NCT ID: NCT00799994 Completed - Glaucoma Clinical Trials

Does Lowering Eye Pressure Affect the Results Obtained From Objective Visual Field Testing?

Start date: October 2004
Phase: N/A
Study type: Observational

A study to determine whether a patient's range of vision test results improve after their eye pressure is lowered by 30% or more by testing on a new machine called the Accumap and how to learn how much the Accumap's results change from one test to another within the same person. The investigators believe that Multifocal VEP readings (Accumap)(and therefore visual function and ganglion cell function) improve after acutely lowering intraocular pressure.

NCT ID: NCT00799682 Completed - Dry Eye Disease Clinical Trials

Exploratory Study Comparing Signs and Symptoms in Patients With Ocular Hypertension or Glaucoma Using Xalatan R® or Travatan Z®

Start date: October 2008
Phase: Phase 4
Study type: Interventional

The purpose of this study is to determine if there is a difference in the ocular signs and symptoms of subjects' eyes using Xalatan® 0.005% versus Travatan Z® 0.004% based on the outcome of subject assessment and clinical assessment in patients with Ocular Hypertension or Glaucoma with mild to moderate dry eye at baseline in accordance with the Oxford Grading Scale.

NCT ID: NCT00798694 Completed - Glaucoma Clinical Trials

How Similar Are Changes to the Surface of the Eye When Two Different Glaucoma Eye Drops Are Used?

Start date: November 2008
Phase: Phase 4
Study type: Interventional

To determine whether one glaucoma eye drop is less likely to cause changes to the surface of the eye (conjunctiva) than another. The two different prostaglandins are Xalatan and Travatan Z.

NCT ID: NCT00796198 Not yet recruiting - Glaucoma Clinical Trials

Effects of Cosopt on IOP and on Ocular Diastolic Perfusion Pressure

Start date: December 2008
Phase: Phase 4
Study type: Interventional

Hypothesis: Studies suggest that patients with low diastolic velocity and high resistivity index in the ophthalmic artery had more progressive visual fields, the investigators hypothesize therefore that addition of Cosopt to Latanoprost could improve ocular diastolic perfusion pressure (ODPP). Objective: To evaluate the effects of Cosopt on ODPP in patients not adequately controlled with latanoprost alone.

NCT ID: NCT00794170 Completed - Glaucoma Clinical Trials

Interactive Study to Increase Glaucoma Adherence to Treatment

I-SIGHT
Start date: August 2008
Phase: N/A
Study type: Interventional

Study participants who receive the I-SIGHT intervention will have higher rates of glaucoma treatment compliance (e.g., medication-taking and refill compliance, return for clinical follow-up) and more positive eye health outcomes at 12-month follow-up than participants who receive the control group intervention.

NCT ID: NCT00792259 Completed - Glaucoma Clinical Trials

Topcon 3D OCT-1000 Optical Coherence Tomography System

Start date: October 2008
Phase:
Study type: Observational

The purpose of this clinical protocol is to perform a comparison of Retinal and Retinal Nerve Fiber Layer (RNFL) thickness measurements between the Topcon 3D-1000 and the identified predicate device. In addition, this protocol performs a comparison of the thickness measurement results from images collected and analyzed with the Zeiss Stratus OCT to images collected with the Zeiss Stratus OCT and imported into the Topcon 3D OCT-1000 StratusViewer for analysis.

NCT ID: NCT00788762 Active, not recruiting - Glaucoma Clinical Trials

Myocilin Variations and Familial Glaucoma in Taxiarchis

Taxiarchis
Start date: August 2007
Phase:
Study type: Observational

Taxiarchis, a small village in Northern Greece with 1060 inhabitants, was considered to have a surprisingly high incidence of glaucoma. This isolated population located on Mount Holomondas appeared to be enriched for familial glaucoma. Based upon the high reported incidence of glaucoma in Taxiarchis and previous findings of the Thr377Met myocilin mutation in the Greek population,the investigators undertook a community-based study to determine if this variant was present in this village.

NCT ID: NCT00788541 Terminated - Ocular Hypertension Clinical Trials

A Dose-Volume Study of a Treatment for Elevated IOP Due to Open-Angle Glaucoma or Ocular Hypertension

Start date: December 2008
Phase: Phase 2
Study type: Interventional

The purpose of this study was to assess the effects of total volume and total dose on the safety and intraocular pressure-lowering efficacy of Anecortave Acetate Suspension (3 mg and 48 mg) in 0.5 mL and 0.8 mL volumes when administered by anterior juxtascleral depot (AJD) for the treatment of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension.

NCT ID: NCT00773877 Recruiting - Clinical trials for Primary Open Angle Glaucoma

Comparison of Retinal Nerve Fiber Layer (RNFL) Thickness Measurements by Time-Domain and Spectral-Domain OCT In Glaucoma Patients

Start date: October 2008
Phase: N/A
Study type: Observational

Measurement of RNFL thickness by OCT is at a cornerstone for the correct diagnosis and monitoring of progression of glaucomatous optic neuropathy. Spectral domain technology has enabled better reproducibility with better axial resolution in the measurement of RNFL thickness. A comparative study among Stratus, Cirrus and RT-View will enable clinicians to determine differences among various instruments.

NCT ID: NCT00773123 Recruiting - Clinical trials for Primary Open Angle Glaucoma

Efficacy of Retinal Nerve Fiber Layer (RNFL) / Ganglion Cell Layer Thickness Ratio by RT-View Utilizing Spectral -Domain Technology as a Diagnostic Predictor of Glaucoma.

Start date: October 2008
Phase: N/A
Study type: Observational

RT-View utilizes spectral domain technology to assess both RNFL and ganglion cell layer thickness. This study aims to correlate visual field defects in patients with glaucoma to both RNFL and ganglion cell layer thickness.
