PURPOSE To compare the effectiveness of Humphrey Matrix perimetry, GDx VCC, Stratus OCT, and retinal nerve fiber layer (RNFL) photography using the Heidelberg Retina Angiograph 1 (HRA1) for early glaucoma detection. DESIGN Cross-sectional comparative study. PARTICIPANTS Seventy-two primary open-angle glaucoma patients with early-stage visual field(More)
To evaluate the long-term intraocular pressure (IOP) control of trabeculectomy and triple procedure (cataract extraction by phacoemulsification, intraocular lens implantation and trabeculectomy), 1,542 eyes of 900 patients with primary open angle glaucoma (POAG) or chronic primary angle closure glaucoma (CPACG) were included. When success was defined as an(More)
Agmatine, a primary polyamine and potential neuromodulator, exhibits a high affinity to the alpha2-adrenergic receptor as well as imidazoline receptors. As alpha2-adrenergic receptor agonists display positive ocular hypotensive effects, we assessed whether agmatine effectively lowers intraocular pressure (IOP) using a chronic ocular hypertensive rat model.(More)
We compared visual field indices calculated by Humphrey matrix perimetry (HMP) and Humphrey perimetry (HP) in 62 early glaucoma patients and 587 normal subjects. Reliability indices, except for the false positive rate, were smaller when using HMP. Mean deviation (MD) and pattern standard deviation (PSD) calculated by HMP correlated with those by HP, but MD(More)
BACKGROUND In light of concern about the possible relation between the extensive clinical use of prostaglandin analogues and the development of retinal disorders such as cystoid macular edema, this study investigated the influence of topical application of bimatoprost 0.03% on macular thickness and volume in glaucoma patients with phakic eyes. METHODS A(More)
AIMS The aim of this study was to compare the prophylactic effect of brimonidine 0.2% versus brimonidine Purite 0.15% on intraocular pressure (IOP) increase after Nd:YAG laser posterior capsulotomy. METHODS In this prospective, double-masked, randomized, controlled study, 106 patients (106 eyes) who underwent Nd:YAG laser posterior capsulotomy were(More)
