“…The finding of this meta-analysis (5.26%) is consistent with the results of meta-analyses done in children in India in 2018 (5.3%) 60 and Nepal in 2023 (7.1%). 61 It is also in line with the result of a meta-analysis of childhood myopia and myopia in school children in Africa in 2022 (4.7%) 12,62 and comparable with the study finding in Ethiopia among school students (5.10%), 13 based on the results of 16 articles. The similarity in the study results may be due to approximate similarities in the study populations specifically their age.…”

“…In Ethiopia, the estimated prevalence of blindness and low vision due to URE was 7.8% and 33.4%, respectively. 45 Furthermore, the meta-analyses on the prevalence of REs among school students; the one conducted to estimate VI due to REs among children and adolescents, and the other stated VI among school children in Ethiopia reported 7.36% 13 and 6%, 46 and 6.13%, 47 respectively. However, those findings were based on a limited number of studies.…”

“…However, the authors believed that there were missing papers that were ignored by previous publications. 12 , 13 As a result, the authors conducted this review to clear the doubt about the precision of the extent of myopia in school-age children in Ethiopia. Therefore, the authors estimated the pooled prevalence of myopia in school-age children in Ethiopia with the maximum effort to include all the potential papers.…”

Objective: This study aimed to estimate the pooled prevalence of myopia among school-age children in Ethiopia. Methods: Eligible articles were searched from PubMed, Embase, and Web of Science databases. In addition, Google Scholar and reference lists of the retrieved articles were searched from 30 July 2022 to 02 January 2023. The preferred reporting of items for systematic reviews and meta-analysis was used to report the search results. Microsoft Excel was used to keep the data. The qualities of eligible studies were checked using the Joanna Briggs Institute critical appraisal checklist for prevalence studies. Analysis was held using STATA Version 11. The degree of heterogeneity was checked using I² statistics. The possible sources of heterogeneity were examined using meta-regression and subgroup analyses. The funnel plot and Egger’s test were used to assess the potential publication bias. A correction was made for publication bias using Duval and Twee Die’s trim-and-fill analysis. The systematic review registration number is PROSPERO (#CRD42022330541). Results: We identified 21 eligible articles including 20,757 subjects. Of those participants, 10,601 (51.1%) and 10,156 (48.9%) were males and females, respectively. A total of 15,152 (73%) participants were urban residents. The estimated prevalence of myopia among school-age children in Ethiopia was found to be 5.26% (95% confidence interval: 4.09–6.42). Conclusions: The prevalence of myopia among school-age children in Ethiopia is considerable, affecting one in 20 school-age children. Therefore, the authors recommend the stakeholders take extra steps to speed up the implementation of the school vision screening program and its integration plan into the existing school nutrition program.

“…This hospital-based study is also higher than several other community-based studies in Ethiopia, which have shown rates ranging from 4% to 12.9%. 18 , 29 , 30 This difference might also be explained by because of the study participants and study setting (ie, school children and the site of the study school).…”

Introduction Refractive error is a vision-impairing condition due to light rays not being able to focus on the retina, resulting in the visual outcome of a cloudy image. It is one of the main causes of central vision impairment globally and in Africa, including Ethiopia. This study was conducted to assess the magnitude of refractive error and its associated factors among patients attending ophthalmic clinics. Methods An institutional-based cross-sectional study design was utilized. A systematic random sampling technique was applied to select 356 participants. The data were gathered using an interview-structured questionnaire and check list. Then, the data were entered into Epi-data version 4.6 and transferred to SPSS version 25 for further clean up and analysis. Descriptive and analytical statistics were conducted. A binary logistic regression analysis was done, and variables with a p-value of less than 0.25 in univariate analysis were taken for bivariate analysis. Statistically significant was declared at a p-value of less than 0.05 with an adjusted odds ratio and 95% confidence interval. Results Among 356 participants, 96 (27.5%), with 95% CI (22.8, 32.1) had a refractive error, of which nearsighted is the most common type (15.8%). Regular use of electronic devices, near working distance (<33cm), less or lack of outdoor activities, history of diabetes mellitus and family history of refractive error were factors significantly associated with refractive error. Conclusion and Recommendations The magnitude of refractive error was 27.5%, which is relatively elevated than the previous studies. Clients need to get screened regularly so that refractive defects can be detected and corrected early. Eye care professionals shall make a big concern for patients with a history of diabetes and other medical illnesses since they are related to ocular refractive defects.
