虹膜睫状体炎或称前葡萄膜炎为眼科常见疾患,每因后遗瞳孔闭锁、继发性青光眼、并发性白内障等等而导致失明,应引起重视。虹膜睫状体炎的病因十分复杂,尤以内因性者为然,临床上常不易确定,且目前的分类亦未臻完善。Woods氏对内因性葡萄膜炎有多年的研究,认为仍有不少问题值得探讨。就病因而论,过去学者多偏重于结核与梅毒。自1912年Billings氏引导病灶感染理论以来,一些病因未明的葡萄膜炎多归究于病灶。1954年Alvaro氏的统计87.5％是由病灶所致,而1955年Bennett氏的统计则竟无一例是由病灶引致的。1957年Stanworth与 Iridocyclitis or anterior uveitis is a common ophthalmopathy, each cause of pupil atresia, secondary glaucoma, cataracts and so cause blindness, should pay attention. The etiology of iridocyclitis is very complex, especially for those with internal causes, clinically often difficult to determine, and the current classification is not perfect. Woods’s internal uveitis has many years of research, that there are still many problems worth exploring. On the etiology, in the past scholars tend to focus on tuberculosis and syphilis. Since 1912, Billings’s guide to the theory of focal infection, some of the etiology of unknown uveitis more focus on the lesion. 87.5% of Alvaro’s statistics in 1954 were caused by lesions, and none of Bennett’s statistics in 1955 was caused by lesions. 1957 Stanworth and
