作者对最近6年期间的所有虹膜囊肿患者作了仔细观察和随访。观察过程中,发现两大类虹膜囊肿(原发和继发)的区别愈趋明显。原发性虹膜囊肿没有明显原因(自发性),继发性者则有手术损伤、非手术损伤或局部长时间用缩瞳剂等因素。原发性虹膜囊肿(尤其色素上皮囊肿)的绝大多数很少进展或引起视力损害。这个发现与某些权威人士观点不一致,继发性虹膜囊肿则常长大,导致严重并发症,如炎症及青光眼。由于继发性虹膜囊肿在文献上已引起足够重视,本文只报告原发性虹膜囊肿62例。关于原发性虹膜囊肿,文献上至今缺乏大组 The authors carefully observed and followed up all patients with iris cysts over the last 6 years. During the observation, it was found that the difference between the two major types of iris cysts (primary and secondary) became apparent. There are no obvious causes (spontaneous) in primary iris cysts, surgical injuries secondary to non-surgical injuries or partial long-term use of miotic agents and other factors. The vast majority of primary iris cysts (especially pigmented epithelial cysts) rarely progress or cause visual impairment. This finding is inconsistent with the opinion of some authorities that secondary iris cysts often grow, leading to serious complications such as inflammation and glaucoma. As the secondary iris cyst has been given enough attention in the literature, this report only 62 cases of primary iris cysts. On the primary iris cysts, the literature lacks a large group
