A Case of Bilateral Choroidal Effusion after XEN Gel Stent Implantation

Abstract

Purpose: This study aimed to describe a rare case of bilateral choroidal effusion following a XEN45 implantation. Case Report: An 84-year-old man with primary open-angle glaucoma underwent uneventful ab interno XEN45 device implantation in the right eye. The immediate postoperative period was complicated by hypotony and serous choroidal detachment, which were treated and resolved using steroids and cycloplegic drops. Eight months later, the fellow eye underwent the same surgery, which was followed by choroidal detachment that required transscleral surgical drainage. Conclusions: This case highlights the importance of a careful postoperative follow-up and a timely intervention in the context of XEN45 implantation, and suggests that choroidal effusion in one eye may be a risk factor for choroidal effusion in the other eye when undergoing the same type of surgery.
