Clinical Evaluation of the Effect of Mitomycin-C in Re-Operation for Primary Open Angle Glaucoma

Abstract: The aim of the study was to evaluate the effect of mitomycin-C (MMC) in a second antiglaucoma operation after failure of the first operation. We assessed 46 patients (26 male, 20 female, mean age 64.2 years) with high intraocular pressure (IOP) (mean 32.4 +/- 5.2 mmHg) despite previous trabeculectomy (Tr-Ec) one to three years earlier and topical or systemic medical treatment. All patients underwent a second Tr-Ec and were randomly divided into two groups: group A, 24 patients, underwent a second Tr-Ec with MM… Show more

“…59 Although many studies have evaluated tube shunts in refractory glaucoma (e.g., neovascular glaucoma, uveitic glaucoma, conjunctival scarring), 1825 limited information exists about the use of these devices in eyes with non-refractory glaucoma and no prior ocular surgery. Valimaki and colleagues reported IOP reduction to 15.4 mm Hg with the Molteno3 implant (Molteno Ophthalmic Limited, Dunedin, New Zealand) in 38 patients with primary open angle glaucoma and pseudoexfoliative glaucoma.…”

“…Existem alguns fatores que aumentam o risco de falência da cirurgia antiglaucomatosa, tais como: raça negra, idade abaixo de 40 anos, pseudofacia ou afacia, trabeculectomia prévia não funcionante, glaucoma secundário a uveíte e neovascular (1)(2)(3)(4) , uso de mióticos por mais de 18 meses (4) e simpaticomiméticos por mais de 6 meses (4) . Com o aparecimento dos agentes moduladores da cicatrização, o 5-fluorouracil (5FU) e a mitomicina-C (MMC), houve melhora do prognóstico cirúrgico das trabeculectomias, especialmente nos pacientes com mais de um fator de risco (2)(3) .…”

“…A menor toxicidade corneal e o uso de uma aplicação única intraoperatória tornou a MMC mais popular e utilizada em olhos com pior prognóstico cirúrgico, quando comparada com o 5FU (3,5) . Segundo um artigo que avalia risco e sucesso, somente 26% dos pacien-tes com 2 ou mais fatores de risco citados obtiveram pressão intra-ocular menor que 16 mmHg quando foram submetidos a cirurgia sem antimetabólicos (4) . Outro estudo demonstrou que 85% dos pacientes operados com MMC obtiveram sucesso cirúrgico enquanto que apenas 50% alcançaram tal eficácia sem MMC (6) outro autor obteve taxa ainda menor sem o uso de MMC que foi de 29% (7) .…”

“…However, anti-metabolite use may increase the risk of complications such as ocular hypotony, wound leakage and infection. 27,28 Microtrabeculectomy, usually performed under local anaesthesia, is a less invasive variant of the trabeculectomy procedure which is gaining popularity. Reverse trabeculectomy, deep sclerectomy and viscocanalostomy are other novel procedures, which are currently being evaluated in the treatment of POAG.…”
