The ocular anatomic features, pupil-blocking force, status of angle synechia closure and positivity of provocative tests were compared between the primary chronic angle closure glaucoma (PCACG) and primary acute angle closure glaucoma (PAACG) by ultrasonic biometry, computerized image processing technique of the anterior ocular segment, gonioscopy and provocative tests. The studies showed that the anterior chamber depth of PAACG was shallower than that of PCACG, the pupil-blocking force of PAACG was stronger than that of PCACG, the status of angle synechia closure of PCACG was mainly creeping synechia closure and the positivity of mydriasis test after iridectomy was much higher (37.93%) in PCACG than that (11.43%) in PAACG. These facts suggested that the mechanisms of the angle closure of more than half of PCACG cases be multiple, besides the mechanism of pupillary block. Therefore, the authors emphasize that the pupillary block must be eliminated as well as the other mechanisms for the treatment of PCACG. The criteria of diagnosis and principles of management of PCACG were proposed.
通过超声生物测量、眼前节计算机图像处理技术、前房角镜检查和激发试验，比较原发性慢性闭角型青光眼（PCACG）和原发性急性闭角型青光眼（PAACG）的眼部解剖特征、瞳孔阻滞力、房角粘连关闭状态及激发试验阳性率。研究显示，PAACG的前房深度比PCACG浅，PAACG的瞳孔阻滞力比PCACG强，PCACG的房角粘连关闭状态主要为渐进性粘连关闭，且PCACG虹膜切除术后散瞳试验阳性率（37.93%）远高于PAACG（11.43%）。这些事实表明，超过半数的PCACG病例房角关闭机制除瞳孔阻滞外还有多种机制。因此，作者强调，治疗PCACG时必须消除瞳孔阻滞及其他机制。提出了PCACG的诊断标准和治疗原则。
