Outcomes of a Tenon Patch Graft for Corneal Perforations in Resolving Infectious Keratitis.

Abstract

Purpose: To report the outcomes of a Tenon patch graft (TPG) in sealing corneal perforations in cases with resolving infectious keratitis.

Methods: This retrospective interventional study was conducted at a tertiary eye care center. All patients who underwent a TPG for corneal perforations because of clinically or/and microbiologically diagnosed infectious keratitis between 2021 and 2023 were included. The surgical technique was consistent with that used in noninfective etiology. Out of 100 cases undergoing a TPG during the same period, 15 eyes of 14 patients had corneal perforations secondary to infectious keratitis.

Results: The etiological profile included bacterial keratitis in 8, viral and fungal keratitis in 3, and Pythium keratitis in 1 eye of 15 eyes. One patient had bilateral infectious keratitis after refractive surgery. The perforations were central in 7 and paracentral in 8 eyes. Successful restoration of tectonic integrity at 1 month was achieved in 14/15 eyes (93%). One patient had a repeat perforation at 3 weeks postoperatively, which was managed with a cyanoacrylate glue application. Infection control was achieved in all cases with adjunctive topical antimicrobial therapy.

Conclusions: A TPG is a viable option for restoring globe integrity in corneal perforations encountered in resolving infectious keratitis.
