摘要

目的：分析臺灣之蘭嶼島上達悟族中老年族群之翼狀贅片流行率。材料與方法：四十歲以上居民以隨機方式採樣，並以裂隙燈等檢查。結果：共有兩百四十九人接受檢查，共計一百零一名男性，一百四十八名女性。自四十歲至八十七歲，平均年齡58.54歲(standard deviation, SD±12.95)。男性平均60.09歲，女性平均57.49歲。翼狀贅片之整體發生率為53.01% (95%CI: 39.18%-66.84%)，平均每人有1.03片翼狀贅片。中年族群平均發生率為42.5% (95%CI: 28.79%-56.20%)，平均每名患者0.79片。老年族群發生率為71.91% (95%CI: 59.45%-84.37%)，平均每名患者1.47片。翼狀贅片發生率於中或老年族群中並無性別之發生差異，發生型態以鼻側為好發位置。達悟族各年齡層男女之翼狀贅片發生比並無男女差異。結論：整體而言，達悟族的翼狀贅片發生率與其他原住民族相近，且均較臺灣本島人民為高，且發生率均隨年齡增加而攀升，可能與緯度及紫外線曝曬及戶外生活型態有關。

Objective: To survey the incidence of pterygium among middle-aged and elderly aborigines of the Tao tribe of Orchid Island, Taiwan. Materials and Methods: Inhabitants aged 40 years and above were examined with a slit-lamp at random selection. Results: A total of 249 participants were enrolled into this survey, including 101 men and 148 women. Their ages ranged from 40 to 87 years. The mean age of the total population was 58.54 years (standard deviation, SD±12.95); 60.09 years in the men (SD±12.99) and 57.49 years in the women (SD±12.86). Of the population surveyed, the total prevalence rate of pterygium was 53.01% (132/249) (95%CI: 39.18%-66.84%), which increased with age. There was a total of 257 pterygia among the 132 patients. The average number of pterygia per person was 1.03(257/249) and this increased with age; varying from 0.79 (126/160) among the middle- aged group (40 to 64 years old) to 1.47 (131/89) in the elderly group (65 years old and above). There was no significant difference between genders. Pterygium occurred with predominance on the nasal side of the ocular surface. Conclusions: The high prevalence of pterygium (53.01%) among the middle-aged and elderly population of the Tao tribe in Orchid Island may be related to the latitude, ultraviolet exposure and lifestyle.
