Purpose: Refractive errors are among the most common causes of vision loss in patients attending healthcare facilities in the first and second decades of life. Astigmatism is one of the common and treatable causes of vision loss in pediatrics.
Material and Methods: in this cross-sectional study, the samples were chosen by random cluster sampling among children aged between 7 and 13 from elementary schools in XX (X) in 2014-2015. For all students, refractive errors were performed by autorefractor Keratometer and retinoscopy. Internal astigmatism was defined as the difference between refractory and corneal astigmatism. SPSS version 16 was used for data analysis.
Results: 1009 patients participated in the study. Among the participants, 468(46.4%) were male, and 541 (53.6%) were female. The mean age in this study was 9.2±1.7 years old. A total of 14.5% of patients had refractory astigmatism. Corneal astigmatism was the most common type of astigmatism, with 12.5% of students suffering from it, and the prevalence of corneal astigmatism was not significantly different between males and females(p= 0.19), Also, there was no significant relationship between increasing age and prevalence of astigmatism in this age group (p=0.06).
Conclusion: In this study, there was no significant difference in the rate of refractory astigmatism, lenticular and corneal astigmatism, between males and females. Regarding the fact, that correcting refractory errors in students has a positive effect on learning ability and physical and mental development. Screening and follow-up are recommended.
