XEN-related hypotonous maculopathy from iatrogenic cyclodialysis cleft treated with argon laser gonio-cyclopexy

Abstract

We present a previously undescribed case of a persistent hypotony maculopathy secondary to an iatrogenic cyclodialysis cleft created during XEN-45 gel stent insertion. We present this case as a further analysis of theKarimi et alcase of cyclopexy by the corresponding surgeon. Following right XEN-45 implantation, our patient developed immediate and persistent postoperative hypotony for 4 weeks. Gonioscopy revealed a small cyclodialysis cleft at the 1–2 o’clock position. The cyclodialysis cleft was sealed with direct gonioscopic argon laser cyclopexy. Two months after laser treatment and total of 6 months post XEN-45 insertion, right eye visual acuity returned to 6/4 with intraocular pressure 11 mm Hg without any glaucoma medication. Here, we present details of the non-invasive safe and successful management of hypotony maculopathy secondary to the cleft using Argon laser gonio cyclopexy, with no requirement of return to theatre.
