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.
