Active clinical trials for "Glaucoma"

The purpose of the study is to determine the relationship of the intraocular pressure patterns recorded during 2 sessions using Triggerfish, before and after elective laser peripheral iridotomy in angle closure glaucoma patients.

The objective of this clinical investigation is to determine the most effective drug concentration(s) of BOL-303259-X in the reduction of IOP in order to support further clinical development of an appropriate dose with regard to efficacy, and ocular and systemic safety.

Retisert implant is an effective therapy for controlling inflammation in patients with non-infectious posterior uveitis. One of the major complications of this device is the development of elevated intraocular pressure (IOP) following implantation in 60% of patients. Glaucoma filtering is required in over 30% of patients at 2 years. Anecortave acetate (AA) has been shown to reduce steroid induced elevated IOP. The purpose of this study was to evaluate the ability of prophylactic anterior juxtascleral depot administration of AA to prevent this Retisert induced elevated IOP.

This study aim to determine the feasibility of using a virtual reality (VR) headset (HTC Vive) to test the visual field. The VR headset test will be compared to a conventional visual field test, using the Humphrey Field Analyzer. The investigators will include 10 healthy patients without visual field defect, 10 patients with early glaucomatous visual field defect, and 10 patients with advanced visual field defect. Each patient will perform the conventional test twice and the VR headset test 4 times, divided in 3 visits within a 2 month period. The results of the tests (sensitivity thresholds) will be compared. The investigators hypothesize that the results of the conventional and VR tests will be similar.

There is a lack of evidence on the impact of switching from a combined preserved anti-glaucoma regimen to a preservative-free (PF) one, while employing sufficiently robust OSD metrics. The investigators have therefore carried out a single center, prospective, crossover investigation to compare the 6-month effect of switching well controlled open-angle glaucoma patients with at least moderate glaucoma therapy-related ocular surface disease from preserved to triple preservative-free therapy with and without cyclosporine 0.1% dosed in the evening.

The purpose of this study is to learn if breathing nitrous oxide (also known as "laughing gas") changes the pressure in a person's eyes. Some patients who need regular eye exams to measure their eye pressure often need to be put to sleep with medicine in order to complete the eye exam. Some of these medicines are known to cause changes in a person's eye pressure. Because of this, such medicines are avoided if the eye doctor needs to measure the patient's eye pressure. One medicine that is frequently used to put patients to sleep is nitrous oxide. No one really knows what effect nitrous oxide might have on a persons' eye pressure. The investigators are interested to see if nitrous oxide causes an increase, decrease, or no change in eye pressure. The investigators also want to investigate if there is a difference in the effects of nitrous oxide on eye pressure between males and females. Understanding these effects of nitrous oxide is important because during such eye exams, the eye doctor uses the pressure measurements to make important decisions about treatment and surgery options for the patient. The investigators hypothesize that the use of inhaled nitrous oxide (N2O) will result in a decrease in IOP in healthy volunteers. The investigators aim to determine the magnitude and duration of change, if any, in IOP caused by inhalation of N2O, and to assess if the gender of the patient has a role in this effect.

The purpose of this investigation is to study the safety and tolerability of SENSIMED Triggerfish, a soft contact lens-based device intended to continuously record relative changes in intraocular pressure (IOP). The investigation enrols glaucoma patients and glaucoma suspects. All subjects receive two 24-hour recording sessions with the device in an ambulatory setting and at weekly interval. The level of discomfort in the study eye after 24 hours and side effects are the main endpoints of the investigation.
