Active clinical trials for "Glaucoma, Open-Angle"

The primary objective is to evaluate the Intraocular pressure reducing effect of Xalatan over 3 months. The secondary objective is to study the other efficacy parameters during treatment for 3 months

Diurnal fluctuations of intraocular pressure (IOP) and peripapillary retinal blood flow may have distinctive patterns in medically well-controlled open-angle glaucoma patients. In the results, we found a unique pattern, 'Latent asymmetric IOP', defined as the IOP which differs between the eyes only when placed in the supine position. Unique effects of this latent asymmetric IOP on Visual field and diurnal IOP fluctuations were studied.

To investigate the dose-response relationship of DE-104 ophthalmic solution in lowering intraocular pressure (IOP) in subjects with Primary Open-Angle Glaucoma or Ocular Hypertension

This study is designed to evaluate the safety and tolerability of Xalacom in patients with primary glaucoma

To investigate the effectiveness of the newer IOP-lowering therapies, as prescribed in normal clinical practice, in larger patient numbers. Patients will be assessed at baseline, at each follow-up visit (follow-up visits are variable as per physician discretion) and at final follow-up visit.

Glaucoma remains a disease with an unclear and complex underlying pathophysiology. Recently, researchers have emphasized not only intraocular pressure (IOP) or vascular dysregulation, but also translaminar pressure's (TPG) role in glaucoma (TPG=IOP-ICP). A higher TPG may lead to abnormal function and optic nerve damage due to changes in axonal transportation, deformation of the lamina cribrosa, altered blood flow, or a combination thereof leading to glaucomatous damage. However only invasive ICP measurements are available within the contemporary medicine. The ideas for non-invasive ICP measurement have been approached since about 1980. Most of the proposed technologies were based on ultrasound and were capable of monitoring blood flow in intracranial or intraocular vessels, cranium diameter, or acoustic properties of the cranium. Broad research has extended into sonography of optic nerve sheath and its relation with elevated ICP. However, most of these correlation-based methods had the same problem-the need of individual patient specific calibration. Seeking to measure absolute ICP values, researchers from Kaunas University of Technology created a non-invasive method, which does not need a patient specific calibration. The method is based on direct comparison of ICP value with the value of pressure Pe that is externally applied to the tissues surrounding the eyeball. Intracranial segment of ophthalmic artery (OA) is used as a natural sensor of ICP and extracranial segment of OA is used as a sensor of Pe. The special two depth transcranial Doppler (TCD) device is used as a pressure balance indicator when ICP = Pe. The aim of our study is to assess TPG in patients with primary open open-angle glaucoma (POAG). In addition the investigators want to measure ICP in patients with papilledema (PE) in order to compare them with glaucoma patients.

This study is a prospective, observational study of changing from any IOP-lowering treatment to a prostaglandin analogue-containing IOP-lowering medication for patients with Primary Open Angle Glaucoma (POAG) or Ocular Hypertension (OHT). The decision to change medications lies with the physician according to their standard practice.

The study will evaluate patients diagnosed with POAG or OHT who are switched to GANFORT® UD (unit dose of fixed combination bimatoprost and timolol) therapy for medical reasons in accordance with physician standard clinical practice. All treatment decisions lie with the physician.

An observational study comparing changing from an IOP-lowering treatment to a bimatoprost-containing IOP treatment in primary open-angle glaucoma (POAG) or ocular hypertension (OHT). Visits and treatment are per normal clinical practice.

The purpose of this study is to assess the long-term safety of the Glaukos® iStent® Trabecular Micro-Bypass Stent Model GTS100R/L in subjects previously enrolled in Glaukos Study GC-003.
