BACKGROUND
Surgeons often notice unexplained dilation of the pupil following an uncomplicated intra-ocular surgery. No definite line of treatment has been proposed for managing Urrets-Zavalia syndrome (UZS). The authors have previously documented the results of surgical pupilloplasty and have outlined this modality of treatment for cases with UZS.
PURPOSE
To highlight the aspect of development of UZS post-operatively in the eyes following an intra-ocular surgery.
SYNOPSIS
The video highlights the aspect of prevalence of the persistently dilated pupil that is non-responsive to topical miotics. Apart from associated glare, these cases often have raised intra-ocular pressure because of appositional closure of the anterior chamber angle. Surgical pupilloplasty pulls the iris tissue centrally, eventually releasing the mechanical blockage and often breakage of the peripheral anterior synechias as demonstrated by intra-operative gonioscopy and anterior segment optical coherence tomography.
HIGHLIGHTS
Performing a surgical pupilloplasty can resolve the UZS, and timely intervention can also prevent the development of secondary glaucoma because of fallback of the iris tissue on the structures of the anterior chamber angle.

背景
外科医生经常在简单的眼内手术后注意到瞳孔不明原因的扩大。对于治疗 Urrets-Zavalia 综合征（UZS），尚未提出明确的治疗方案。作者之前已经记录了手术瞳孔成形术的结果，并为 UZS 病例概述了这种治疗方法。
目的
强调眼内手术后 UZS 发展的方面。
概要
该视频突出显示了术后瞳孔持续扩大且对局部缩瞳剂无反应的情况。除了相关的眩光外，这些病例通常由于前房角的贴壁性关闭而导致眼内压升高。手术瞳孔成形术将虹膜组织拉向中央，最终释放机械性阻塞，并且经常通过术中房角镜检查和眼前节光学相干断层扫描来破坏周边前粘连。
重点
进行手术瞳孔成形术可以解决 UZS，及时干预也可以防止由于虹膜组织 fallback 在前房角结构上而导致的继发性青光眼的发展。
