NCT05730478
Study aiming to compare between anterior segment Optical Coherence Tomography and Ultrasound BioMicroscopy In Glaucoma aSSESMENT
NCT05685485
The aim of this study is to assess whether delaying early flow through the Ahmed tube shunt may improve the post-operative surgical outcomes and provide a more predictable outcome. To assess this the investigator will conduct a, randomized prospective, multi-centered study with collaborators at WashU in St. Louis, Duke University, Indiana University and the University of Pittsburgh. Participants will be randomized to have an AGV placement with tube ligation (no-early flow) and without ligation (allowing for early flow). IOP will be measured at day one, week one, and months, one, three six, and twelve. Additionally, clinical data regarding number of glaucoma medications, and complications post-operative complications will also be collected.
NCT04037917
Study Name: The CorNeat EverPatch - a First-In-Man Clinical Study for demonstrating the Safety of a Synthetic Tissue Substitute for concealment of artificial implants and glaucoma tube shunts Objective: The objective of this clinical trial is to demonstrate the Safety of the Corneat Everpatch for concealment of artificial implants and glaucoma tube shunts The study will consist 10 subjects requiring concealment of a glaucoma shunt or other ophthalmic implant. Eligible subjects who signs an ICF will be enrolled to the study. Subjects will be implanted with the Corneart EverPatch as part of a glaucoma shunt surgery or during a corrective surgery to repair a breached conjunctiva over an implanted device. Subjects will be monitored for a period of 12 months post-op during which follow up visits will occur at 1 week, 1, 2, 3, 6, 9 \& 12 months following surgery including clinical examination of the operated eye using slit-lamp biomicroscopy and imaging using OCT or UBM (will be performed only at the 6 \& 12 months follow up visits).
NCT03996200
Study to assess safety and performance of MINIject SO627 in patients with open angle glaucoma.
NCT04676126
The purpose of this study is to prospectively analyze changes in macular pigment optical density and dermal carotenoid levels as they relate to visual field function in patients prescribed a macular pigment-containing medical food (Lumega-Z), in combination with a topical carbonic anhydrase inhibitor.
NCT03624361
The study will evaluate the efficacy and safety of the MINIject glaucoma implant and Intraocular Pressure (IOP) lowering effects with or without glaucoma medications. The procedure will be a stand-alone surgery. Overall, the patient will be asked to perform several examinations up to 24 months after surgery.
NCT03187418
The goal of this study is to evaluate the efficacy and safety of the novel form of trans-scleral cyclophotocoagulation using micropulse diode laser and trans-pars plana treatment (Micropulse TSCPC, mTSCPC MP3, IRIDEX CYCLO G6™ Glaucoma Laser System, CA, USA) in adults for the treatment of uncontrolled glaucoma.
NCT04052165
Glaucoma is a group of diseases that damage the eye's optic nerve, result in progressive visual field defect and blindness. The aim of glaucoma management is to reduce IOP, and glaucoma implant surgery is the alternative treatment that can be chosen. The effectiveness of the implant on the end stage glaucoma patients was evaluated by the reduction of intra ocular pressure (IOP) and well formed blebs that were evaluated clinically and by using anterior scanning optical coherence tomography (AS-OCT). The safety of the implant was determined by the regression of the clinical symptoms and there were no severe complications such as implant extrusion. Two patients developed improvement of the visual acuity. This was an unpredictable positive result.
NCT03797846
The aim of the study is to compare the effectiveness and safety of two types of intraoperative eye fixation: for the superior rectus muscle and traction suture in the peripheral cornea. This is a prospective randomized trial with a 6 month follow-up period, which covers patients with open angle glaucoma qualified for combined glaucoma procedure (phacotrabeculectomy). In I group, the intraoperatively fixation in the peripheral part of the cornea is used, in II group the bridle suture for the superior rectus muscle is performed.
NCT03682783
This study will develop an artificial intelligence (AI) program for the screening of glaucoma.
NCT03138928
Purpose: To report the follow-up data for patients who had XEN45 gel stent implantation, a new method of minimally invasive glaucoma surgery (MIGS). Material and Methods: Fifteen eyes of fifteen patients who had XEN45 gel stent implantation surgery were investigated in the study. All the patients were examined preoperatively and at the following postoperative time points: 1 day; 1 and 2 weeks; and 1, 2, 3, 6, and 12 months. Intraocular pressure (IOP) was measured by Goldmann applanation tonometry. Combined surgical procedures (XEN 45 + phacoemulsification + intraocular lens) were performed in the cases that had cataracts in addition to glaucoma.
