“…Considering results from population-based studies, this does not seem to be high. For example, data from India using the WG questions in a cross-sectional study suggested that 25% of those people with visual impairment also had moderate or severe hearing difficulties [11]. Also, a survey amongst adults registered with visual impairment in the UK suggested that “43% reported having hearing difficulties” [13].…”

“…Also, people with other disabling conditions are often more affected by visual problems because of the association of visual impairment and co-morbidities or intersecting disabilities, such as those caused by hearing difficulties, mental illness, etc. [11,12,13]. For example, people with Down syndrome have higher risks of developing co-morbid conditions such as refractive error.…”

Disability-disaggregated data are increasingly considered important to monitor progress in Universal Eye Health Care. Hospital-based data are still elusive because of the cultural ambiguities of the term disability, especially in under-resourced Health Information Systems in low-and middle-income countries. The aim of this study was to estimate the hospital-based rate of disability in patients presenting at an eye department of a rural hospital in Paraguay and to discuss implications for the management of access barriers. Therefore, we introduced two standardized sets of the Washington Group (WG) Questions as a pilot project. In total, 999 patients answered the self-report WG short set (WG-SS) questionnaire with six functional domains, and 501 of these patients answered an extended set, which included additional domains for “anxiety” and “depression” (WG-ES3). Overall, 27.7% (95% Confidence Interval (CI) 24.9–30.3) were categorized as having a disability. A total of 9.6% (95% CI 7.9–11.6) were categorized as having a disability because of communication difficulties, which was second only to visual difficulties. The odds ratio for disability for patients aged 70 years and older was 8.5 (95% CI 5.0–14.4) and for male patients, it was 0.83 (95% CI 0.62–1.1). Of those patients who answered the WG-ES3, 3.4% were categorized as having a disability because of being worried, nervous or anxious and 1.4% because of feeling depressed. An analysis of the questions of the “depression” domain was impeded by a high rate of measurement errors. The results of the different domains can now be used to inform the identification and mitigation of potential access barriers to eye health services for different types of impairments.

“…Prevalence of visual impairment among adults aged ≥ 18 years in this study was 16.8% (95% CI: 13.5, 20.2%) which is higher than other studies done in South Sudan (11.8%) [10], Cape Town South Africa (7.2%) [16], Sokoto state of Nigeria (11%) [17], Atakunmosa, South Western Nigeria (7.4%) [18], Bangladesh (9.3%) [19], Malaysia (9.2%) [20], South Korea (4.3%) [21], East Delhi district of India (11.4%) [6], Mahabubanagar district of India (8.4%) [22], Iran (1.39%) [23] and Botucato, Brazil (7.4%) [24].…”

Background: Visual impairment refers to presenting distance visual acuity worse than 6/18 in the worst eye. It remains a global challenge that greatly affects the mobility, social participation and the quality of life of the people. This study was aimed to determine the prevalence and associated factors of visual impairment among adults aged ≥ 18 years. Methods: A community-based cross-sectional study was conducted at Debre Berhan town. Systematic random sampling method was employed to select the study participants from adult's aged ≥18 years. Data was collected by interview with a pre-tested semi structured questionnaire. Both anterior and posterior segment ocular examinations were done by Optometrists and Ophthalmologist. After all ocular examinations adult's aged ≥18 years with presenting Visual acuity of < 6/18 in the worst eye were considered as visually impaired. Multivariate logistic regression was used to identify the determinant factors and p value less than 0.05 was considered as statistically significant. Results: A total of 416 participants were enrolled in the study with a 98.6% response rate. The prevalence of visual impairment among adults aged ≥ 18 years was 16.8% (95% CI, 13.5-20.2%). Among the overall prevalence of visually impaired adults 27 (6.49%) had bilateral VI and 43 (10.34%) had monocular VI. Aged > 64 years (AOR = 12.18, 95%CI: 4.47-33.20), illiterates AOR = 3.02, 95% CI: 1.36-6.72), previous eye trauma (AOR = 4.44, 95% CI: 1.64-12.04), family size > 5 (AOR: 4.44, 95% CI: 1.43-13.75) and family history of eye problem (AOR = 7.02, 95% CI: 1.95-25.22) had statistically significant association with visual impairment. Conclusions: Prevalence of visual impairment among adults was found to be a significant public health problem. Older age, illiterates, previous eye trauma, large family size and family history eye problem were positively associated with visual impairment.
