Visual functions of commercial drivers in relation to road accidents in Nigeria
Objective : To determine the effects of the visual functions on the
occurrence of road traffic accidents (RTA) amongst commercial drivers
in Ife central local government area (LGA) of Osun state of Nigeria.
Design : A cross-sectional study. Settings : Four major motor parks
located at Ife Central LGA. Materials and Methods : Of the estimated
270 commercial drivers in the four major parks of the LGA, 215
consecutive drivers were interviewed and had their eyes examined.
Structured questionnaires were administered by an ophthalmologist.
Results: The prevalence of visual impairment (visual acuity < 6/18)
in the better eye without correction was 3.3% ± 2.4 and there was
a significant association between uncorrected visual acuity impairment
in the better eye and RTA ( P = 0.0152). Refractive error was seen in
8.4% of the drivers, but none of these wear corrective glasses. Visual
field defect, abnormal stereopsis and color vision impairment did not
have any significant association with RTA. Conclusion : Poor visual
acuity is strongly associated with RTA amongst Nigerian commercial
drivers as opposed to visual field defect, abnormal color vision and
stereopsis. A significant proportion of visual impairment was due to
uncorrected refractive errors
