“…82 There is considerable evidence that adults who are visually impaired have a poorer functional status in terms of ability to carry out both ADLs and IADLs than their fully sighted counterparts. 18,19,35,67,83,90,159 Lamoureux et al, for example, investigated the limitations in ADLs in 319 participants with a visual impairment with no visual rehabilitation history and found that reading, outdoor mobility, participation in leisure activities, and shopping were most limited. 90 Restricted mobility and orientation skills in individuals with visual impairment also make them more vulnerable to falls and associated complications such as hip fractures.…”

This is the unspecified version of the paper.This version of the publication may differ from the final published version. Permanent repository link Abstract.Visual impairment is a large and growing socioeconomic problem. Good evidence on rehabilitation outcomes is required to guide service development and improve the lives of people with sight loss.Of the 478 potentially relevant articles identified, only 58 studies met our liberal inclusion criteria, and of these only 7 were randomized controlled trials. Although the literature is sufficient to confirm that rehabilitation services result in improved clinical and functional ability outcomes, the effects on mood, vision-related quality of life (QoL) and health-related QoL are less clear. There are some good data on the performance of particular types of intervention, but almost no useful data about outcomes in children, those of working age and other minority groups. There were no reports on cost effectiveness. Overall, the number of well designed and adequately reported studies is pitifully small; visual rehabilitation research needs higher quality research. We highlight study design and reporting considerations and suggest a future research agenda.

Study Objectives: This questionnaire-based cross-sectional study was conducted (1) to estimate the prevalence of sleep-related problems, and (2) to explore factors associated with lower physical/mental quality of life (QOL), particularly addressing sleep-related problems among Japanese visually impaired people. Methods: This nationwide questionnaire-based survey was administered to visually impaired individuals through the Japan Federation of the Blind. Visually impaired individuals without light perception (LP) (n = 311), those with LP (n = 287), and age-matched and gender-matched controls (n = 615) were eligible for this study. Study questionnaires elicited demographic information, and information about visual impairment status, sleep-related problems, and health-related quality of life. Results: Visually impaired individuals with and without LP showed higher prevalence rates of irregular sleep-wake patterns and difficulty maintaining sleep than controls (34.7% and 29.4% vs. 15.8%, 60.1% and 46.7% vs. 26.8%, respectively; p < 0.001). These sleep-related problems were observed more frequently in visually impaired individuals without LP than in those with LP. Non-restorative sleep or excessive daytime sleepiness was associated with lower mental/physical QOL in visually impaired individuals with LP and in control subjects. However, visually impaired individuals without LP showed irregular sleepwake pattern or difficulty waking up at the desired time, which was associated with lower mental/physical QOL. Conclusions: Sleep-related problems were observed more frequently in visually impaired individuals than in controls. Moreover, the rates of difficulties were higher among subjects without LP. Sleep-related problems, especially circadian rhythm-related ones, can be associated with lower mental/physical QOL in visually impaired individuals without LP. Keywords: circadian rhythm sleep-wake disorder, health-related quality of life, light perception, prevalence, sleep-related problems, visual impairment I NTRO DUCTI O NVisually impaired individuals are likely to have any of several comorbid mental/physical disorders including diabetes mellitus, hypertension, cognitive impairment, and depression/ anxiety. [1][2][3][4][5][6] The severity of these mental/physical disorders is reportedly correlated with visual impairment.1-9 Therefore, those individuals might be at risk for lower health-related quality of life (QOL). 7-10Sleep-related problems have been observed frequently in visually impaired individuals.11-15 Reportedly, especially in people without light perception (LP), inhibited transmission of light signals to the suprachiasmatic nuclei might cause sleeprelated problems because of external desynchronization of the biological clock. 16,17 Indeed, the rate of circadian-related sleepwake disorders is likely to be higher among visually impaired individuals without LP than among those with LP.12 In Japan, no large nationwide study of this subject has ever been reported. The actual prevalence of sleep-related problems amon...

“…More recently there is a coming up of trend in developing a method for evaluation of functional vision-performance-based measures (PBMs) of visual function. [13][14][15][16][17][18][19][20][21][22][23] It involves presenting patients with commonly encountered tasks of daily life in a standardized format and getting a grade in accordance with their visual ability to complete the tasks.

Purpose Real-Life Vision Test (RLVT) is a newly developed performance-based measures of functional vision. This present study is designed to determine whether it could be a meaningful assessment for cataract surgery outcomes evaluation. Patients and methods Age-related cataract patients (56) who scheduled for bilateral cataract surgery and 44 age-matched controls were evaluated by four types of measurements: (1) demographic, medical, cognitive and depressive evaluation, and the reaction time testing; (2) clinical measures (visual acuity, contrast sensitivity, stereopsis, and color perception); (3) the 25-item National Eye Institute's Visual Functioning Questionnaire (NEI-VFQ); (4) the RLVT. Spearman's coefficients and multiple regression analysis were conducted to investigate the relationship among RLVT, clinical measures, and self-report assessment of visual function. Results The results of RLVT, clinical measures, and NEI-VFQ total scores were improved significantly after cataract surgery. There were no differences between control subjects and post-surgery patients with respect to NEI-VFQ-25 total scores, self-rating depression scale scores and three tasks of RLVT. Change of RLVT was significantly associated with the change of clinical measures in the cataract group. Multiple regression analysis demonstrated that change of distance, intermediate, and near visual acuity, and binocular contrast sensitivity were significant predictors of improvements of RLVT.Conclusions Cataract surgery could improve real-world visual ability effectively for cataract patients. Our study highlights the potential usefulness of RLVT as an adjunct to the current outcomes evaluation system for cataract surgery. The use of RLVT combined with clinical and self-survey methods may be the comprehensive strategy to manifest the impact of cataract surgery on patients' overall vision-related quality of life.
