Summary

The aim of this study was to verify whether prostaglandin analogue (PA) eye drops influence the retinal thickness of glaucomatous patients undergoing trabeculectomy (TRAB) surgery. We selected eyes of patients with glaucoma with surgical indication for TRAB who were using PA eye drops and without previous retinal alterations, from the Centro de Referência em Oftalmologia (CEROF) from the Federal University of Goiás and Fundação Banco de Olhos de Goiás (FUBOG). Patients were divided into 2 groups: the study group (SG) and the control group (CG). In the CG, the PA was suspended between 30 and 60 days before the preoperative exams were performed (maximum of 15 days before surgery for both groups). All patients included were submitted to various eye exams before the procedure, and postoperatively on 3 occasions: 1 to 3 days ("PO1"), 6 to 9 days ("PO7") and 27 to 30 days ("PO30") after surgery.

PROCEDURE

Trabeculectomy surgery

The Trabeculectomy aims to create a permanent drainage outflow channel for the aqueous humor, connecting the anterior chamber to the sub-Tenon's space, using mitomycin C consisted of opening the conjunctival base of the fornix and applying mitomycin C 0.4 mg/ml for 2 minutes. The trabeculectomy techniques require controlled outflow of aqueous humor through a sclerostomy and a partial-thickness scleral flap to form a subconjunctival bleb. The protected strength of the flap, with or without sutures, and the strength of the episcleral tissue determine the final IOP.
