PURPOSE To investigate the efficacy and safety of mitomycin C (MMC)-augmented deep sclerectomy with implant (DSCI) in primary open-angle glaucoma (POAG) and exfoliation glaucoma (ExG) patients. METHODS A total of 68 eyes of 68 patients with POAG and ExG were enrolled consecutively to undergo DSCI with MMC (0.4 mg/ml for 2 min). The intraocular pressure(More)
In glaucoma, extensive pathological changes occur in the trabecular meshwork (TM) and juxtacanalicular tissue of the chamber angle. Aqueous humor drainage is disturbed due to the accumulation of extracellular matrix (ECM) material in the outflow system. Matrix metalloproteinases (MMPs) remodel ECM material and, thus, they may have a role in regulating(More)
PURPOSE Phospholipase A2 (PLA2) is a growing family of lipolytic enzymes that play a key role in various biological processes including general lipid metabolism, membrane homeostasis, and in diseases such as atherosclerosis, arthritis, and acute pancreatitis. Oxidative stress as well as inflammation may be associated with glaucoma pathogenesis. Therefore,(More)
PURPOSE To retrospectively compare the efficacy of deep sclerectomy in the treatment of primary open-angle glaucoma (POAG) and exfoliation glaucoma (ExG). METHODS Deep sclerectomy with either collagen or hyaluronate implants was performed in 31 eyes (45%) with POAG and 38 eyes (55%) with ExG. Pre- and postoperative intraocular pressure (IOP) was recorded,(More)
New straightforward applications of new biopolymers are needed in glaucoma surgery. The aim of this study was to compare biocompatibility of three biomaterials in rabbit eyes after deep sclerectomy; a collagen implant (AquaFlow) represented the "gold standard". A blend of 85:15 poly(L-lactide-co-glycolide) and 70:30 poly(L-lactide-co-1,3-trimethylene(More)
PURPOSE Chronic conjunctival inflammation, caused by various reasons, for example long-term use of topical drugs and/or their preservatives, affects the outcome of glaucoma surgery by interfering with wound healing. Matrix metalloproteinases (MMPs) remodel extracellular matrix (ECM) and are involved in the wound healing process. This study was designed to(More)

PURPOSE Conjunctival specimens from primary open-angle glaucoma (POAG), exfoliation glaucoma (ExG) patients and controls were histologically analysed for oxidized low-density lipoprotein (ox-LDL), lipid and calcium aggregates. Our goal was to use them as biomarkers of oxidative stress and inflammation and to evaluate their correlation with glaucoma and(More)
