The outcome of refractive error study among adults visiting optometry centers

Abstract

Background. The second cause of blindness is refractive error in the world. In Mongolia, 36% of blindness over 50 years is caused by refractive error. There are a few numbers of children refractive errors studies in Mongolia back ground is lack of research works in adults over 18 year old. Goal: To study and analyze the outcomes of refractive error over 18 years old adults visited some optometry centers of Ulaanbaatar city. Materials and methodology. Refractive data from 703 patients (1405 eyes) aged over 18 were collected from 5 optometry centers and eye clinics from January of 2019 to May 2019. We determine visual acuity, subjective and objective refraction. The statistical analysis of the study was investigated on SPSS 20 program. Result. Participants were from Ulaanbaatar city, others were from province. In this study myopia was the most common refractive error over 18 years. The prevalence of myopia was decreased with the age, the highest pick (44%) was from 18-29 years. Conclusion. Prevalence of refractive error of 703 participants from Ulaanbaatar city the emmetropia was 21 percent. Myopia was myopia was 57.2 percent, astigmatism was 16.7 percent, and hyperopia was 4.2 percent. The age and refractive error are statistically significant (р=0.001).
