To find out the prevalence of pingueculum and pterygium among commercial motorcyclists in Benin City, Nigeria and to note any associated or risk factors.
A prospective, cross sectional, case control study.
A local Government Area (Oredo) and University of Benin Teaching Hospital, Benin City, Nigeria.
One hundred and forty four commercial male motorcyclists in motorcycle parks in the local Government area and a control group of 114 male indoor workers.
Presence of pterygium or pingueculum.
One hundred and forty four male motorcyclists formed the subjects of this study. The age range was 18 to 65 years with a mean age of 34.9 +/- 8.0 years. The total number of motorcyclists with pingueculum was 37 with 26 bilateral cases, 63 eyes were involved. The prevalence rate was 25.7%. Pterygium was present in 18 patients including 12 bilateral cases making a total of 30 eyes. The prevalence rate was 12.5% The total number of indoor workers with pingueculum was 24 and it was present in 46 eyes. The prevalence rate was 21.05%. Pterygium was present in 12 eyes of nine persons in the control group and the prevalence rate was 7.9%. There was no association between the duration of work as a commercial motor cyclist and the presence of a pterygium or a pingueculum. The usage of a hat/cap was found to have a protective effect as motorcyclists who do not wear hats are more likely to develop pingueculum than those who wear them. The use of glasses and hats together was found to be protective against the development of pingueculum and pterygium in this study.
The prevalence rate of 12.5% of pterygium and 25.7% of pingueculum in commercial motorcyclists in this study is quite high when compared with that of the controls. The wearing of face caps/hats was found to have a protective effect. They should be educated about the importance of wearing protective goggles and caps/brimmed hats.
了解尼日利亚贝宁城商业摩托车骑手睑裂斑和翼状胬肉的患病率，并记录任何相关因素或危险因素。
一项前瞻性横断面病例对照研究。
尼日利亚贝宁城的一个地方政府区域（奥雷多）和贝宁大学教学医院。
地方政府区域摩托车停放处的144名商业男性摩托车骑手以及114名男性室内工作者组成的对照组。
翼状胬肉或睑裂斑的存在情况。
144名男性摩托车骑手构成了本研究的对象。年龄范围为18至65岁，平均年龄为34.9±8.0岁。患有睑裂斑的摩托车骑手总数为37人，其中双侧病例26例，累及63只眼。患病率为25.7%。18例患者患有翼状胬肉，其中双侧病例12例，共30只眼。患病率为12.5%。室内工作者中患有睑裂斑的总数为24人，累及46只眼。患病率为21.05%。对照组9人中有12只眼患有翼状胬肉，患病率为7.9%。作为商业摩托车骑手的工作时长与翼状胬肉或睑裂斑的存在之间没有关联。发现戴帽子/便帽有保护作用，因为不戴帽子的摩托车骑手比戴帽子的更易患睑裂斑。在本研究中，发现同时使用眼镜和帽子可预防睑裂斑和翼状胬肉的发生。
与对照组相比，本研究中商业摩托车骑手翼状胬肉患病率为12.5%、睑裂斑患病率为25.7%相当高。发现戴面罩/帽子有保护作用。应向他们宣传佩戴防护眼镜和帽子/宽边帽的重要性。
