Filter by:In this Pilot explorative study, the investigators are going to estimate and compare the outcomes of three different delivery methods of MMC for Trabeculectomy: a subconjunctival injection of MMC 0.002% at the site of future Trabeculectomy two to four weeks before the surgery, a subconjunctival injection of MMC 0.01% intraoperatively and topical sponge applied MMC 0.02% intraoperatively (typical use) in patients with Primary Open Angle Glaucoma who did not have any filtering surgeries before. After obtaining informed consent from the patients, the patients are randomly divided into three groups via a block randomization method: Group A receives 0.1 mL MMC 0.002 % (0.1mL MMC 0.02mg/mL) subconjunctival injection preoperatively in superior conjunctiva at the site of future Trabeculectomy surgery. Group B receives 0.1mL MMC 0.01% subconjunctival injection intraoperatively at the site of Trabeculectomy and Group C receives conventional sponge delivery of MMC 0.02% intraoperatively. To avoid observer bias during postoperative evaluation of results, IOP staff obtaining measurements of IOP will be masked to the randomization allocation. All groups undergo conventional Trabeculectomy surgery (fornix-based) as scheduled, and the same routine follow up and post-op regimen will be scheduled for all three groups. Patients are routinely visited in the clinic at first day postoperatively, one week (+/-2 days), one month (+/-1 week), three months (+/-2 weeks), six months (+/-3 weeks) and finally at one year (+/-(4 weeks)). In each of these visits we will be assessing: Visual acuity, intraocular pressure, number and type of glaucoma medication, slit lamp examination of the anterior segment and fundus examination.
To prospectively investigate the effect and safety of implantation of the AADI glaucoma tube in eyes with medically intractable glaucoma in the period 2019 to 2020, at the Department of Ophthalmology, Odense University Hospital. The device will be implanted in eyes instead of the Bearveldt drainage device. Patients and data are prospectively registered to evaluate the effect and safety of the AADI device.
The purpose of this study is to evaluate the safety and effectiveness of a novel interposition supraciliary implant as a stand-alone therapy for lowering intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG) who have failed at least one class of topical medical therapy
This is prospective, non-randomized, single-arm study to assess the safety and effectiveness of lowering intraocular pressure with the Beacon Aqueous Microshunt. A total of 65 subjects will be enrolled at five centers. The primary endpoint will be assessed at 12 month follow-up.
This is a randomized, parallel arm, multicenter, double-blind trial. Patients with POAG will be randomized 1:1 ratio to receive: - Prostaglandin analogue (PGA) monotherapy + CoQun® (Arm A) - Prostaglandin analogue (PGA) monotherapy + Vehicle (Arm B)
The purpose of this study is to evaluate the intraocular pressure (IOP) lowering effect of iStent inject in eyes of subjects with primary open-angle glaucoma previously on two anti-glaucoma medications.
The purpose of this study is to demonstrate that the rate of clinically relevant complications associated with CyPass Micro-Stent placement and stability using the CyPass 241-S applier, as determined at 36 months in the postmarket setting, is less than the pre-specified performance target, which is based on experience with the CyPass Model E applier in COMPASS trial TMI-09-01 (NCT01085357).
Prospective Evaluation of Open-Angle Glaucoma Subjects treated with two second generation iStents and one iStent Supra
This study will evaluate the effectiveness of real-time data collected on patients taking topical medication to treat glaucoma. Patients will be randomized to two groups, the first of which will only use the study device to take their medication, while the second will use the study device and receive on-demand reminder messages, when necessary.
The main objective of this research is to study the cognitive and cerebral mechanisms of the integration of central and peripheral visual information during normal and pathological aging (ophthalmological patients with AMD and glaucoma) through fMRI studies. To assess the effect of normal aging, research will be conducted on a group of young participants with normal vision and a group of elderly participants with normal vision. Each participant will be assessed once during an MRI (during which the brain activity and behavioral performance will be measured). In order to evaluate the effect of pathological aging, research will be conducted on AMD patients, glaucomatous patients, and age-matched controls (normal vision), evaluated only once during an MRI examination.
