Pterygium is thought to be hyperaemia of fibrovascular tissue on to the cornea caused by ultraviolet radiation of sunlight. We observed a significantly high incidence of pterygia in welders who were exposed occupationally to excess ultraviolet radiation and found a close relationship between the incidence and the length of employment as a welder (r = 0.975, p less than 0.05). This study attempts to clarify the causative relationship between ultraviolet radiation and pterygia.
翼状胬肉被认为是由于阳光中的紫外线辐射导致纤维血管组织充血长入角膜。我们观察到职业性暴露于过量紫外线辐射的焊工中翼状胬肉的发病率显著较高，并发现发病率与焊工工作年限之间存在密切关系（r = 0.975，p < 0.05）。本研究试图阐明紫外线辐射与翼状胬肉之间的因果关系。
