A case of Mooren ulcer with corneal perforation following cyclophotocoagulation for glaucoma

Purpose: To report a case who developed Mooren ulcer following cyclophotocoagulation resulting in corneal perforation. Case: A 64-year-old female developed elevation of intraocular pressure (IOP). She had received surgery for cataract and glaucoma 16 years before. She had been treated by us since 4 years before. Findings: Corrected visual acuity was 0.7 right and 0.05 left. The right eye was Pseudophakic. Myopia of - 9.0D was present in the right eye and - 18.0D in the left. Both eyes showed wide chamber angle. The right eye showed IOP of 40 mmHg. She refused surgery and the right eye was treated by transscleral cyclophotocoagulation. The right cornea showed erosion one month later and thinning 3 months later. The right eye was diagnosed with Mooren ulcer after exclusion of viral infection and collagen disease. The right cornea showed spontaneous perforation with collapse of the eyeglobe 8 months later. She refused keratoplasty and was treated by exenteration. Conclusion: This case illustrates that transscleral cyclophotocoagulation may be followed by corneal ulcer as a major complication.
