Correlation of Visual Acuity Screening in Preschool Children Between Personal Computer Software Jaeb Visual Acuity Screener (JVAS) and Tumbling E

Abstract

Purpose Tumbling E is commonly used for visual acuity screening for children and adults. Currently, AAPOS recommends a computerized visual acuity-based screening application JVAS with standardized optotype and illumination, quick examination, simple procedure that needs relatively small space and no need specialized training for the examiner. The aim of this study was to determine agreement value of visual acuity screening in preschool children between using computerized application JVAS and tumbling E. Methods This was a correlation study between JVAS and tumbling E. Subjects selected by multistage random sampling and met the inclusion criteria were examined using JVAS and tumbling E at intervals of 10 minutes in the same room by a refractionist. The difference between the results of the two charts was determined with chi-square McNemar test and the agreement value were analyzed using Kappa index method. Results Kappa index 0.296 showed a poor agreement in visual acuity screening in preschool children between using computerized application JVAS and tumbling E, and showed statistically significant difference (p=0.00). There was a moderate agreement in the age group of 4 years with the results of Kappa index 0.459 and p = 0.500. Conclusions There was no agreement in visual acuity screening in preschool children between using computerized application JVAS and tumbling E. Visual acuity screening of preschoolers should use the age-appropriate tools with normal threshold values based on age-appropriate visual development.
