PURPOSE To establish a new classification system for filtering blebs according to clinical morphologic parameters. The purpose of this classification system is to provide a uniform and objective assessment of bleb appearance and establish a framework system through which outcomes of filtration surgery may be better correlated to clinical morphology.

OBJECTIVES Hyperhomocysteinaemia is a well-known risk factor for venous thromboembolic disease (VTD). However, it is not clear whether homocysteine (Hc) itself or a related metabolite or a cofactor is primarily responsible for VTD. We carried out a case-control study to investigate whether vitamin concentrations that are involved in the Hc metabolism are(More)

Scar formation and fibrosis are the most common causes of ultimate glaucoma filtration surgery failure. The authors used Coulter counter, hexosaminidase, and 3H-thymidine assays to evaluate the effects of mithramycin, mitomycin, daunorubicin, and bleomycin on human subconjunctival fibroblast growth in tissue culture. Fifty percent inhibitory doses (ID50)(More)
OBJECTIVE To determine the frequency of dysphagia in CVA, its natural history and value as a risk factor of respiratory infection, malnutrition and death. PATIENTS AND METHODS A prospective study was made of 187 consecutive patients with cerebrovascular accidents (CVA). A standardized test for dysphagia was done during the first two days of the illness(More)
PURPOSE To evaluate the safety and efficacy of endoscopic cyclophotocoagulation in the treatment of refractory glaucomas. METHODS The preoperative and postoperative courses of 68 eyes of 68 patients who underwent endoscopic cyclophotocoagulation at our institution were retrospectively reviewed. Study patients had diverse forms of glaucoma, and most had(More)
OBJECTIVE This study aimed to ascertain whether the Optimed, Krupin, and Ahmed drainage devices function as valves that vary resistance depending on flow conditions to maintain pressure within a desired range. STUDY DESIGN Experimental study. INTERVENTION The three devices and a control cannula were submerged in fluid and perfused with balanced salt(More)
PURPOSE To report the intermediate-term results of the Baerveldt 250-mm2 Glaucoma Implant for treatment of adult glaucoma. DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS One hundred eight adult patients (108 eyes) with glaucoma who received a Baerveldt 250-mm2 Glaucoma Implant. INTERVENTION Implantation of the Baerveldt(More)
AIM To determine the aqueous humour concentration of the acid hydrolysis products of bimatoprost and latanoprost after a single topical dose of bimatoprost 0.03% or latanoprost 0.005% in humans. METHODS Randomised, controlled, double-masked, prospective study. 48 eyes of 48 patients scheduled for routine cataract surgery were randomised in an 8:2:2 ratio(More)
PURPOSE To evaluate the IOP-lowering efficacy of bimatoprost and travoprost for the treatment of glaucoma and ocular hypertension. METHODS Randomized, investigator-masked, parallel-group clinical trial. After completing a washout from all glaucoma medications, patients (n=26) were randomized to bimatoprost or travoprost for 6 months. Visits were at(More)
Utilizing a rapid colorimetric assay that relates cell number to cytoplasmic hexosaminidase activity, we conducted drug-induced cytotoxicity experiments on human ocular fibroblasts cultured from Tenon's capsule specimens. The effects of two different agents--dimethyl sulfoxide (DMSO) or mitomycin C--on the proliferation of human ocular fibroblasts were(More)
