Rapid deterioration of Mooren’s ulcers after conjunctival flap: a review of 2 cases

Abstract

Abstract Background Conjunctival flaps are a widely used treatment for numerous corneal ulcers that are caused by microorganismal infections. However, whether it can be performed on immune-mediated corneal ulcers is controversial. Case presentation We present two cases of Mooren’s ulcer that were treated using conjunctival flap in an attempt to prevent further corneal perforation at their local hospital. A rapid acceleration in ulcer progression was observed after a conjunctival flap was applied. Ultimately, the two patients underwent corneal transplantation, which required the postoperative use of topical immunosuppressants and resulted in a final cure. In the current report, we also discussed this incorrect surgical choice via a review of conventional interventions that are used to treat Mooren’s ulcer. Conclusions These two cases demonstrate that keratoplasty combined with topical immunosuppressants is effective in treating Mooren’s ulcer. Application of conjunctival flaps or autografting could promote progression of ulceration in Mooren’s ulcers.
