目的:探讨眼科疾病在重型车辆驾驶员中的患病率。方法:在2004-11/2006-09期间选取驾驶员(实验组)和非驾驶员(对照组)各200例进行眼科全面检查包括视力和后房,使用自动验光仪检查屈光不正。结果:根据检查结果,屈光不正的患病率实验组为21.5%,对照组为31.3%(P<0.05).实验组中常见类型为近视散光(8.3%),而对照组为单纯近视(12.8%)。实验组色觉障碍的患病率为2.2%,对照组为2.8%,两组总的患病率为2.6%。结论:大多数驾驶员没有具备良好的视力,其中屈光不正可以影响行驶安全。

AIM:To investigate the frequency of eye disorders in heavy vehicle drivers. METHODS:A cross-sectional type study was conducted between November 2004 and September 2006 in 200 drivers and 200 non-driver persons. A complete ophthalmologic examination was performed,including visual acuity and dilated examination of the posterior segment. We used the auto refractometer for determining refractive errors. RESULTS:According to eye examination results, the prevalence of the refractive errors was 21. 5% and 31. 3% in study and control groups respectively ( P < 0. 05) . The most common type of refraction errors in the study group was myopic astigmatism ( 8. 3%) while in the control group simple myopia( 12. 8%) . Prevalence of dyschromatopsia in the drivers, control group and total group was 2. 2%,2. 8% and 2. 6% respectively. CONCLUSION:A considerably high number of drivers are in lack of optimal visual acuity. Refraction errors in drivers may impair the traffic security.
