| description | Purpose:This study was to determine the positive and negative range of accommodation and vergence measures of drivers and non-drivers based on refractive error. Method: Fifty-two of UiTMPuncakAlam students with range of age from 20 to 25 years old were recruited in this cross sectional study. Pilot study wasconducted to establish the intra reliability among four examiners participated in
this study. The subjects need to pass all the inclusion criteria in the screening procedures before proceed into data measurement procedures.For the range of
accommodation, NRA were measured first by using plus lens, follow with PRA using minus lens. For the vergence range, we measured using step vergence technique using prism bar. NFV were measured using base-in prism, followed with PFV by using base-out prism. For the subjects who drive, they were brought to measure their driving setting, which include the distance of eyes to the dashboard and rear mirror using the same car. Results: Kruskall-Wallis test revealed statistical significant difference of NRA between emmetropic drivers and myopic drivers with p value 0.017. NRA between myopic drivers and myopic non-drivers also had shown statistical significant difference with p value of 0.026. There were no statistical
significant differences of the positive range of accommodation and vergence measures of drivers and non-drivers based on refractive error. The distance from
dashboard and rear mirror also showed no statistical significant difference based on refractive error, with p value of 0.225 and 0.326 respectively.Conclusion: NRA of
emmetropic drivers was significantly lower compared to myopic drivers. However, other parameters tested were not significantly difference which could be due to the
absence of driving task in this study. Future study might have to look into the involvement of driving task on the range of accommodation and vergence measures. |
