Virtual Reality Based Binocular Vision Therapy Game for the Management of Amblyopia

Abstract

Aim: To develop a novel virtual reality (VR)-based binocular vision therapy game for newlinethe management of amblyopia. newline newlineMethodology: Questionnaires were developed and validated to understand the newlineawareness, attitude and acceptance of digital screen-based binocular vision therapy newline(DSBBVT) among parents and eye care practitioners. The two questionnaires newlineunderwent the process of development through focus group discussion, face validity, newlineand statistical test of reliability. The results drawn from the two questionnaires were newlineconsidered in finalizing the features of novel game applications for the management of newlineamblyopia. The VR game application (app) was developed by a software developer newlinewith the input given by the researcher. Technical and clinical testing for the visual newlinetargets of Gabor s patch used in the game app was completed before utilizing the app newlinein the clinical setup. newline newlineThe efficacy of the game app was tested by having one group play this game for 20 newlineminutes a day for three months along with occlusion therapy. The other group of newlinesubjects continued the occlusion therapy for 3 months. The visual functions like visual newlineacuity, stereopsis, contrast sensitivity, fusion status, visual perceptual skills and reading newlinespeed were compared with the baseline clinical values among both the groups after newlinethree months of therapy. newline
