NCT07390890
This is a prospective, single arm, open label study conducted at a single site to evaluate the efficacy of Direct Selective Laser Trabeculoplasty (DSLT) in reducing medication burden in patients with medically controlled ocular hypertension or primary open angle glaucoma. The study will assess the primary endpoint of reduction in medication count at 6 months compared to baseline. Secondary endpoints include IOP reduction compared to baseline (both percentage and absolute), complete success rate (no increase in IOP without medications), proportion of eyes needing medication at 6 months, and any secondary surgical interventions at 6 months post-DSLT. Participants will undergo DSLT with 120 shots, 400 µm spot size, and 1.8mJ fixed energy delivered at the limbus over 2.4 seconds. Follow-up visits will occur at 1 month, 3 months, and 6 months post-procedure, with IOP measured using a calibrated Goldmann tonometer.
NCT07235592
The purpose of this study is to collect safety and performance data on the PRESERFLO™ MicroShunt XI in patients diagnosed with primary open angle glaucoma who are inadequately controlled on maximum tolerated medical therapy with intraocular pressure ≥18 mmHg and ≤35 mmHg and/or where glaucoma progression warrants surgery.
NCT04784234
This study is looking at changes in vision and visual function before and after a six month trial of a daily medical food called GlaucoCetin, formulated with ingredients to support and protect the optic nerve cells. Open angle glaucoma patients will be randomized to receive either a placebo or the medical food for 6 months. We hope to learn if this medical food can improve the vision of our glaucoma patients and to report the findings obtained to the general public.

NCT01742819
Glaucoma is one of the leading causes of blindness in the world. The key to prevention of visual loss from glaucoma is early detection of the disease or its progression and timely treatment. The proposed study will investigate the role of various tests in improving detection of disease progression in advanced glaucoma. Evaluation of the peripheral field of vision (visual field examination) remains the current standard for detection of progression in glaucoma. However, there is a lot of variability or inconsistency in eyes with advanced glaucoma, which could make it difficult to detect worsening of glaucoma with visual fields. The optic nerve demonstrates significant damage in such eyes and hence oftentimes repeat imaging of the optic nerve head is not helpful for detection of change. Therefore, imaging of the central retina (the innermost sensitive tissue lining the inside of the eye), called macula, has been proposed to supplant imaging of the nerve in eyes with severe glaucoma. The macula aids in detailed central vision. Since the macular retinal neural cells are the last ones to be affected in glaucoma, measurement of macular retinal thickness could provide significant information with regard to the course of glaucoma. In the proposed study, glaucoma patients will be tested and followed with various measurements done with newer versions of optical coherence tomography (OCT) imaging and visual field machines. The patients will undergo repeat imaging and visual field testing every 6 months over the course of 5 years. Rates of change will be estimated. We will explore if changes in various outcome measures derived from imaging are correlated with the corresponding visual field changes in glaucoma, and whether the former can be used as an alternative method for detecting simultaneous or subsequent glaucoma progression. The hypothesis for this proposed research is that macular OCT parameters are valid structural measures that can be used especially in advanced disease to follow the course of glaucoma.
NCT05564091
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 24 months.
NCT05198297
The purpose of this study is to assess the safety and effectiveness of the Hydrus Microstent for lowering intraocular pressure (IOP) in pseudophakic patients with open-angle glaucoma for whom IOP is not sufficiently controlled on topical hypotensive medication and prior to incisional glaucoma surgery.
NCT05557721
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.

NCT01864317
Glaucoma is among the leading causes for blindness in the western world. Elevated intraocular pressure (IOP) has been identified as the most important risk factor. However, some patients progress despite adequate IOP lowering while some subjects with elevated IOP never develop glaucoma. Other patients develop glaucoma although IOP measurements were always in the normal range. Therefore, other factors must be involved. In the last years, studies using MRI have been performed and evidence has accumulated that also changes in retrobulbar structures are present, in particular in the lateral geniculate nucleus and the visual cortex. However, these studies were limited by the low spatial resolution of the MRI instruments used. The investigators propose to overcome this problem by using an ultrahigh-field Magnetom 7T whole-body MR scanner (Siemens Medical, Germany) installed at the MR Centre of Excellence at the Medical University of Vienna. This scanner is equipped with a 32-channel head coil and the SC72 high-performance gradient system and is thus perfectly suited for structural and functional imaging. The aim of the present study is to investigate whether structural and functional parameters are altered in patients with primary open angle glaucoma (POAG), normal tension glaucoma (NTG), ocular hypertension (OHT) compared to healthy control subjects. The exact topographical survey of intracranial structures such as the LGN and the assessment of neuronal structures by DTI may allow for the better assessment of therapeutic responses to new neuroprotective agents.

NCT02989207
The aim is to perform a randomised feasibility trial preceding a large prospective randomised controlled trial (RCT) comparing three surgical methods - trabeculectomy with Mitomycin C (MMC), primary Baerveldt tube with MMC and Baerveldt tube without MMC - in black African/African Caribbean patients with Primary Open Angle Glaucoma (POAG) living in London. The UK Office of National Statistics estimated that among the population of England in 2007, approximately 4.3% were of African/African-Caribbean background, while in large cities such as London and Birmingham about 20% of the population is of African/African-Caribbean origin. For eye units in these cities, managing glaucoma in this population is challenging and we need to identify a better alternative to our current standard surgical treatment. There is now evidence from one RCT which shows better overall outcomes from tube surgery in comparison to trabeculectomy for glaucoma. However, this study did not address black populations specifically and did not address the potential role of MMC in tube surgery. This feasibility study will enable us to design a fully powered RCT with the aim of determining how best to optimise the surgical treatment of POAG in black populations, by comparing outcomes in three types of glaucoma surgery.
