
