XEN Gel Stent to Treat ICE Syndrome: 4 Cases.

UNLABELLED

PRéCIS:: This case series reports safe, effective implantation of XEN gel stents to treat iridocorneal endothelial (ICE) syndrome. The stents continue to function well and have not been occluded by membranes or peripheral anterior synechiae, but continued follow-up is necessary.

PURPOSE

ICE syndrome-related glaucoma is often refractory to medical treatment, and traditional surgical treatment has lower success rates than typical for other types of glaucoma. We present a series of patients who were treated with XEN gel stent implantation.

PATIENTS AND METHODS

Retrospective case series of 4 patients with ICE syndrome who underwent XEN with subconjunctival mitomycin C injection.

RESULTS

Average preoperative intraocular pressure was 28.5 mm Hg on 3.8 glaucoma medications, and average postoperative intraocular pressure was 10.5 mm Hg on 1.0 medication. No patients required return to the operating room for additional procedures over an average of 6.9 months of follow-up. One patient had shallow anterior chamber that resolved with conservative management. Another had shallow anterior chamber that resolved with anterior chamber reformation with viscoelastic and developed nonappositional choroidal effusions that had resolved at most recent follow-up of 7 months after surgery. No XEN implants have been occluded by membrane formation or peripheral anterior synechiae.

CONCLUSIONS

XEN is a safe and effective option for surgical management of ICE syndrome-related glaucoma. Further follow-up surveillance is necessary.
