Ciliary and iris block glaucoma in aphakic and phakic eyes is characterized by the accumulation of aqueous humor in the vitreous cavity causing an increase in vitreous volume, a flattening of the anterior chamber, and an elevation of intraocular pressure. As vitreous blocks the space between the ciliary body and the iris or lens, respectively, an anterior vitrectomy via the pars plana is the logical surgical approach. This operation was performed in one phakic and 15 aphakic eyes with so-called pupillary block. The anterior chamber retained a normal depth in each case. Post-operatively the vitreous was found to be completely removed from the posterior chamber and the epiciliary space, rendering a free communication between the ciliary body and the posterior and anterior chamber. Early surgery in aphakic eyes with a flat anterior chamber resulted in a prompt normalization of intraocular pressure, whereas eyes with a block duration of over 4 weeks were at high risk of developing a secondary outflow resistance probably due to chronic angle closure.
无晶状体眼和有晶状体眼的睫状环阻滞性青光眼及虹膜阻滞性青光眼的特征是，玻璃体内房水积聚导致玻璃体容积增加、前房变浅以及眼压升高。由于玻璃体分别阻塞了睫状体与虹膜或晶状体之间的间隙，经睫状体平坦部进行前部玻璃体切除术是合理的手术方法。该手术在1例有晶状体眼和15例无晶状体眼（所谓的瞳孔阻滞）中实施。在每种情况下，前房均保持正常深度。术后发现玻璃体已从后房和睫状体上间隙完全清除，使睫状体与后房和前房之间实现了自由连通。无前房的无晶状体眼早期手术可使眼压迅速恢复正常，而阻滞持续时间超过4周的眼睛发生继发性流出阻力的风险较高，这可能是由于慢性房角关闭所致。
