The purpose of this study is to evaluate the clinical efficacy of the BREMEN eye drops in the treatment of primary open-angle glaucoma or intraocular hypertension.
To evaluate the effect on trabecular outflow facility of Netarsudil ophthalmic solution 0.02% compared to placebo
Treatment of elevated pressure in the eye (Intraocular pressure, or 'IOP') with eye drop medications has been shown to be effective in delaying or preventing the progression of glaucoma, and it is the only proven method for reducing the risk of glaucomatous visual field loss. This study is being conducted to determine how well DE-126 ophthalmic solution works (efficacy) in safely lowering IOP when dosed as topical eyedrops. This study will evaluate the safety and efficacy of four (4) concentrations of DE-126, when compared with latanoprost (0.005%) eye drops in patients with primary open-angle glaucoma or ocular hypertension. The IOP will be measured at 3 different times throughout the day, over 6 total visits during a 3-month treatment period (with up to 4 extra weeks observation if the patient must stop taking current eye drops to lower IOP). Safety assessments will be done throughout the study, including ocular signs and symptoms, vital signs, and clinical laboratory tests. While the most important time-point to measure IOP in this study and evaluate efficacy will be at the final study visit (month 3), IOP values will also be evaluated at other visits throughout the 3-month treatment period.
This study aims to test a new medical device, called the eyeWatch, used in filtering surgery for the treatment of glaucoma. This medical device has the following property: it allows better control of intraocular pressure in the initial postoperative phase by adjusting aqueous flow going through the device. The target criteria for the study are defined as: keeping intraocular pressure in target range; reducing the number of anti-glaucoma drugs; evaluating the number and type of postoperative complications. So far, this device has been already tested on 20 patients in Switzerland.
Studies have shown that ocular surface disease (OSD) is common among patients with glaucoma with a prevalence of 50% or more. The percentage of affected patients appears to increase with increasing number of topical anti-glaucoma products instilled. Both pre-clinical and clinical work has indicated that the preservatives used in anti-glaucoma drops, particularly benzalkonium chloride, are mainly responsible for this detrimental effect. As such more and more anti-glaucoma drugs without preservatives entered the market. To prove that switching from preserved to unpreserved antiglaucoma medication improves the signs and symptom of OSD is, however, not easy. This is on the one hand related to the physiological variability of these parameters over time and on the other hand to the poor association between signs and symptoms. Recently, a new method for measuring tear film thickness (TFT) using ultra-high resolution optical coherence tomography (OCT) has been introduced. Using this method, it has been shown that there is a correlation between reduced TFT and OSD symptoms. In the present study, it is hypothesized that changing patients who are on preserved prostaglandin formulations to preservative free tafluprost may be associated with an increase in TFT.
The Ex-PRESS Glaucoma Filtration Device is a small, non-valved implant that was designed to lower intraocular pressure (IOP) by shunting aqueous humor from the anterior chamber into the subconjunctival space. The implant was developed in response to the need for more straightforward, standardized and safe surgical technique than standard filtration surgery. No iridectomy and no sclerectomy is needed if an Ex-PRESS device is implanted under a partial-thickness scleral flap. This may reduce surgical time and complications when compared to a standard trabeculectomy. In some studies it has been found to be safe and effective with few complications, even in high-risk patients. No previous studies have compared filtration surgery with Ex-Press implant to deep sclerectomy.
The study will evaluate the efficacy and safety of the implant and intra-ocular pressure (IOP) lowering effects with or without glaucoma medications. The procedure will be a stand-alone surgery. Overall, the patient will be asked to perform several examinations up to 24 months after surgery. The primary efficacy objective of the present study is to show the IOP reduction under medication 6 months after surgery compared to medicated diurnal IOP at screening.
This pilot study will test the preliminary efficacy and feasibility of an intervention protocol for one method of electric current stimulation, repetitive transorbital alternating current stimulation (rtACS), to treat visual impairment in people with glaucoma. We will evaluate a study protocol to use in future clinical trials to test the effectiveness of rtACS to ameliorate the progressive effects of vision loss both structurally and functionally in the eye, the visual pathway, and in regard to people's independence (i.e., functional ability). In this prospective, randomized controlled, double-masked pilot study, we will: 1) determine an effect of rtACS on ophthalmic structure and function (from retina to visual brain), 2) assess the methodology of procedures for assessment of people's functional ability and quality of life (QoL) to determine an effect of rtACS, and 3) assess the feasibility and implementation of the pilot study protocol for a larger multi-site, randomized controlled trial.
The goal of this study is to evaluate the efficacy and safety of the novel form of trans-scleral cyclophotocoagulation using micropulse diode laser and trans-pars plana treatment (Micropulse TSCPC, mTSCPC MP3, IRIDEX CYCLO G6™ Glaucoma Laser System, CA, USA) in adults for the treatment of uncontrolled glaucoma.
