摘　　要：目的　调查海南省翼状胬肉的患病率 ,探讨翼状胬肉与地域、气候等环境条件及性别、种族等人群因素间的关系。方法　采用随机、整群抽样方法 ,抽取海南省东方市和昌江县 14个村的7990例受检对象进行检查 ,并根据翼状胬肉的形态及其头部所在位置进行分级检查记录。结果　在7990例受检者中 ,翼状胬肉患者 6 2 8例 ,患病率为 7 86 %。汉族 5 30 3例中 ,翼状胬肉患者 439例(8 2 8% ) ;黎族 2 6 87例中 ,翼状胬肉患者 189例 (7 0 3% ) ,两者比较差异有显著性 (χ2 =3 897,P =0 0 48)。男性患者 2 6 6例 (6 43% ) ,女性患者 36 2例 (9 40 % ) ,男性患病率较女性低 (χ2 =19 85 2 ,P =0 0 0 1)。翼状胬肉在眼部多呈对称性分布。结论　海南省翼状胬肉患病率高与该地区的地理位置、气候条件有关。海南省汉族翼状胬肉的患病率高于黎族 ,女性高于男性。在各年龄组中 ,翼状胬肉患病率随年龄增长而增加。Objective To explore the relationship between pterygium and environmental condition, such as area and weather, and human factors, such as sex and race, through the prevalence survey of pterygium in Hainan Province. Methods As a sample, all villagers in 14 villages were chosen by random sampling from all the rural villages of Dongfang and Changjiang Counties, the pterygium was examined and their pterygia were recorded and graded according to the shape and the location of the head of pterygium. Results In 7 990 villagers examined, there were 628 cases with pterygium, prevalence being 7 86% and including 439 cases (8 28%) in 5 303 Han people and 189 cases (7 03%) in 2 687 Li people. The difference of the prevalence between Han and Li nationality was significant (χ 2=3 897, P = 0 048). There were 266 male cases (6 43%) and 362 female cases (9 40%). The prevalence in male was less than that in female (χ 2=19 852, P = 0 001). The distribution of the pterygium in eyes was symmetrical. Conclusion The prevalence of pterygium in Hainan is higher than that in other provinces of China. It may be related to the geographic location and weather condition. In Hainan Province, the prevalence of pterygium in Han nationality is higher than that in Li nationality and in female higher than that in male. The increase of the prevalence of pterygium may be related to the increase of age.
