  • Title: Prevalence of refractive error and low vision among schoolchildren in Cairo.
    Author: El-Bayoumy BM, Saad A, Choudhury AH.
    Journal: East Mediterr Health J; 2007; 13(3):575-9. PubMed ID: 17687830.
    Abstract:
    A preliminary survey was conducted to detect the prevalence of refractive error (RE) and low vision among 5839 schoolchildren aged 7-14 years in Cairo, Egypt. Screening was done using Landolt broken ring chart and pinhole test. The prevalence of RE (visual acuity < or = 6/12) among the schoolchildren was 22.1% and low vision (visual acuity < or = 6/18) was 12.5%. The prevalence of low vision was greatest among the preparatory schoolchildren aged 12+ years. RE was higher among the female students than males (21.4% and 13.6% respectively). Development of a national survey for detection of visual problems for both preschool and school-aged children is recommended.
