Objective: Comments on refractive error (RE) characteristics of primary school age and to analyze some relative factors. Methodology: patients aged 612 with RE visited VNIO. Invalid patients: unable to be checked RE. Design: cross-sectional study. Taking history, reasons and previous treatment. examination: RE measured both before and after cydoplegla
diagnosing RE and degree of astigmatism. Analyses of RE results by age groups, sex, after plegia and measurement methods. Data processing: Epi-Info 6.0. Results: 52.44 percent patients coming by blurry vision
53.64 percent by late examination
36.6 percent corrected by glasses
of whom 25 percent of myopia patients overcorrected by glasses. Measured by sphericalequivalent . refractive error (SE)
71.95 percent, 21.34 percent
2.44 percent are slight, average and severe levels respectively. 90.24 percent astigmatism (Induding physiological astigmatism)
of which, 94.59 percent with-therule
4.06 percent against-the-rule and oblique astigmatism. 35.37 percent anisometropia and 4 diopters In maximum. The myopia rate Increases with age group. SE level in pre and post-accomodative palsy was different by 0.42D in average and the highest is 3.5D. Refraction results were related with age groups, using cydoplegia medldne and measurement methods. Conclusions: 52.44 percent patients coming by blurry vision
53.64 percent by late examination
36.6 percent corrected by glasses, of whom 25 percent of myopia patients overcorrected by glasses. 71.95 percent, 21.34 percent
2.44 percent are slight, average and severe levels respectively. 90.24 percent astigmatism. 35.37 percent anisometropia and 4 diopters in maximum. Refraction results were related with age groups, using accommodative palsy medidne and measurement methods.
