Abstract

Introduction Vision play an important role during driving and many driving related injuries have been connected with visual problems. However, there is little information in profiling visual status among private vehicle drivers in rural area of Malaysia. The aim of this study is to determine visual function and binocular function status among private vehicle drivers in Klang Valley, Malaysia. Methods A descriptive cross-sectional study was conducted in the major towns within the Klang Valley of Malaysia. Participants were taken through a comprehensive eye examination after the administration of a structured questionnaire ResultsFifty private vehicle drivers (52% males and 48% females) participated in this study with mean age of 26±7 year. The mean of visual acuity and contrast sensitivity is 0.03±0.1 logMAR and 0.2±0.1 at 2.5% respectively. This study also found 2% of subject with colour deficiency and 4% of subjects had constricted visual field. The mean value for amplitude of accommodation, facility of accommodation, and stereopsis is 10.16±2.11 D, 8±1 cycle per minute (cpm), and 46 second of arc respectively. Based on chi square test, there is a significant association (p=0.018) between reduced binocular vision function and history of road traffic accident (RTA).
