“…The prevalence of URE in this study is 1.8% which is consistent with the population-based Refractive Error Study in Children (RESC) conducted in South Africa (1.8%) (Naidoo et al, 2003). Nonetheless, it is lower than the prevalence from previous studies in Ghana by Ovenseri and Assien (13.3%) (Ovenseri-Ogbomo & Assien, 2010), Kuma et al (3.3%) (Kumah et al, 2013) and in other parts of Africa by Opubiri and Egbe (2.2%) (Opubiri et al, 2013), Balarabe et al (4.8%) (Balarabe et al, 2015) and Nebiyat et al (4.0%) (Tefera, 2015). Importantly, the variations in these studies could be attributed to the difference in study/geographical area (rural or urban), study samples, ethnicity, age group of participants in the study and the definitions and methods used for classifying refractive errors.…”

“…This finding is consistent with other studies conducted in Poland (13.3%) 17 and Amman city (17.6%). 22 However, compared with studies done in Tanzania (5.59%), Ghana (4.5%), and Nigeria (2.9%), 6 , 11 , 24 this finding is larger. The possible explanation could be that the proportion of female participants to male in this study was higher.…”

IntroductionMyopia is an important cause of correctable visual impairment and preventable blindness worldwide. Prevalence rates are approximately 20%–35% among the older teenage population globally. It has a medical burden of pathologic complications such as maculopathy and glaucomatous optic neuropathy. High school students experience high-performance and study pressures in the preparation for the final national examination. As a result they are exposed to excessive near work and indoor activities. They are also ignored for regular screening.ObjectiveTo determine the prevalence and associated factors of myopia among high school students in Gondar town, Ethiopia.MethodsAn institution-based cross-sectional study was conducted on 498 high school students with systematic random sampling method from April 18 to April 29, 2016, in three full-cycle high schools (9th–12th grades). A standardized structured questionnaire, Snellen acuity chart, pinhole, retinoscope, trial case lenses, pen torch, and direct ophthalmoscope were used to collect data.ResultsA total of 495 study participants were included, and they had a mean age of 17.48±1.59 years. The prevalence of myopia was 11.9% (95% confidence interval [CI]: 10.2, 17.9). Family history of myopia (adjusted odds ratio [AOR]=8.08 [95% CI: 4.30, 15.16]), school being private (AOR=2.88 [95% CI: 1.02, 8.11]), longer time spent for near work (AOR=2.89 [95% CI: 1.12, 7.43]), longer time spent partaking in indoor activities (AOR=4.32 [95% CI: 1.69, 10.99]), shorter near working distance (AOR=3.06 [95% CI: 1.33, 7.06]), lack of outdoor sport activities (AOR=2.27 [95% CI: 1.05, 4.90]), use of visual display units (AOR=2.81 [95% CI: 1.30, 6.10]), and abnormal ocular findings (AOR=6.69 [CI: 3.43, 13.03]) were found to be independently associated with myopia.ConclusionThe prevalence of myopia was 11.9%. Family history for myopia, school being private, longer time spent partaking in indoor activities, shorter working distance, lack of outdoor sport activities, use of visual display units, and presence of abnormal ocular findings were positively associated with myopia.

“…[9][10][11][12][13][14] Vision screening programs have been stratified by age; and several studies support the screening of infant/preschool children, highlighting its importance in the prevention of amblyopia and blindness. [15][16][17] In developed countries 18 and in Africa, 19,20 such screening exercises have been conducted in schools at various levels but targeting well-child clinics will facilitate assessing children's eyes at an earlier age. The Minnesota Expert Panel on Childhood Vision Screening 21 therefore advocates the screening of infants for ocular anomalies at every well-child visit, following the usual schedule.…”

Background: Vision screening in infants is an important part of the medical care of children as some eye abnormalities, if not treated in the first few months or years of life, can lead to irreversible vision loss. Objective: The objective of this cross-sectional, descriptive study was to identify ocular anomalies among infants attending immunization clinics in Nigeria and refer promptly and appropriately. Methodology: Infants were screened across 6 immunization clinics. Screening activities included relevant ocular history, vision assessment, external ocular examination, ocular motility, Hirschberg’s test, pupil examination, and the red reflex test. Infants with abnormal findings were referred for comprehensive eye examination. Result: Of the 142 infants who underwent vision screening, 29 were referred. These referrals were either as a result of ocular abnormalities (n = 22) or presence of risk factors from history (n = 7). The prevalence of ocular abnormalities was 15.5% and neonatal conjunctivitis (38%), was the commonest ocular abnormality found. Others were bacterial conjunctivitis (14%), nasolacrimal duct obstruction (14%), strabismus (14%), capillary hemangiomas (10%), iris nevi (5%), and vernal keratoconjunctivitis (5%). Of the 7 infants referred based on history alone, 6 (85.7%) had a history of prematurity. Conclusion: Conjunctivitis, strabismus, congenital nasolacrimal duct obstruction, and capillary hemangioma are some of the prevalent disorders seen in infants at immunization clinics in Nigeria. Babies at risk of retinopathy of prematurity (preterm birth and oxygen therapy) can be identified. Immunization clinics can serve as good points of vision screening for infants in developing countries to facilitate prompt referral and treatment.
