We treated two patients in whom silicone oil pupillary block developed despite a patent inferior iridectomy. The clinical characteristics of this complication were a deep anterior chamber, specular reflexes from the iris surface, identification by biomicroscopy of aqueous trapped inferiorly in the vitreous cavity, and no convection currents in the anterior chamber. This complication may be prevented by early face-down positioning of the patient after the operation, and the avoidance of large, centrally located, inferior iridectomies. We recommend that the iridectomy be placed peripherally no larger than 2 mm and propose a new technique for breaking the silicone oil block, which was clearly successful in one of the patients.
我们治疗了两名患者，尽管进行了下虹膜切除术，但仍发生了硅油瞳孔阻滞。这种并发症的临床特征为前房深、虹膜表面有镜面反射、通过生物显微镜检查可发现玻璃体腔下方有被困的房水、前房内无对流。术后早期让患者俯卧位以及避免进行大的、位于中央的下虹膜切除术，可预防这种并发症。我们建议将虹膜切除术置于周边，直径不超过2毫米，并提出一种新的打破硅油阻滞的技术，该技术在其中一名患者中取得了明显成功。
