Active clinical trials for "Glaucoma, Open-Angle"

Lowering of the pressure in the eye (intraocular pressure, IOP) is the only proven treatment for Primary Open-angle Glaucoma (POAG). However, even effective reduction of IOP by pharmacological or surgical means does not always change the course of the disease or prevent the onset of glaucoma. Some people with POAG also suffer from Obstructive Sleep Apnoea (OSA), an increasingly common sleep disorder which is known to affect heart and blood vessels, and may contribute to glaucoma progression. OSA is treated with Continuous Positive Airway Pressure (CPAP); however using this type of breathing support may raise IOP. This study aims to establish whether a short-term application of CPAP in awake subjects leads to an increase in IOP. Patients with treated POAG, patients with newly diagnosed untreated POAG and control subjects without glaucoma will be included. CPAP will be applied at several different pressure levels for a total of 2 hours during which IOP and ocular perfusion pressure (OPP) will be measured. If CPAP is shown to raise IOP or alter OPP it could be necessary to assess available alternative treatment options for OSA.

The purpose of this study is to assess whether an educational intervention will have a positive effect on patients' ability to properly administer eye drops. The investigators predict that the educational intervention will have a positive impact on the efficacy, safety, and efficiency with which patients administer their eye drops.

To evaluate the efficacy of once daily dosing with SPARC's novel ophthalmic formulation of bimatoprost compared with Lumigan 0.01% in subjects with open-angle glaucoma or ocular hypertension.

The purpose of this study is to evaluate the long-term safety and performance of the ARGOS-IO system in patients with Primary Open Angle Glaucoma (POAG)

The objective of this study is to evaluate the effectiveness (Intra-Ocular Pressure lowering) and safety of Direct Selective Laser Trabeculoplasty (DSLT) in ethnic Chinese subjects with Primary Open Angle Glaucoma or Ocular Hypertension.

Combined cataract + trabectome surgery is a surgery designed to help lower the intraocular pressure (pressure in the eye) and hopefully reduce the need for topical drops, progression of glaucoma, and/or further glaucoma surgeries. The purpose of this study is to assess whether using pilocarpine, a medication which is FDA approved to induce miosis, (in other words cause the pupil to constrict or become smaller) provides additional benefit to the success of Trabectome and cataract surgery.

The primary objective of this research is to compare the efficacy of trabecular minimally invasive glaucoma surgery (MIGS) devices (iStent vs iStent Inject vs Hydrus) for intra ocular pressure (IOP) and anti-glaucoma medication reduction in open angle glaucoma.

This study evaluates the possible acute changes in peripapillary blood flow after instillation of antiglaucoma medications in patients with primary open angle glaucoma (POAG), normal tension glaucoma (NTG), or ocular hypertension (OHTN) using Optical Coherence Tomography (OCT) angiography.

The purpose of this study is to evaluate the safety and performance of the ARGOS-IO system in patients with POAG and indicated cataract surgery.
