Corneoscleral graft in Mooren's ulcer: a case report

INTRODUCTION Mooren's ulcer is a rare disorder of unknown etiology that is refractory to treatment. It can affect not just the cornea but also the scleral tissue and can involve both eyes. CASE PRESENTATION We report a case of a 74-year-old man with a history of bilateral and malignant Mooren's ulcer. The patient had undergone an exenteratio bulbi of the left eye because of the perforation of a Mooren's corneal ulcer. The perforated Mooren's corneal ulcer also presented in the right eye and involved the adjacent scleral tissue. It was decided to perform a corneal-scleral graft to preserve the anatomical integrity of the eye. CONCLUSION This report highlights how a corneal-scleral graft followed by systemic and local immunosuppressive treatment should be considered in monocular patients with malignant Mooren's ulcer where there is serious damage to the corneal and scleral tissue.
