Open-Angle Glaucoma

The primary study objective is to compare the effectiveness of the combination of phacoemulsification with intraocular lens implant with ELIOS or competitor device in reducing IOP at 12 months postoperatively.

This study evaluates the safety and preliminary efficacy of topical sterile human insulin eye drops (EYED-002) in patients with open-angle glaucoma. The study uses a phase 1/2 dose-escalation design followed by a masked, randomized, placebo-controlled phase. Insulin is formulated as preservative-free eye drops and delivered once daily. The primary objective is to determine the safety profile of topical insulin; secondary objectives assess effects on retinal structure, visual field, visual acuity, contrast sensitivity, and quality of life.

The purpose of this study is to evaluate the effect on 24-hour IOP reduction of netarsudil-latanoprost fixed combination in one eye compared to latanoprost alone in the contralateral eye, dosed daily, 1 drop at night (QD, PM) in adult subjects, at least 18 years of age, with open angle glaucoma (OAG) or ocular hypertension (OHT).

Glaucoma surgery currently relies on a wide therapeutic arsenal, ranging from conventional filtering surgeries to minimally invasive glaucoma surgery (MIGS). These techniques offer distinct efficacy and safety profiles, allowing tailored management across a broad spectrum of patients. Traditionally, surgical success has been evaluated using objective clinical outcomes, such as intraocular pressure (IOP) reduction and decreased reliance on topical treatments. However, the shift toward patient-centered medicine now requires consideration of the patient's perspective, including their subjective experience and the impact of treatment on quality of life. In this context, quality-of-life assessment has become a key component, promoting therapeutic alliance and patient adherence to care pathways. Despite its importance, few studies have evaluated and compared quality of life after glaucoma surgery using comparable surgical techniques. Furthermore, to our knowledge, no study has specifically assessed the independent effect of postoperative follow-up on quality of life after filtering surgery with a bleb. Given that postoperative management can be prolonged and demanding, it may significantly influence patients' perceptions of surgical outcomes and overall well-being. This study aims to address these gaps by providing a more comprehensive evaluation of the impact of glaucoma surgery beyond traditional clinical outcomes. It may represent a first step toward the development of a more appropriate assessment tool that incorporates the realities of postoperative follow-up and the specific experiences of patients undergoing filtering surgery. The study is based on the following hypotheses: filtering glaucoma surgery preserves patients' quality of life, with a stable NEI VFQ-25 score at six months postoperatively; postoperative quality of life may be influenced by the patient's postoperative care pathway; and quality-of-life scores remain correlated with objective clinical parameters, including intraocular pressure, visual acuity, medical treatment burden, and visual field damage.

The objective of this study is to evaluate whether reduction in topical medication with the injection of a sustained release capsule (Durysta) leads to a reduction in ocular surface inflammation, indicated by levels of caspase-1, an inflammatory biomarker.

The Investigators will investigate the efficacy of combining the standalone iStent infinite and iDose that are minimally invasive surgical and drug depot options are a safe and effective alternative to filtering surgery for intraocuar pressure reduction in patients with medically uncontrolled open angle glaucoma.

A randomized, multi-site, parallel-group, prospective study of patients who are adults with a diagnosis of mild to moderate open-angle glaucoma (OAG), currently on an on-label use of combination topical medication of Cosopt and Latanoprost for a minimum of 1 month.

Real-World efficacy of Hydrus Microstent with OMNI Surgical System in combination with Phacoemulsification: a retrospective analysis

This study aims to determine whether a combination of vitamins (B6, B9, B12, and choline) can help protect the eyes of people with glaucoma and slow vision loss. The study will assess whether these vitamins support retinal cells and maintain or improve their function. Adults aged 18 and older with primary open-angle glaucoma (including normal-tension glaucoma) or pseudoexfoliation glaucoma, and those with mild to moderate glaucoma, may be eligible. Participants must meet specific medical criteria and cannot take additional vitamin supplements during the study. Participants will be randomly assigned to one of two groups: one group will take a daily vitamin supplement (B6, B9, B12, and choline) for one year, along with standard glaucoma care, while the other will continue standard care without extra vitamins. The vitamins used are well tolerated at selected doses, with possible mild side effects such as an upset stomach or tingling sensations. They will visit the clinic five times over 12 months (at the start, and at 3, 6, 9, and 12 months) for routine eye tests, including measuring eye pressure, checking vision and visual fields, taking scans of the eye's nerve layers (OCT), and completing an electroretinogram (ERG) to assess retinal function. Blood samples will also be collected. If the vitamins are effective, this could provide an additional strategy alongside current eye pressure lowering treatments to reduce vision loss.

The purpose of this study is to perform trabeculopuncture a test to determine the distal outflow tract function to predict the success of ab interno trabeculectomy.

The aim of this clinical trial is to investigate whether oral semaglutide can be used to treat open-angle glaucoma. The main question it aims to answer is: Does oral semaglutide safely improve inner retinal function in patients with open-angle glaucoma as measured by the photopic negative response of the electroretinogram. Researchers will compare oral semaglutide to a placebo (a look-alike substance that contains no drug). Participants will: * Take semaglutide or a placebo every day for 6 months. * Visit the clinic 5 times in total for tests and interviews: At baseline (the first day they are included in the study), after 1 month, after 2 months, after 3 months, and after 6 months (the last day they are included in the study).

This is a post-market clinical follow-up, retrospective chart review of MIMS® surgical procedures conducted during time period between Sep 2023 and May 2025.

A long-term (24 and 30 months) follow-up extension, prospective, non-interventional, open label study for data collection from subjects who underwent prior MIMS® inferonasal surgery, in continuation of the previous clinical investigation with the MIMS® Device (MMS-EEU-5).

The goal of this clinical trial is to show non-inferiority of the MIMS® device/procedure with Mitomycin-C, in terms of its surgical success rate, compared to trabeculectomy with Mitomycin-C in subjects diagnosed with primary open angle glaucoma, whose intraocular pressure is not controlled despite polypharmacy. Eligible screened participants will undergo the MIMS® procedure and will be followed for a period of 12 months in this single-arm study. Investigators will compare the results of this study to the surgical success rate of traditional trabeculectomy with Mitomycin-C.

A randomized, double-blind, parallel-group, two-arm, multiple dose, multicenter, clinical endpoint bioequivalence study

This clinical trial, led by Dr. Enitan A. Sogbesan at the Hamilton Regional Eye Clinic, St. Joseph's Healthcare Hamilton, aims to compare the efficacy and safety of non-steroidal anti-inflammatory drug (NSAID) ketorolac alone versus a combination of ketorolac and the corticosteroid fluorometholone, and a control group receiving no postoperative treatment. The trial will evaluate these treatment strategies following Selective Laser Trabeculoplasty (SLT) in patients with open-angle glaucoma. The primary objective is to determine the most effective postoperative management strategy to reduce inflammation, improve patient comfort, and control intraocular pressure (IOP). Participants will be randomly assigned to one of the three groups, with follow-up visits scheduled at 1 hour, 1 week, 1 month, 3 months, 6 months, and 1 year post-SLT. The study's findings aim to guide clinicians in optimizing postoperative care for better patient outcomes.

This study aims to investigate the effect of different types of glaucoma surgery on aqueous dynamics parameters (IOP, aqueous flow rate, trabecular outflow facility and uveoscleral outflow) in patients with uncontrolled open angle glaucoma or ocular hypertension (OHT)
