Recurrent pterygium resection associated to fibrin membrane graft: report of two cases

Resseção do pterígio recorrente associada ao enxerto de membrana fibrina: relato de dois casos

ABSTRACT

We propose a novel surgical technique in cases of aggressive recurrent pterygium non-subsidiary of treatment with conjunctival autografts or antimetabolites. Two presented cases were treated with surgical excision and a sutured plasma rich in growth factors membrane (mPRGF) followed by rich in growth factors (PRGF) eye drops treatment. After surgery, dexamethasone, tobramycin and PRGF eye drops were prescribed for 6 weeks. After a 12-month and 3-year post-surgical follow-up respectively, treated eyes with mPRGF did not present relapse, and visual acuity improved in both cases. No ocular complications, pain, eye discomfort nor other symptoms were observed. The combined use of PRGF eye drops and mPRGF seems an effective and safe therapy for recurrent pterygium.
