| Popis: | Research question: what is the prevalence of manifest hypermetropia in primary school children (6 – 11 years ) of Gaza city? Objective: to study the prevalence of manifest hypermetropia in primary school children of Gaza city . Study design: cross sectional. Setting: schools of Gaza city –Palestine Participants: school children aged 6 – 11 years studying in 1st to 6th class. Study period: March 2013 to June 2013. Sample size: 1063 school children which included 478 females and 585 males. Study variables: manifest hypermetropic refractive error by age, sex and class, uncorrected, best corrected visual acuity and scientific achievement in school. Statistical analysis: Chi square test, proportions. Results: manifest hypermetropia is the most prevalent refractive error in primary school children in Gaza city irrespective of age or gender or eye . The prevalence of manifest hypermetropia is 45.3% for right eye and 46.7% for left eye. No statistically significant difference in scientific achievement in Arabic language or mathematics between children with various types of refractive errors. Conclusions: These data support the assumption that vision screening of school children in developing countries could be useful in detecting correctable causes of decreased vision especially refractive errors and in minimizing long term visual disability. |
