Active clinical trials for "Glaucoma"

The purpose of the study is to demonstrate that the IOP-lowering efficacy of DuoTrav APS, dosed once-daily in the morning, is non-inferior to that of DuoTrav, dosed once-daily in the morning.

Prostaglandin analogues have not been used in the treatment of neovascular glaucoma because of suspicious lack of efficacy. This study aims at assessing the effect of travoprost on neovascular glaucoma.

The purpose of this study is to evaluate the efficacy of changing to DuoTrav® (Travoprost 0.004%/Timolol 0.5%) from prior prostaglandin analogue or beta-blocker monotherapy in Russian glaucoma patients with open-angle glaucoma or ocular hypertension whose intraocular pressure (IOP) is uncontrolled while on their current treatment.

Sleep apnea is characterized by repetitive episodes of decreased or interrupted airflow in the upper airways during sleep. Obstructive sleep apnea syndrome (OSAS) is the most common sleep-related breathing disorder and is characterized by repeated partial or complete upper airway collapse, gasping episodes, daytime sleepiness and fatigue. Once suspected, the diagnosis is made on the basis of anamnesis and a polysomnography (PSG) using the so-called respiratory disturbance index (RDI) to grade OSAS. Standard therapy consists of continuous positive airway pressure (CPAP) during sleep to prevent upper airway collapse. The association between OSAS and glaucoma has been extensively studied, although a few reports have been non-confirmatory. OSAS has been associated with reduced ocular blood flow, leading to hypoxia and hypercapnia, and as such, may represent a risk factor for glaucomatous optic neuropathy. OSAS has also been related to loss of nycthemeral rhythm of intraocular pressure (IOP). In addition, CPAP has been reported to increase IOP when used during nighttime. The purpose of this study is to investigate how IOP varies in time, particularly during sleep in OSAS patients with or without glaucoma, and if the IOP variations are associated with the use of CPAP. IOP fluctuations will be monitored with SENSIMED Triggerfish®, a portable investigational device using a contact lens sensor that monitors the IOP fluctuation continuously over 24-hours.

To determine whether medical reduction of intraocular pressure prevents or delays the onset of glaucomatous visual field loss and/or optic disc damage in ocular hypertensive participants judged to be at moderate risk for developing open-angle glaucoma. To produce natural history data to assist in identifying patients at most risk for developing open-angle glaucoma and those most likely to benefit from early medical treatment. To quantify risk factors for developing open-angle glaucoma among ocular hypertensive individuals.

This prospective, single-arm clinical multicenter study intends to measure normal structural parameters of the optic nerve head, the peripapillary retinal nerve fiber layer, and the macula using the Heidelberg Spectralis OCT device. This study is conducted in Hispanic descent volunteers. The main goal of the study is to provide the range of these structural parameters in normal eyes. The study will include at least 240 normal volunteers.

The purpose of this study is to determine the relationship between Intraocular Pressure (IOP) fluctuations of glaucoma patients as recorded with an IOP-sensing contact lens (SENSIMED Triggerfish®), during two 24-hour periods after selective laser trabeculoplasty (SLT) for routine treatment of glaucoma.

To investigate whether the new applanation tonometer (EyeCheck monitor) can provide intraocular pressure (IOP) measurements comparable to those of traditional tonometers such as the Goldmann applanation tonometer and the Tonopen.

This study is a prospective comparative, randomized, single center study to assess agreement and precision of the P200TE in comparison to the predicate device in normal subjects, subjects with glaucoma, and subjects with retinal disease.

This clinical trial is designed to investigate the performance of SENSIMED Triggerfish® during 24-hour continuous IOP fluctuation monitoring, defined as the number of valid recording intervals over the 24-hour period. The investigation will recruit male and female patients older than 18 years and diagnosed with glaucoma and treated with tafluprost in both eyes. 20 subjects will be enrolled in the study. Patients will be considered enrolled in the study upon signature of informed consent. A screening visit and one 24-hour IOP fluctuation monitoring session during a 36-hour hospitalisation, are planned for each patient.
