Extracapsular surgery has a high frequency of capsular rupture or disinsertion in patients with pseudoexfoliation syndrome. Irido-phakodonesis is one of the factors that suggests this complication. Irido-phakodonesis acts as an 'all or nothing' mechanism, as it does not appear until there is a certain degree of zonular lesion. We carried out a study on 330 eyes with pseudoexfoliation, relating irido-phakodonesis to 31 clinical signs. The results showed that irido-phakodonesis is related to cataracts, degree of mydriasis, presence of glaucoma, atrophy of the pupilar pigmentary ruff, and uniform pigmentation of the trabecular meshwork. These results suggest that the signs which indicate the existence of zonular lesion during extracapsular surgery, include poor dilation, the presence of glaucoma and pigmentary alterations, whilst the pseudoexfoliation material deposited in the anterior segment does not appear to have a bearing on this complication.
在假性剥脱综合征患者中，囊外手术发生晶状体囊破裂或脱位的频率较高。虹膜晶状体震颤是提示该并发症的因素之一。虹膜晶状体震颤作为一种“全或无”机制，直到出现一定程度的悬韧带病变才会出现。我们对330只患有假性剥脱的眼睛进行了一项研究，将虹膜晶状体震颤与31种临床体征相关联。结果表明，虹膜晶状体震颤与白内障、散瞳程度、青光眼的存在、瞳孔色素皱褶萎缩以及小梁网均匀色素沉着有关。这些结果表明，在囊外手术期间提示存在悬韧带病变的体征包括散瞳不佳、青光眼的存在和色素改变，而沉积在前房的假性剥脱物质似乎与该并发症无关。
