Urrets-Zavalia Syndrome Following Trabeculectomy

ABSTRACT

PURPOSE: We report a case of Urrets-Zavalia syndrome with a fixed dilated pupil after an uneventful trabeculectomy.CASE SUMMARY: Trabeculectomy was performed on a 51-year-old male who had a history of recurrent uveitis in the left eye, with uncontrolled intraocular pressure despite maximally-tolerated medial therapy. There was no unexpected event during surgery. Topical 1% atropine was used for only 2 days after surgery. In the early postoperative period, 1% prednisolone and 0.3% ofloxacin were given four times a day, then gradually reduced. One month later, only 1% prednisolone was given once a day. Intraocular pressure in his left eye was well controlled from 8–14 mmHg after surgery. One month after surgery, the pupils remained dilated. There was no reaction to topical 2% pilocarpine and no relative afferent pupillary defect or posterior synechia.CONCLUSIONS: Our case, although rare, suggests that Urrets-Zavalia syndrome should be considered in patients with well-controlled intraocular pressure after uneventful trabeculectomy.
