Active clinical trials for "Ocular Hypertension"

We hypothesize that glaucoma patients demonstrate an impaired retinal vascular response to the flicker stimulus, and that this disturbance is predictive of the progression of glaucomatous damage. The response of a major temporal superior and inferior retinal artery and vein to a 60 seconds 12.5 Hz flicker light stimulation in 50 glaucoma patients, 50 ocular hypertensives and 50 controls (using the Retinal Vessel Analyzer) and to investigate how intraocular pressure relates to neurovascular coupling. In addition, 50 glaucoma patients and 50 ocular hypertension patients will be followed for 3 years for functional (visual field, automated perimetry with Octopus device) and morphological (retinal nerve fiber layer thickness, Optical Coherence Tomography Stratus ocular coherence tomography (OCT) device) glaucomatous damage progression, in order to test the predictive power of the retinal vascular flicker response for glaucoma progression.

This descriptive, non-interventional study will collect information on the presence of risk factors in newly diagnosed ocular hypertension and open-angle glaucoma patients in Canada.

Clinical, cross-sectional and prospective study to assess the images of the posterior pole of the retina of patients from the Glaucoma Unit of the IOBA and the Hospital Clínico Universitario de Valladolid during the period between May and December 2021. The aim of the project is to provide a sufficient number of images from posterior pole retinographies in patients with suspected glaucoma or with diagnosis of glaucoma in order to determine the sensitivity and specificity of an automatic glaucoma screening algorithm developed by the company Transmural Biotech S.L.

A 6-month, parallel, non-interventional trial investigating the level of adherence and the impact of dosing in open-angle glaucoma patients who receive either unfixed therapy with latanoprost once in the evening and timolol twice daily, or latanoprost/timolol fixed combination therapy once in the evening. All patients participating in this observational study will be monitored for their adherence with the use of Medication Event Monitoring System (MEMS). At the end of treatment periods treatment satisfaction will be assessed with selected questions from the Treatment Satisfaction Survey-Intraocular Pressure survey. This study will monitor objectively, for the first time, adherence and intraocular pressure control with fixed versus unfixed therapy. Finally it will help us to elucidate the impact of dosing (once-a-day versus three-times-daily) on the level of adherence in glaucoma.

Investigation of the occurrence of possible corneal swelling after continuous Intraocular pressure (IOP) monitoring with a contact lens-based Sensor during the sleeping period.

The purpose of this study is to evaluate adherence to DuoTrav® when reinforced by the use of the Travalert™ Dosing Aid.

To compare patients having PDS without and with OH or GL by documenting and following the clinical features and course of their disease and evaluating the patient's performance on a variety of diagnostic tests.

The hypothesis is that there is no difference in persistency between Xalacom and the alternative fixed dose combination products (Duotrav and Ganfort) over a 12 month period.

The purpose of this study is to evaluate performances of each parameters of spectral domain (Cirrus) optical coherence tomography for distinguishing between normal eyes, glaucoma suspect and glaucomatous eyes

The objective of the study was to evaluate whether timolol hemihydrate is more comfortable upon instillation than timolol maleate in sorbate. This was an observational study. Subjects with open-angle glaucoma or ocular hypertension were asked to complete a survey regarding their normal treatment. No treatment was prescribed.
