Management of perforated peripheral ulcerative keratitis (PUK-Mooren’s ulcer) with iris prolapse study in two cases

Abstract

Aim: The aim of this study was to describe the management of two cases of perforated peripheral ulcerative keratitis (PUK-Mooren’s ulcer) with iris prolapse by using dried sclero-corneal patch graft and subsequently replacing donor sclero-corneal patch graft. Methods: After sectoral conjunctival resection, ulcer margin excision, and prolapsed iris excision, preserved dried sclero-corneal tissue is fashioned, and patch grafting is done as an emergency. After getting the donor sclerocorneal rim, it was again fashioned (matching the size and removal of Descemet’s membrane) and replaced the dried scleral patch graft followed by a bandage contact lens. Results: Eleven to 16 months after their initial evaluation, these patients still had some useful vision and selfsatisfaction. Conclusion: A dried sclera-corneal patch graft could be a satisfactory option in the temporary management of perforated PUK with iris prolapse until donor tissue is available. This patch graft prevents hypotony, posterior synechiae, and secondary glaucoma.
