Filter by:The purpose of the study is to investigate the IOP difference between normal and glaucomatous eyes using standard ophthalmic tonometry devices while subjects are performing different standard yoga asanas. The IOP of participants will be measured prior, immediately at start of the asana, 2 minutes into the asana, and immediately after assuming a sitting position. The patient will wait 10 minutes and a final IOP will be taken. Four standard yoga asanas will be tested.
The purpose of this prospective randomized study is to assess and compare the clinical efficacy and safety of primary trabeculectomy with Ologen® collagen implant and cohesive viscoelastic (Provisc®) - augmented trabeculectomy in patients with medically uncontrolled steroid induced glaucoma.
Purpose: To study the feasibility of a larger study by determining the tolerability of measuring blood pressure (BP) and intraocular pressure (IOP) over 24 hours in an ambulatory fashion with automatic devices. Participants: 20 patients with moderate to severe normal tension glaucoma and 20 non-glaucomatous patients. Procedures (methods): Both BP and IOP will be measured automatically in each participant in an ambulatory fashion during a 24-hour period. BP will be monitored using an appropriately sized cuff Oscar 2 (Suntech Medical, Morrisville, NC), which will be placed by a person trained in ambulatory BP monitoring devices. The device will be set up to automatically inflate every 30 minutes during the day and every hour during the night to measure and record the BP. IOP will be measured using Sensimed Triggerfish contact lens (Sensimed AG, Lausanne, Switzerland); the measurements will be taken and recorded every 10 minutes. The contact lens will be inserted by eye doctors (investigators). Both monitoring devices will be removed the following day.
Monocentric prospective study conducted in two phases evaluating the secretion and elimination of aqueous humor by fluorophotometry in patients with glaucoma treated with cyclo-coagulation with ultrasound. Population selected: - Patients with refractory open angle glaucoma despite previous treatments currently validated for glaucoma. The purpose of our study is: - To evaluate the mechanism of action of glaucoma treatment by cyclo-coagulation with high intensity focused ultrasound in studying the secretion and elimination of aqueous humor by fluorophotometry. Planning: - First phase: 2 patients (feasibility study) If reduction of at least 10% of the flow of aqueous humor production at one month in the first two patients in the feasibility study, further in second phase. - Second phase: 6 patients
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

This is a pilot, proof of concept study to evaluate the safety and efficacy of ALZ-1101 dosed once daily for 28 days compared to latanoprost 0.005% ophthalmic solution in patients with elevated intraocular pressure not adequately controlled with latanoprost.
The objective of this study is to demonstrate the clinical safety of latanoprostene bunod 0.024% once daily (QD) over a 1-year treatment period.
The aim of this study is to analyze similarities and evaluate interchangeability of Visante and Cirrus OCT (optical coherent tomography)and to compare agreement between gonioscopy and the two systems for evaluation of anterior segment parameters.
The study is designed to assess the safety of Hyaluronan Thiomer i.o. implant in patients with primary open angle glaucoma undergoing a combined phacoemulsification - non penetrating deep sclerectomy procedure. In this study, Hyaluronan Thiomer i.o. will be implanted during a combined surgery of cataract and non - penetrating deep sclerectomy in a group of 16 patients with primary open angle glaucoma and clinically significant cataract. Given that a considerable number of glaucoma patients also suffer from cataract, it is reasonable to test Hyaluronan Thiomer i.o. during a combined procedure of phacoemulsification and deep sclerectomy. This is also of importance because a combined procedure avoids the need of a second operation in this group of patients. Finally, it has been shown that combined phacoemulsification - deep sclerectomy does not induce a further risk compared to deep sclerectomy alone(open phase I study). Safety will be assessed based on the occurrence of adverse events. Efficacy assessments will be performed at every visit and efficacy analysis will include: - Proportion of subjects at each study time point which will need additional IOP lowering drug therapy to achieve an IOP reduction to values < 21 mmHg. If a subject needs more than one drug to achieve target IOP, the number of drugs needed to achieve adequate IOP reduction will be recorded. - Proportion of subjects at each time point which will need Neodymium:YAG goniopuncture to achieve an IOP reduction to values < 21 mmHg.
