Filter by:The purpose of the study is to assess the safety, tolerability, and IOP effects of RO5093151 following 7 days of topical ocular treatment in patients with primary open angle glaucoma or ocular hypertension.
The study aims to further understand glaucoma pathogenesis and progression by utilizing enhanced depth imaging optical coherence tomography to visualize and measure lamina cribrosa in vivo and segmentation technology to accurately delineate and measure boundaries of the retinal layers. Investigators will elaborate further on key concepts of lamina cribrosa thickness and trans-synaptic degeneration.
Evaluate sensitivity and specificity of NOVA-DN visually evoked potentials (VEP) protocol and new software method (Corda) for glaucoma detection using optical coherence tomography (OCT) images to differentiate between normal subjects and glaucoma suspects.
To evaluate the safety and efficacy of Levobetaxolol in Chinese patients with glaucoma.
The main objective of this study is to quantify vision parameters in subjects with concentric visual field constriction, and this in relation to the display on virtual reality goggles. More specifically: - The maximum brightness value for visual comfort (THRESHOLD_MAX) - The minimum value of the perceptible light contrast in low light perceptible (THRESHOLD_MIN) - The speed of light change adaptation in the range [THRESHOLD_MAX-THRESHOLD_MIN] and [THRESHOLD_MIN-THRESHOLD_MAX].
The water drinking test (WDT), is a predictive test that has been used to detect primary open angle glaucoma and recently has been demonstrated as a predictor of the diurnal tension curve. Clinically accurate provocative tests for asymptomatic eyes with shallow anterior chambers and narrow angles are highly desirable to detect patients prone to angle closure glaucoma. The aim of this pilot study is to evaluate the possible role of water drinking test in patients with narrow angles who are scheduled for prophylactic laser iridotomy.
The purpose of the present study is to compare rates of glaucomatous optic neuropathy in professional wind versus non-wind instrument players in the Philadelphia Orchestra. A secondary objective is to evaluate intra-ocular pressure and choroidal thickness of wind instrument players under variable playing conditions.
The main goal of the study is to compile a normative database for the Neuro Optic Vision Assessment (NOVATM) Pattern Electroretinogram (PERG) and Flash Electroretinogram (FERG) modules. This normalization intends to be included in a probabilistic analysis protocol to allow NOVATM PERG/FERG users to identify patients with results outside the normal ranges.
Wills Eye Hospital Glaucoma Research Center will conduct a 1-year prospective study to assess the ability of a Short Duration Transient Visual Evoked Potential (SD- tVEP) and a Steady-State Pattern electro-retinogram (PERG) vision testing system to detect visual dysfunction in patients with ocular hypertension. The study aims to assess the reversibility of retinal ganglion cell (RGC) dysfunction after administering intraocular pressure (IOP) lowering treatment. The investigators hypothesize that SD-tVEP and PERG testing will help develop better treatment for glaucoma patients by increasing understanding of the physiological relationship of IOP and RGC in glaucomatous injury.
The aim of this study was to evaluate structural and functional improvement after lowering intraocular pressure (IOP) in patients with glaucoma using Spectral Domain Optical Coherence Tomography (SD-OCT), Visual Field (VF) testing, and Visual Evoked Potential (VEP).
