Active clinical trials for "Glaucoma"

Investigation of the reading parameters and fixation behavior in patients with different ocular diseases (age-related macular degeneration, glaucoma, diabetic maculopathy, epiretinal membrane) and healthy subjects. In addition, fixation analysis and retinal sensitivity measurements will be done with a microperimeter in each subject.

Glaucoma is a common, potentially blinding pathology, threatening patients' autonomy and quality of life. The main aim of treatment is to lower intraocular pressure (IOP) in order to slow nerve fiber loss as much as possible, leading to alterations in the visual field and even reduced visual acuity. To achieve this drop in pressure, there are, of course, hypotonizing eye drops, trabeculoplasty with Laser Selecta (SLT) or filtering surgery (trabeculectomy, deep non-perforating sclerectomy, insertion of drainage devices). Laser Selecta specifically targets pigmented trabecular meshwork cells without damaging adjacent structures, and is thought to act via three mechanisms: distension of Schlemm's canal, reorganization of trabecular meshwork cells and stimulation of extracellular matrix production. Its efficacy has been demonstrated in several studies, with a 20-30% reduction in intraocular pressure in patients who have never undergone surgery. Few studies have investigated the efficacy of SLT in patients who have already undergone filtering surgery. The aim of this study is therefore to determine the efficacy of SLT in previously operated patients whose intraocular pressure remains insufficiently controlled.

The main aim of this study is to determine the trans-laminal cribrosa pressure difference (TLCPD) for normal tension glaucoma (NTG) patients from the brain and the eye in supine, upright and minor head down tilt positions. It is also to investigate the venous drainage system in the same body positions.

This study is a retrospective chart review to assess the tolerability and efficacy of treatment with Simbrinza™ used for patients with Open-Angle Glaucoma or Ocular Hypertension.

The investigators prospectively evaluate the new glaucoma premium edition (GMPE) software for spectral domain optical coherence tomography (SDOCT) and if this software is superior to the conventional one that is currently used for SDOCT.

The study will evaluate patients diagnosed with primary open angle glaucoma or ocular hypertension who are switched to Lumigan® UD monotherapy for medical reasons in accordance with physician standard clinical practice. All treatment decisions lie with the physician.

The purpose of this study is to observe the safety of the Glaukos® iStent® Trabecular Micro-Bypass Stent Model GTS100 in conjunction with cataract surgery in subjects with mild to moderate open-angle glaucoma.

Glaucoma is a leading cause of blindness worldwide, whose treatment - intraocular pressure lowering - is only partially effective in preventing disease progression. Accordingly, other variables, such as ocular blood flow-related factors, have been implicated in disease pathogenesis. However, most findings involving vascular variables come from partial, small-scale studies. Furthermore, recent technological advances have identified a number of ocular blood flow variables that have yet to be tested in large scale trials. Therefore, a study that specifically aims at uncovering the role of vascular aspects in glaucoma is needed. For this purpose, a cross-sectional, observational case-control study will be conducted in the University Hospitals Leuven. This will be the largest-yet study on the subject, involving more than 750 patients. This will allow the creation of a specific cohort of patients where the vascular aspects are thought to be particularly important (low-tension glaucoma). It will use the largest combination yet of vascular-related measuring techniques (dynamic contour tonometry, optic coherent tomography, colour Doppler imaging and retinal oximetry)

This is an observational study of patients diagnosed with Primary Open Angle Glaucoma (POAG) or Ocular Hypertension (OHT) who are insufficiently responsive to monotherapy and who are prescribed GANfort® (fixed combination of 0.3 mg bimatoprost and 5 mg timolol) by their physician.

This study compares efficacy (i.e. IOP and hypotensive medications) of phaco alone vs. combined phaco plus excimer laser trabeculotomy vs. combined phaco plus trabectome.
