Transscleral Cyclophotocoagulation for the Treatment of Uncontrolled Glaucoma in a Boston Keratoprosthesis Type II Patient

Abstract

Postoperative endoscopic cyclophotocoagulation (CPC) for the treatment of glaucoma in patients with Boston keratoprosthesis type II (BKPro II) was first described in 2017 by Poon et al. (Endoscopic cyclophotocoagulation for the treatment of glaucoma in Boston keratoprosthesis type ii patient. J Glaucoma. 2017 Apr;26(4):e146-9). As we do not have this device, we present a case of transscleral CPC (TSCPC), in a BKPro II patient who had graft versus host disease and developed uncontrolled glaucoma. We dissected plane by plane to expose the bare sclera and performed the procedure as traditionally described. We concluded that this is a safe, controlled, and effective option in this patient population where the glaucoma treatment options are very limited. To the best of our knowledge, this is the first case report to describe the surgical technique of TSCPC in a BKPro II patient.
