Retrospective Review of Xen Gel Stent Implantation With Open vs. Closed Conjunctiva Approach

Retrospective Review of Xen Gel Stent Implantation With Open vs. Closed Conjunctiva Approach

To measure surgical success of open vs closed conjunctiva with Xen implantation.

This retrospective, single-arm multicenter study included >100 eyes (>100 patients) with glaucoma refractory to medical therapy. All surgeries were performed by two groups of surgeons at Johns Hopkins University and the sub-investigator group at New York University. Group 1: Xen with open conjunctiva for positioning and application of mitomycin. The Xen was placed through the sclera either ab-interno or ab-externa. Group 2 had Xen placed ab-interno or ab-externa (trans conjunctival), but the conjunctiva was not opened for positioning or application of mitomycin-C.

Success rates will be determined based on need for re-intervention and intraocular pressure control.

Inclusion Criteria:

• Require surgery for uncontrolled glaucoma

Exclusion Criteria:

• None
