Active clinical trials for "Glaucoma, Open-Angle"

Pigment dispersion syndrome is a rare condition where anomalous iris configuration leads to posterior iris bowing with subsequent friction with the lenticulozonular unit resulting in dispersion of pigment from the back surface of the iris into the anterior segment as well as thinning with resultant transillumination defects in the mid iris segment. The released pigment is deposited in various parts of the anterior segment resulting in a constellation of clinical signs: Krukenberg Spindle: Back surface of the cornea Zentmayer ring: Back surface of the lens. Egger line: Anterior vitreous face. More importantly, pigment accumulated in the trabecular meshwork leading to visible hyperpigmentation of the trabeculum seen by gonioscopy. This leads to reduction of aqueous outflow which leads to ocular hypertension or even glaucoma which is known as pigment dispersion glaucoma which is considered one of refractory glaucomas. Current practice in the management of pigment dispersion syndrome revolves around the management of glaucoma when it develops by IOP lowering medication, Laser trabeculoplasty or peripheral iridoplastyor glaucoma surgery as a last resort. The only prophylactic measure in practice that is aimed at preventing the progression from mere pigment dispersion to pigment dispersion glaucoma is the long term use of miotic eyedrops e.g. Pilocarpine which comes with both risks and side effects i.e. the risk of retinal breaks and detachment which is even higher in a cohort which is predominantly myope, the constriction of visual field and ocular surface complications. In this interventional case series, the investigators assess the efficacy of a novel Argon Laser iridoplasty in the management of pigment dispersion through correcting the posterior iris bowing and hence halting the dispersion process so that glaucoma wouldn't develop in the first place instead of managing glaucoma after it sets in which proved refractory.

The purpose of this post-approval study is to evaluate the rate of Hydrus Microstent malposition and associated clinical sequelae occurring within 24 months post-operation. Qualified subjects will undergo uncomplicated cataract surgery with placement of a monofocal intraocular lens (IOL), followed by implantation of the Hydrus Microstent.

Phase IV randomized, double blind, multicenter, parallel group clinical study to evaluate the efficacy of the combined use of Krytantek Ofteno PF® and Gaap Ofteno PF®, both applied every 12 hours, versus the use of Eliptic Ofteno PF® Plus Gaap Ofteno PF®, both applied every 12 hours, in patients with open angle glaucoma or ocular hypertension during 90 days

The purpose of this study is to determine whether Metformin could prevent the progression of glaucoma in a safe and effective manner.

To assess efficacy, and safety of a single sustained release dose of the OTX-TIC drug product (2 travoprost dose strengths) in subjects with Open Angle Glaucoma (OAG) or Ocular Hypertension (OHT)

A prospective, multicentre, randomized, blinded, masked study that involves the enrollment of 60 patients affected by open angle glaucoma (OAG). Patients selected according to the inclusion / exclusion criteria, after signing the informed consent, will be randomized into two groups: In a group of patients with OAG, Citicoline in oral solution (10 ml / day, Neurotidine®) will be administered for 12 months (Citicoline Treated Group, TC Group) in another group of patients with OAG will be administered Placebo (Containing all excipients of Neurotidine ®) (10 ml / day) for 12 months (Placebo Treated Group, TP Group) Randomization will be done by dividing the selected patients into two groups based on similar characteristics of: age, perimetric defect and, mainly, retinal-cortical time (RCT) values. Patients will be assigned to each group by an investigator not involved in functional and structural testing. The key will be opened only at the end of the treatment in order to evaluate the first effects. The Primary Objective was to evaluate whether treatment with Citicoline in oral solution can produce an improvement of the post-retinal neural conduction, that is delayed in patients with OAG. The Secondary objective was to evaluate in patients with OAG whether the possible changes in post-retinal neural conduction induced by treatment with Citicoline in oral solution (information obtained through electrophysiological recordings) are associated or not with morphological and functional variations of the nervous structures forming the visual pathways (nucleus geniculatus lateral, optic tract, visual cortex, information obtained through the acquisition of structural and functional magnetic resonance imaging) and whether both conditions can be related to the morpho-functional variations of the retinal ganglion cells and of the visual field (VF).

This clinical study has two phases: Phase 1 and Phase 2a. Phase 1 is an open-label, single ascending dose (SAD), while Phase 2a is a randomized, single-masked (participant) with a sham control.

A multicenter, randomized, clinical trial to evaluate the efficacy of canaloplasty performed as a standalone procedure using the iTrack™ Advance canaloplasty device (Nova Eye, Inc.) as compared to the OMNI® Surgical System (Sight Sciences) in patients with mild to moderate primary open-angle glaucoma.

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.

The purpose of this study is to evaluate the effect of methazolamide, 25 mg or 50 mg tablets once a day for a week than twice a day for a week, on lowering intraocular pressure and the safety of methazolamide.
