To estimate the prevalence of pterygium and its influence on visual acuity in aged population of Doumen County, southern China.
A population-based survey was conducted in Doumen County, the rural area of southern China. Twenty-seven sample units were selected by random sampling. The prevalence and severity of pterygium and it-related low visual acuity were analyzed.
Of the total 4 762 individuals aged 50 years or over, 4 214 were examined. The prevalence of pterygium was 33.01% in subjects aged 50 years or above. There was a significantly higher prevalence in female (35.70%) than in male (29.70%, P = 0.025). The prevalence of pterygium in age groups of 50s, 60s, 70s and 80s years old is 33.98%, 36.40%, 30.73% and 25.40%, respectively. Most of the pterygia were located in the nasal side (93.31%) of cornea, and only 6.69% in the temporal side. 0.92% of the eyes had visual acuity less than 0.32, which were directly caused by pterygia.
The current survey suggests that the pterygium is one of the most common diseases of external eye in the population aged 50 years and above. It is still leading to the impairment of visual acuity in the rural area.
评估中国南方斗门县老年人群中翼状胬肉的患病率及其对视力的影响。
在中国南方农村地区的斗门县进行了一项基于人群的调查。通过随机抽样选择了27个样本单位。分析了翼状胬肉的患病率、严重程度及其相关的低视力情况。
在4762名50岁及以上的个体中，4214人接受了检查。50岁及以上人群中翼状胬肉的患病率为33.01%。女性患病率（35.70%）显著高于男性（29.70%，P = 0.025）。50多岁、60多岁、70多岁和80多岁年龄组中翼状胬肉的患病率分别为33.98%、36.40%、30.73%和25.40%。大多数翼状胬肉位于角膜鼻侧（93.31%），颞侧仅占6.69%。0.92%的眼睛视力低于0.32，这是由翼状胬肉直接导致的。
本次调查表明，翼状胬肉是50岁及以上人群中最常见的外眼疾病之一。在农村地区，它仍然导致视力损害。
