Abstract

Purpose: To report a surgical approach combining scleral patch graft and tenonplasty for successful management of refractory Pseudomonas scleritis following pterygium removal with mitomycin C application. Case Report: A 75-year-old diabetic woman with a history of prior pterygium excision and mitomycin C application developed infectious necrotizing scleritis caused by Pseudomonas aeruginosa. Owing to progression of scleritis despite medical management, the patient underwent surgery. Intraoperatively, extensive scleral ischemia was noted. Therefore, debridement of the necrotic tissue, scleral graft, tenonplasty to bring blood vessels to the ischemic sclera, and amniotic membrane transplantation were performed. Postoperatively, no signs of ischemia or recurrence of infection were observed. During 6 months of follow-up, the patient achieved complete restoration of the globe integrity with a non-inflamed ocular surface. Conclusion: Through restoration of blood supply to the ischemic sclera, tenonplasty is an effective adjunctive procedure in addition to conventional scleral patch graft for the treatment of refractory Pseudomonas scleritis associated with ischemia. © 2018 Journal of Ophthalmic and Vision Research.
