NR-1000F Auto Refractometer application in children refractive errors evaluation

Abstract

The aim of this research is to determine the frequency of refractive errors in individuals aged 7 to 18 years using the Nikon Auto Refractometer NR- 1000F.

Methods. We examined 1000 of 7-18 year-old children. Children were divided into three age groups: I group from age 7 to 9 years, II group from age 10 to 13 years and III group from age 14 to 18 years. The Nikon Auto Refractometer NR- 1000F was used to determine the refractive errors.

Results. Prevalence of emetropia was overall 3.5 % in the 7-18 years olds children. Prevalence of myopia was overall 37.9 % and increased from 16.7% in the I-st age group to 50.8% in the III-rd age group. I-st degree of myopia was prevail in all age groups.Hypermetropia was found in 58.6% and decreased from 81.2% in the I-st age group to 45.3% in the III-rd age group. I-st degree of hypermetropia was the most common refractive error in all age groups.

Conlusion. The prevalence of emetropia was 3.5%, of myopia was 37.9 % and of hypermetropia was 58.6%.I-st degree myopia and I-st degree hypermetropia was the most common refractive errors in all age groups.
