Abstract

 

Purpose: To compare spectrum of autorefraction and retinoscopy with subjective acceptance between rural and urban school going children.

Materials and Methods:  A total of 100 Children between 6-16 years of age were included in this study (50 rural 50 urban). Findings of autorefraction and retinoscopy with subjective acceptance were calculated and compared between the two groups.

Results: Out of 100 children 22% were in the age group of 6-8 years, 30% in the age group of 9-11 years with a frequency of  30% and 34% in the age group of 12-14 years and 14% of  ≥15 years. The mean age was 11.2 years. Dry autorefractometer over corrects refractive error in comparison to subjective acceptance. In our study of wet autorefraction and subjective acceptance myopia has mean of -2.27 with subjective acceptance of 2.03 whereas in hypermetropia has mean of 2.81 with acceptance 2.52 in right eye. In comparison of dry retinoscopy with subjective acceptance myopia of right eye has mean of -0.99 with SD-2.03 and hyperopia of 3.49 with SD 2.52. In comparison of wet retinoscopy with subjective acceptance which shows P value of <0.05 which is clinically insignificant.

Conclusion: We concluded from this study that autorefractometer over estimates refractive errors but there was no significant difference between wet retnoscopy and subjective acceptance. So according to this study we suggest use of cycloplegic retnoscopy with subjective acceptance in determining refractive errors in children.
