All across the world, glaucomatologists are adopting broader use of glaucoma drainage implants even as a primary surgical modality. To avoid tube exposure, which may predispose the eye to endophthalmitis, the implanted tube must be covered by a patch graft. However, these patch grafts also carry a high rate of progressive thinning and erosion, which is believed to result from the lack of cellul...

We present the case of successful repair of an exposed glaucoma drainage tube by cornea graft fixation with tissue adhesive, and without subsequent coverage by adjacent conjunctiva or donor tissues. Patient with history of keratoglobus with thin cornea and sclera, and phthisical contralateral eye, underwent three unsuccessful corneal grafts followed by Boston type 1 keratoprosthesis in the righ...

OBJECTIVE To evaluate the efficacy of the 175-mm2 Molteno3 implant in patients with nonneovascular glaucoma. METHODS A hospital-based, retrospective historical control comparative case series comparing results in the first 87 eyes to receive the 175-mm(2) Molteno3 implant with those in a control group of 115 eyes receiving the 274-mm(2) double-plate Molteno implant. RESULTS Success was defi...

Subconjunctival and subscleral fibrosis are the major causes of failure of filtering surgery. Antiproliferative agents have been successfully used to improve the long-term success of this surgery. Recent advancement in the field of glaucoma surgery has been the use of bioengineered, biodegradable, porous collagen-glycosaminoglycan matrix implant in the subconjunctival and/or subscleral space to...

PURPOSE This clinical study using a specific technique was carried out to determine the clinical effectiveness of zygomatic implants under an immediate loading protocol. MATERIALS AND METHODS All patients treated between May 2000 and October 2006 who received zygomatic implants were included in this retrospective analysis. All patients were treated using the same surgical and restorative prot...

AIM To evaluate the efficacy and safety of a stainless steel miniature glaucoma drainage device (Ex-PRESS R50) for the surgical treatment of primary open angle glaucoma (POAG) and cataract when combined with phacoemulsification. METHODS Clinical, prospective, multicentre, single treatment arm, non-randomised, non-masked study. The Ex-PRESS device was implanted at the limbus under a conjunctiv...

PURPOSE To evaluate the function of the blood aqueous barrier(BAB) in the eyes with silicone oil emulsification (SOE). METHODS Protein concentrations, expressed in albumin equivalents,were determined in aqueous humor of the eyes with SOE in 11 consecutive patients by means of proton nuclear magnetic resonance (1H NMR) spectroscopy. Correlations with various clinical factors were studied. RE...

BACKGROUND One barrier to patient adherence with chronic topical glaucoma treatment is an inadequate amount of medication available between prescription refills. We examined the self-reported prevalence of early exhaustion of glaucoma eye drops prior to a scheduled refill, and associated risk factors. METHODS This cross-sectional survey was performed at a University-based clinical practice. G...

BACKGROUND To report the results of the repair of conjunctival erosions resulting from glaucoma drainage device surgery using collagen-glycosaminoglycane matrices (CGM). METHODS Case series of 8 patients who underwent revision surgery due to conjunctival defects with exposed tubes through necrosis of the overlying scleral flap and conjunctiva after Baerveldt drainage device surgery. The defec...
