Active clinical trials for "Glaucoma, Open-Angle"

The overall objective of this study is to determine the safety and usability of OMNI surgical system in performing canaloplasty and trabeculotomy. Outcome measures will include 1) adverse events (intraoperative and perioperative) 2) BCVA 3) Secondary surgical interventions 4) mean IOP and 5) mean number of hypotensive medications

To compare the effect of intraocular pressure control and the incidence of peripheral anterior synechia between CLASS combined with phacoemulsification and CLASS alone in the treatment of primary open-angle glaucoma

The purpose of the study is to provide evidence that the efficacy of Xalatan will be superior to Apo-latanoprost and Co-latanoprost in the reduction of intraocular pressure in patients with primary open angle glaucoma. The study will also aim to prove the tolerability of Xalatan in terms of ocular hyperemia will be equivalent to its generic counterparts.

This study examines efficacy and tolerability of 3 different Latanoprost 0.005% eyedrops preparations, commercially available in Italy, in subjects affected by primary open angle glaucoma.

The primary purpose is to compare the effect of immediate therapy to lower the intraocular pressure (IOP) versus late or no treatment on the progression of newly detected open-angle glaucoma, as measured by increasing visual field loss and/or optic disc changes. The secondary purposes are to determine the extent of IOP reduction attained by treatment, to explore factors that may influence glaucoma progression, and to describe the natural history of newly detected glaucoma.

To compare the long-term effect of treating newly diagnosed open-angle glaucoma with standard medical treatment versus filtration surgery.

To investigate the effect of patterned laser trabeculoplasty (PLT) compared to selective laser trabeculoplasty (SLT) on intraocular pressure (IOP) in treatment naiv patients suffering from open-angle glaucoma or ocular hypertension. Values for IOP will be measured at baseline, 1 day and 1 month post-interventional as well as 2, 3, 6, 9, 12, 18 and 24 months after treatment. Trial with medical device

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.

The aim of the study is to evaluate the safety and effectiveness of the IOPtiMate (OT-135P) in Laser Assisted Non-Penetrating Glaucoma surgery in Open-Angle and Pseudoexfoliative Glaucoma patients.

Laser endoscopic cyclophotocoagulation (ECP) has been in use for the treatment of glaucoma for over 20 years and is usually used in conjunction with cataract surgery. In the US it is one of the most commonly performed cataract 'plus' surgeries. The take-up of ECP laser has been much lower in the UK and Europe. This is partly due to the lack of robust clinical evidence from randomised controlled trials to justify its use in routine practice. More recently the advent of minimally invasive glaucoma surgery techniques (MIGS) has increased the options available for cataract 'plus' surgery. Without any randomised controlled trial data for the use of ECP laser in this context the increasingly popular use of MIGS devices, such as iStent (the current market leader) may further marginalise the use of ECP laser for cataract 'plus' surgery in patients with Primary Open Angle Glaucoma (POAG) and visually significant cataract. To further evaluate the use of ECP laser for the treatment of glaucoma in patients with glaucoma and cataract, investigators plan to conduct a randomised controlled trial comparing cataract surgery alone versus cataract surgery plus ECP laser surgery. Investigators will compare the efficacy of these interventions for the treatment of glaucoma based on clinical outcomes and also undertake a cost-benefit analysis, taking into account the cost of surgery, any reduction in clinical time allocation for procedures, the frequency of intra- and post-operative complications, and any reduction in the need for topical glaucoma treatments post-surgery, as well as the frequency with which further glaucoma filtering surgery is needed for patients in each group. Investigators anticipate that a total number of 160 patients (80 in each arm) will be adequate to detect whether there is any difference in efficacy between cataract surgery + ECP versus cataract surgery alone. Recruitment is expected to take around 9-12 months. Participants will undergo treatment wash-out (28 days minimum) of any eye drops they use for their glaucoma prior to data collection at baseline (before surgery) and prior to data collection at one-year and at two-years post-surgery. Results will be reviewed during an interim analysis at 6 months once 50 patients have reached that time point.
