“…This finding agreed with the study conducted in China 30 . This might be due to an individual living in a rural area having poor eye care service utilization 31 . Similarly, this study showed that participants having nonformal educational status were 3.0 times more likely to have visually impaired as compared to participants having formal educational status.…”

Purpose: The study aimed to determine the prevalence, causes, and associated factors of visual impairment and blindnessamong the older population in Outreach sites, Northwest Ethiopia. Methods: A community-outreach-based cross-sectional study was conducted on 821 older population which were selectedusing a systematic random sampling technique. Face-to-face interviews and ocular examinations were performed to collect thedata. A binary logistic regression was performed. Result: A total of 821 participants were recruited for the study with a median age of 57 years, with a range of 40-91 years. Outof 821 participants, 41.8% had visual impairment, and 11.7% were blind. Sixty-four and fifty seven percent of visual impairmentand blindness were caused by cataract. Age ≥70years (AOR=15.0; 95%CI: 8.4-26.9), rural residency (AOR=2.3; 95%CI: 1.5-3.6),non-formal education (AOR=3.0; 95%CI: 1.6-5.6), unemployed (AOR=1.5;95%CI:1.05-2.4) and history of eye examination(AOR=1.7;95%CI:1.1-2.8) were positively associated with visual impairment. Similarly, blindness was significantly associatedwith age ≥ 70years (AOR=7.2; 95%CI: 3.1-16.6), rural residency (AOR=2.2;95%CI:1.2-4.2), and history of eye examination(AOR=1.9; 95%CI: 1.1- 3.3). Conclusion: The prevalence of visual impairment and blindness in this study was found to be high. Age, residency, educationalstatus, occupational status, and history of eye examination were significantly associated with visual impairment and blindness. Keywords: Visual impairment; blindness; older population; Northwest Ethiopia.

Purpose: To determine economic inequality in visual impairment (VI) and its determinants in the rural population of Iran. Methods: In this population-based, cross-sectional study, 3850 individuals, aged 3–93 years were selected from the north and southwest regions of Iran using multi-staged stratified cluster random sampling. The outcome was VI, measured in 20 feet. Economic status was constructed using principal component analysis on home assets. The concentration index ( C ) was used to determine inequality, and the gap between low and high economic groups was decomposed to explained and unexplained portions using the Oaxaca–Blinder decomposition method. Results: Of the 3850 individuals that were invited, 3314 participated in the study. The data of 3095 participants were finally analyzed. The C was −0.248 (95% confidence interval [CI]: −0.347 - −0.148), indicating a pro-poor inequality (concentration of VI in low economic group). The prevalence (95% CI) of VI was 1.72% (0.92–2.52) in the high economic group and 10.66% (8.84–12.48) in the low economic group with a gap of 8.94% (6.95–10.93) between the two groups. The explained and unexplained portions comprised 67.22% and 32.77% of the gap, respectively. Among the study variables, age (13.98%) and economic status (80.70%) were significant determinants of inequality in the explained portion. The variables of education (coefficient: −4.41; P < 0.001), age (coefficient: 14.09; P < 0.001), living place (coefficient: 6.96; P : 0.006), and economic status (coefficient: −7.37; P < 0.001) had significant effects on inequality in the unexplained portion. Conclusions: The result showed that VI had a higher concentration in the low economic group, and the major contributor of this inequality was economic status. Therefore, policymakers should formulate appropriate interventions to improve the economic status and alleviate economic inequality.

Abstract: VI is more frequent where eye care utilization is low. Domestic violence may be a risk factor for VI.
