“…Furthermore, this study indicated that glaucoma was the second cause of blindness and the third cause of visual impairment which was consistent with other studies done in Ethiopia 29 , Ghana 19 , South Africa 15 , and Afghanistan 20 . This might be due to the burden of glaucoma could be increased as age increases, its asymptomatic and asymmetric nature, low awareness of glaucoma, and poor seeking behaviours of eye care service.…”

“…This result is nearly agreed with other studies done in Debre Markos Referral Hospital Ethiopia(11.22%) 12 , Sudan (14%) 28 , and South Africa(10.9) 15 . In contrast, this finding is higher than the studies conducted in University of Gondar Tertiary eye care, Ethiopia(14.3%) 29 , Addis Ababa, Ethiopia (7.3%) 13 , Gurage Zone, Ethiopia(7.9%) 17 , Ghana (5.3%) 18 , Afghanistan(8.7%) 20 , North India(5%) 21 , Nepal(1.94%) 27 , Sri-Lanka(1.7) 23 , and Yugan county, China (2.27%) 25 . The difference observed here might be due to the difference in study locations, sampling size, eye care service-seeking behaviours, access to eye care service, and study population characteristics.…”

“…Besides, cataract (57.3%) was the main cause of blindness. This finding is supported by the studies conducted in Ethiopia 5 , 29 Ghana 14 , 18 , 19 , South Africa 15 , Afghanistan 20 , and India 22 . The possible reasons for these avoidable conditions as the leading cause of visual impairment and blindness globally particularly in developing countries might be due to low access to cataract surgery and corrective lens, social stigma for wearing spectacle, low awareness of conditions and its management, cost of treatment, availability of eye care service and waiting to maturity cataract.…”

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.

“…[28] Socio-economic status: Across developing and developed nations visual impairment is strongly associated with low socioeconomic status. [29] Though this study did not assess the socio-economic status of the participants, the demographics on the level of education and occupation indirectly reflected this association. (Table 2) Those with modest education had profound visual impairment.…”

The Magnitude of Low Vision and Blindness: Association with Socio-Demographic Determinants and Ocular Pathologies Amongst Adults in Enugu, South-East Nigeria

Background: Low vision and blindness are emerging public health challenges worldwide. Nigeria, despite being the home for growing elderly population, does not have well-structured, low vision and rehabilitative services. South-East zone of Nigeria has the highest prevalence of low vision in the country. The changing demographics and epidemiologic transitions call for urgent need to generate recent data on the magnitude of low vision and blindness and advocate for establishment of Low vision and rehabilitation services. This study evaluated the magnitude of low vision and blindness, and highlights its association with socio-demographic factors in adult patients. Methods: This is a cross-sectional hospital based study. A total of 400 participants were enrolled. Thorough ocular evaluation to confirm diagnosis of low vision / blindness was carried out. Data was analysed with SPSS 20.0. Descriptive and inferential statistics were done. Kruskal-Wallis, Chi-Square or Fisher exact test were performed where appropriate and a p-value of <0.5 was considered significant. Moderately Severe Visual Impairment, MSVI and Severe Visual impairment/ Legal Blindness accounted for 72.8% and 91.0% respectively amongst those that were above 41 years of age. Prevalence of Visual impairment increased with advancing age and low education was associated with VI. Conclusion: The study observed that advancing age is constantly associated with visual impairment and blindness. Glaucoma contributed significantly to impairment of vision. The study buttressed the need for development of low vision and rehabilitation services in the state. Knowing the huge economic consequences of low vision/blindness, stakeholders should be encouraged to invest in comprehensive eye care. Keywords: Low vision/Blindness, Elderly, Rehabilitation services

Pooled prevalence of blindness in Ethiopia: a systematic review and meta-analysis

Blindness is defined as presenting visual acuity worse than 3/60 in the better eye. Its highest proportion has been conforming to the developing countries such as Ethiopia. So, timely information is crucial to design strategies. However, the study on the magnitude of blindness in Ethiopia was outdated which means it was conducted in 2005–2006. Therefore, this study was proposed to estimate the pooled prevalence of blindness in Ethiopia.Databases like PubMed, Cochrane library, Google Scholar and references of retrieved articles were used to search for articles. A standard data extraction approach was employed and presented using Preferred Reporting of Items for Systematic Reviews and Meta-Analyses. The Newcastle-Ottawa Scale quality assessment tool was used to evaluate the quality of studies. Analysis held using STATA V.11. The funnel plot and Egger’s regression test were applied to check for the potential sources of bias. Heterogeneity among the studies was tested using I² statistics that have been calculated and compared with the standard. Meta-regression and subgroup analysis were done to identify the potential sources of heterogeneity. Estimation of blindness was carried out using Duval and Twee die’s trim and fill analysis. The pooled prevalence of blindness in Ethiopia is found to be 1.18% (95% CI 0.650% to 1.706%). Blindness is among the main public health difficulties in Ethiopia. So, it demands up-to-date strategies and its implementation, preventive and curative eye care service with affordable and accessible interventions, and evidence-based advocacy. The trial Registration Number is CRD42021268448.
