“…In contrast, Nirmalan et al [ 32 ] and Emamian et al [ 33 ] reported that men were more likely to have received eye care services in hospitals in rural India and Northern Iran. Furthermore, a sex difference in the prevalence of visual impairment has been noted in both high-income and low-income countries [ 34 35 36 37 ]. The main cause of this disparity is that, in low-income countries, women use eye care services much less frequently [ 38 ].…”

PurposeTo estimate the factors and prevalence of eye care service utilization in the South Korean population.MethodsThis cross-sectional, population-based study included data from 22,550 Koreans aged ≥5 years who participated in the Korea National Health and Nutrition Examination Survey from 2010 to 2012. For people aged 5 to 11 years (young children), information was based on self-reports of contact with eye care service in the past year; for people aged ≥12 years (older population), the information was based on the self-reported lifetime contact with eye care service. Univariate and multivariate logistic regression analyses of the complex sample survey data were performed.ResultsThe prevalence of eye care service use in young children during the past year was 61.1% (95% confidence interval, 58.1%–64.1%), while that in the older population during their lifetime was 73.5%. Subjects aged 7 to 11 years were more likely to have had an eye examination in the past year than subjects aged 5 to 6 years (odds ratio, 3.83; 95% confidence interval, 2.37–6.19). Multivariate logistic regression analysis indicated that higher monthly household income, being a National Health Insurance holder, and having private health insurance were related to more frequent use of eye care services in young children. For the older population and women, those living in an urban area and those with a best-corrected visual acuity less than 20 / 40 in the worse-seeing eye were more likely to have had an eye examination during their lifetime. Low education level was associated with low lifetime use of eye care services in the older population.ConclusionsThere are sociodemographic disparities with use of eye care services in South Korea. This population-based study provides information that is useful for determining different intervention programs based on sociodemographic disparities to promote eye care service utilization in South Korea.

“…In 2012, myopia was estimated to affect 108 million people globally (Kandel et al, 2018;Stone & Shea, 2019). According to the 2010 Global Burden of Disease Study, approximately 1893 million people suffered from myopia worldwide in 2016 (Grzybowski, Kanclerz, & Muzyka-wo, 2019) Moreover, this number is estimated to increase to 4949 million by 2050, and the majority of these individuals will likely come from low-and middleincome countries (Ferraz, Corrente, Opromolla, & Schellini, 2014;Phec, 2017). Unfortunately, to date, no treatments are available to cure myopia or alter its progressive course unless a proper correction is given at the right time.…”

Background: Myopia is a global public health priority. Many modifiable and non modifiable risk factors have been shown to influence the development of myopia, but these factors are not adequately known by the general public. This study assessed public awareness of the factors that are associated with myopia among the general population in Kisumu County, Kenya. Methods: A cross-sectional study was conducted from October 2019 to February 2020 using an Internet-based questionnaire. We collected basic socio demographic characteristics and investigated participants’ knowledge of risk and protective factors that are associated with myopia. The primary outcome measures were the proportions of participants who identified each option as a risk factor. Logistic regression analysis was performed to compare levels of the knowledge of factors that are associated with myopia across populations with different demographic characteristics. Results: Data from a total of 3,000 respondents were analyzed. The percentages of participants who accurately identified myopia risk factors were the following: 84.24% for genetics, 65.07% for reading and close up work, 56.68% for environmental conditions, 48.74% for visual stress, and 42.66% for diabetes. The percentages of participants who accurately identified myopia corrections were as follows: 90.00% for corrective lenses, 84.69% for corneal refractive surgery and 80.92% for refractive surgery. The majority of Kisumu residents correctly recognized the role of lifestyle factors in the development of myopia but not genetic factors. Levels of knowledge of the factors that are associated with myopia were significantly distinct across populations with different characteristics. The following socio demographic characteristics were associated with more comprehensive knowledge of myopia risk and corrective measures: women, young age, high education levels, white- collar jobs, and history of myopia in a family. Conclusions: Public awareness and knowledge of risk and corrective measures for myopia in Kisumu is still insufficient. More efforts are needed to publicize information about myopia to reduce risk and prevent myopia

“…For example, in China, it has been seen that there is a moderately high occurrence of astigmatism among ages of 3–6 years ( 10 ). In Sao Paulo, uncorrected refractive error was found to cause blindness and low vision which, however, were reversible in 4.8% and 1.6% respectively among the Brazilian population ( 11 ).…”

BACKGROUND: Paediatric ophthalmology is an emerging subspecialty in Nigeria and as such there is paucity of data on refractive errors in the country. This study set out to determine the pattern of refractive errors in children attending an eye clinic in South West Nigeria. METHODS: A descriptive study of 180 consecutive subjects seen over a 2-year period. Presenting complaints, presenting visual acuity (PVA), age and sex were recorded. Clinical examination of the anterior and posterior segments of the eyes, extraocular muscle assessment and refraction were done. The types of refractive errors and their grades were determined. Corrected VA was obtained. Data was analysed using descriptive statistics in proportions, chi square with p value <0.05. RESULTS: The age range of subjects was between 3 and 16 years with mean age = 11.7 and SD = 0.51; with males making up 33.9%.The commonest presenting complaint was blurring of distant vision (40%), presenting visual acuity 6/9 (33.9%), normal vision constituted >75.0%, visual impairment20% and low vision 23.3%. Low grade spherical and cylindrical errors occurred most frequently (35.6% and 59.9% respectively). Regular astigmatism was significantly more common, P <0.001. The commonest diagnosis was simple myopic astigmatism (41.1%). Four cases of strabismus were seen. CONCLUSION: Simple spherical and cylindrical errors were the commonest types of refractive errors seen. Visual impairment and low vision occurred and could be a cause of absenteeism from school. Low-cost spectacle production or dispensing unit and health education are advocated for the prevention of visual impairment in a hospital set-up.
