Active clinical trials for "Glaucoma"

selective alpha-2 receptor agonists cause changes in intraocular pressure and pupillary size thus may affect patient quality of life.

The purpose of this study is to evaluate the safety, efficacy, and usability of an eyedrop bottle adaptor that creates smaller eyedrops, Nanodropper, in an open-angle glaucoma/ocular hypertension patient population.

Two primary care-based screening systems will be used to identify subjects with referrable glaucoma to hospital care. Subjects between 55 to 65 years old living in two primary care areas (urban area in Lisbon ; countryside setting in Minho) will be invited to a one-time assessment of optic disc and intraocular pressure (IOP). Criteria for referral will differ between centers, with one arm (Lisbon) using an artificial intelligence (AI) reading software of the optic disc picture, the other (Minho) will base their referral based on optical coherence tomography (OCT) retinal nerve fibre layer abnormality. A masked reading center will be established to set the ground truth for diagnosis. This pilot screening trial will explore the level of agreement between both systems as well as their cost effectiveness and identify diagnostic composite scores that could maximize the screening process. Secondary analyses will include the identification of population characteristics that increase effectivity of screening process as well as determining the population less likely to adhere to screening programmes.

The purpose of this study is to evaluate the safety and effectiveness of implanting a new version of an interposition supraciliary implant (SV22) as a stand-alone therapy for lowering intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG) and primary narrow angle glaucoma (PNAG) who have failed at least one class of topical medical therapy

Glaucoma is the second most common blindness disease in the world, second only to cataracts. The current treatment of glaucoma is mainly to reduce intraocular pressure.At present, two commonly used surgical methods are trabeculectomy and implantation of drainage valve. These methods are superior to drug treatment in reducing intraocular pressure, but the effect duration of these two methods is not long, and there may be serious complications and failure. Compared with traditional glaucoma surgery, MIGS may have better safety.The XEN45 gel implant is a collagen tube with a length of 6 mm and a diameter of 45 µm, which creates a new channel for drainage of aqueous humor by connecting the anterior chamber and the subconjunctival space. The implant is composed of porcine gelatin cross-linked with glutaraldehyde, and has good biocompatibility and tolerance. Therefore, after the advent of XEN45 products, more and more studies have shown that this treatment has excellent safety and effectiveness in reducing intraocular pressure in patients with open-angle glaucoma. Considering that the XEN45 gel stent has been in the market for a relatively short time, we conducted this prospective study to investigate the effect of XEN45 surgery in the treatment of primary open-angle glaucoma, in order to support ophthalmologists in formulating the best surgical plan for patients. The promotion of this surgical method.

This is a Phase I/II stage to investigate the safety, tolerability, and ocular hypotensive efficacy of TO-O-1001 in healthy volunteers and patients with Open-Angle Glaucoma or Ocular Hypertension. The proposed trial consists of 3 study parts to be conducted at Nucleus Network Melbourne. This study will enroll up to 34 evaluable healthy volunteers in part 1(SAD) and part 2(MD) and 16 evaluable patients with Open-Angle Glaucoma or Ocular Hypertension in part 3(MD). Note- As of 14Mar2023, enrolment has been completed for Part 1 and Part 2 and recruitment is pending now for Part 3.

To evaluate the safety and efficacy of the XEN® Gel Stent in mild to moderate glaucoma patients undergoing glaucoma surgery.

A multicenter, parallel, open, non-inferior randomized controlled trial was conducted to compare the effectiveness and safety of phacotrabeculectomy and phacogoniotomy in the treatment of advanced primary angle closure glaucoma, so as to provide a better surgical alternative.

A Phase III, Multinational, Multicenter, Investigator-Masked, Randomised, Active-Controlled Trial, comparing the efficacy and safety of DE-130A with Xalatan® in Patients with Open-Angle Glaucoma or Ocular Hypertension over a 3-Month period, followed by a 12-Month Follow-Up with Open-Label DE-130A Treatment

To determine the safety and efficacy of Kahook dual blade over Trabectome in lowering intraocular pressure in glaucoma patients. Glaucoma surgery will be performed in conjunction with cataract surgery. The investigators hypothesize that the Kahook dual blade is as effective as Trabectome in lowering intra-ocular pressure (IOP), and as safe with a similar rate of post-operative complications such as hyphema.
