Abstract

Objective:To evaluate the accuracy and effectiveness of noncycloplegic & cycloplegic refraction using Gimbalscope (GS) A Frugal smartphone Retinoscope; compared with Streak Retinoscopy (SR) & Autorefractometer (AR) in children and adolescents. Method:This randomized trial included 300 eyes of children and adolescents.Non cycloplegic and cycloplegic refractive measurements were obtained GS, SR and AR. The Spherical(S), Cylindrical(C), Axis of Cylinder(A) & Spherical equivalent(M) were statistically compared. Measurement discrepancies from SR, GS & AR were compared using ANOVA and ROC curve analysis. Results: Compared with SR and AR, measurements obtained before & after cycloplegia with GS showed excellent reliability. No significant statistical difference was found between the 3 methods. This was one of the first studies done which used a smartphone-aided retinoscope to compare results with AR & SR. It was found to be useful for teaching purposes for residents and optometrists alike.
