Routine binocular examination of young Taiwanese adults as a predictor of visual behavior performance

Abstract

Abstract Background Morgan and Scheiman’s Optometric Extension Program (OEP) expected binocular vision findings have longstanding use in optometry. With technological advances, the demands and standards of binocular function have changed. This study aimed to investigate which binocular visual functions can effectively predict visual behavior performance. Methods Participants aged 15–24 years were recruited from two colleges and two universities. After completing the CSMU-Visual Behavioral Performance questionnaire (CSMU-VBP, with four components: near work, visual perception, visual comfort, and whole-body balance), participants were divided into symptomatic and asymptomatic groups based on questionnaire findings (cutoff: 11.5, NBI blur > 15, NBI break > 17.5, NBI recovery > 13, NPC − 0.5, gradient AC/A [minus] > 2.25, NPC < 4.75). Conclusions The mean values of binocular visual function among young Taiwanese adults were statistically different from traditional normative values. Further research is required to confirm whether these findings reflect impaired binocular vision or stringent criteria. Assessments of binocular visual function, especially binocular accommodation sensitivity, are crucial in routine optometric examination.
