Filter by:The goal of the study is to prospectively evaluate and compare Hydrus microstent to the iStent Inject Wide in combination with cataract surgery in patients with mild to moderate open angle glaucoma. Hydrus and iStent are the two FDA approved trabecular meshwork targeting microstents to treat open angle glaucoma in conjunction with cataract surgery.
It is a phase III, multi-center, randomized, single-blind (to evaluator), parallel, and positive-controlled clinical trial evaluating the efficacy and safety of OPC-1085EL in the treatment of primary open angle glaucoma or ocular hypertension in Chinese subjects. It is planned that 240 subjects (120 in each group) will be randomly assigned to receive OPC-1085EL or 0.005% latanoprost ophthalmic solution (latanoprost) at a ratio of 1:1.
Project Summary Abstract: While lifestyle changes, particularly exercise, have been suggested to protect against damage to ganglion cells in animal models, definitive evidence demonstrating its benefits in humans is lacking. Here, in a group of individuals with ganglion cell damage from glaucoma and a separate control group without significant eye disease, the investigators study the effects of a remotely delivered exercise training program by a trained exercise physiologist consisting of resistance training combined with cycling on a stationary bike. Three outcomes will be examined to evaluate if exercise might be of potential long-term benefit in protecting ganglion cells. In Aim 1, the investigators will examine the trial's primary outcome, a comparison of the pointwise change in the visual field (VF) sensitivity over the exercise period compared to a preceding usual activity period. Given the subjective nature of VF testing, Electroretinogram (ERG) testing will be employed as a more objective secondary outcome. Together, these outcomes will determine if neuro recovery is possible with exercise in individuals with GC damage from glaucoma (as has been demonstrated for Intraocular pressure (IOP)-lowering and, more recently, nicotinamide) and if neuro enhancement (improvement in the function above an already-normal level) is possible in adults without eye disease. In Aim 2, the investigators will examine if an exercise produces physiologic changes in the human eye (glaucoma and control), which would give mechanistic plausibility for a neuroprotective effect. Specifically, the investigators will compare exercise-induced changes in large vessel retinal blood flow, the density of and flux within perfused capillaries, large-vessel arterial-venous oxygen (O2) saturation gradients, inner retinal O2 metabolism, and serum levels of brain-derived neurotrophic factor (BDNF) to changes occurring in the preceding usual activity control period. Finally, in Aim 3, the investigators will examine if exercise benefits quality of life (QOL) in individuals with VF damage from glaucoma within specific domains (mobility, ocular discomfort, and mood) independent of changes in visual function. Together, these findings will provide important information regarding whether exercise produces short-term changes in eyes, which suggests possible long-term protection against ganglion cell damage.

This study sought to determine the percentage of normal eyes that followed the ISNT rule by retinal nerve fiber layer (RNFL) and neuroretinal rim thickness measurements using optical coherence tomography (OCT) , and secondarily, whether alternative rules may be more applicable or easily generalized.
A prospective, multicenter, randomized, single-masked, post-market clinical trial comparing cataract surgery in conjunction with ab-interno canaloplasty utilizing the iTrack Advance canaloplasty device (Nova Eye, Inc.) to cataract surgery only in patients with mild to moderate, primary open angle glaucoma. Subjects will be followed for 12 months.
Micro pulse transscleral laser treatment (MP-TLT) is a relatively new method to reduce the intraocular pressure (IOP) in glaucoma. New recommendations regarding the treatment protocol has recently been developed and was published 2022. The overall objective is to evaluate the efficacy and safety of the proposed treatment method in an independent study. In addition, the outcome of MP-TLT in patients with pseudoexfoliation glaucoma, which is relatively common in the Nordic countries, and primary open angle glaucoma will be studied separately. The IOP change over the course of one year will be monitored, as well as success rate and survival. Further, patient-reported discomfort from the treatment and the occurrence of any adverse events or complications will be studied.
The objective of this early feasibility clinical study is to evaluate the safety and effectiveness of the GORE Glaucoma Drainage Implant (2 configurations) in subjects with primary open-angle glaucoma that is uncontrolled by hypotensive medications or for which conventional incisional glaucoma surgery would be more likely to fail due to scarring.
The purpose of this study was to asses differences in nycthemeral (24-h) intraocular pressure (IOP) profiles and outflow facilities between patients who have undergone epibulbar microshunt implantation and ab interno trabeculectomy, respectively.
