Recurrent cystoid macular edema following Boston keratoprosthesis type-II implantation: A treatment option

Abstract

A 68-year-old woman with end-stage Stevens–Johnson syndrome developed cystoid macular edema (CME) 3 months following Boston keratoprosthesis type II (KPro-II) implantation and treated with single-dose injection of triamcinolone acetonide (TA) in the inferior peribulbar region. After 14 days, CME resolved completely, and she regained 20/30 vision. Seven months later, she developed recurrent CME. She was again treated with a similar peribulbar injection of TA. CME was resolved completely after 2 weeks with full visual and anatomical recovery. Here, we present a case of recurrent CME following KPro-II implantation responsive to peribulbar injection of TA, which may be the only effective treatment option.
