目的调查四川省泸州市40岁及以上人群中翼状胬肉的患病率，探讨翼状胬肉的发病与环境、年龄、性别等因素的关系。方法采用多级分层整群随机抽样的方法抽取泸州市6个社区共7478人受检对象进行调查，对翼状胬肉进行诊断和分级，计算翼状胬肉患病率。结果在7478人受检对象中，共发现翼状胬肉患者401例，患病率为5．36％；其中男性受检对象3123人，男性患者187例，患病率为5．99％；女性受检对象4355人，女性患者214例，患病率为4．91％。男性患病率明显高于女性患病率（X^2=4．133，P=0．042）。患病率随年龄的增加而升高。结论泸州市翼状胬肉患病率与泸州地理环境有关。男性患病率高于女性，可能与泸州地区男性作为家庭主要劳动力接触危险刺激因素的机会较女性增加有关。
