Filter by:To the best of Investigator knowledge, no studies to this date have compared the safety and efficacy of ologen® Collagen Matrix in Primary congenital glaucoma (PCG) patients undergoing trabeculectomy. Given that filtration surgery is usually less successful in patients with developmental glaucoma; the purpose of this study is to compare combined trabeculectomy with trabeculotomy (CTT) with adjuvant ologen® Collagen Matrix versus CTT without ologen® in children with PCG. Investigator hypothesis is that CTT with ologen® Collagen Matrix would be as effective as CTT in IOP control, but with reduced scarring and long term healthier bleb morphology.
A target for glaucoma treatment is the intra-ocular pressure (IOP) which is lowered with medications, laser, or surgical intervention. The efficacy of different medication classes is well understood as their IOP lowering effects have been well documented. However, beyond the basic biochemical and pharmacokinetic actions, long-term effects of these drugs on IOP have not been adequately studied. Specifically, does long-term use of anti-glaucoma medications have lasting effects on IOP even with subsequent discontinuation of the medication? In Ontario, prostaglandin analogues are the most frequently prescribed first line anti-glaucoma medication. In our study, we examine the lingering IOP-reducing effects of the prostaglandin analogue anti-glaucoma drug class. Our overall objective is to determine if patients previously treated with prostaglandin analogues remain within acceptable treatment ranges 6 weeks after medication discontinuation, and if this IOP differs from pre-treatment baseline values. Half of participants will discontinue their prostaglandin analogue (PGA) treatment for 6 weeks, while the other half will continue their PGA therapy as prescribed by their ophthalmologist. Both groups will be followed closely throughout the 6 weeks to monitor changes in IOP. This can help us understand the lasting effects of medication use and can help better guide clinical care in optimizing glaucoma management, and help direct study designs of future research that involve any therapy secondary to prostaglandin analogue treatment.
Glaucoma is the second leading cause of visual impairment worldwide. Eye drop medications reduce vision loss from glaucoma by at least 60%, but eye drops must be taken every day to be effective. However, adherence to eye drop treatment is poor with only 50% of patients regularly taking their prescribed eye drops. The investigators are developing the Devers Drop Device (D3) eye drop monitor to accurately measure eye drop cap removal and to improve eye drop-taking behavior. The investigators will test eye drop adherence with the D3 device in a randomized, prospective clinical trial.
1. Study objective: To assess the efficacy and safety of collagen matrix implant (Ologen®; OLO) in phacotrabeculectomy and to compare with mitomycin C (MMC) augmented phacotrabeculectomy. 2. Study Design: The study is designed as a prospective randomized trial. Patient who meet the inclusion/exclusion criteria and sign the informed consent form will be included for this study. 3. Follow-Up: This investigation is including 7 post-operative visits and follow-up within 12 months from the date of surgery. Patients should be seen at postoperative days 1, 7, 30, 90, 180, 270 and 360.
This study is a prospective comparative study to gather pilot agreement and precision data in normal subjects, subjects with glaucoma, and subjects with retinal disease.
There are several publications that have demonstrated the protective role of cataract surgery against the development of long-term glaucoma, especially in cases of pseudoexfoliation glaucoma (PXFG). Cataract surgery in patients with pseudoexfoliation (PXF) is a procedure with higher rates of complications due to its smaller pupillary diameter and its greater zonular weakness, so lens extraction performed earlier could possibly reduce intra and postoperative complications. Given the severity and high prevalence of PXFG in our environment, investigators proposed a randomized clinical trial to evaluate the efficacy of cataract surgery in reducing the intraocular pressure (IOP) at 12 months and thereby change the course of the disease. The control group will have glaucoma treatment according to standard practice.
This is a multi center, open-label, single dose, safety study. Approximately 9 to 15 participants with open-angle glaucoma are assigned into 3 sequential dose-levels and will receive ANX007 administered as single, IVT injections.
This study aims to evaluate the effect of a single session of micropulse laser trabeculoplasty (MLT) on cornea in eyes with primary open glaucoma (POAG) and pseudoexfoliation glaucoma (PEXG).
- To evaluate prospectively the surgical outcome in terms of intraocular pressure control, potential advantages, disadvantages, success rate, complications and bleb morphology of this modified trabeculectomy with an extended subscleral tunnel (ESST) in comparison to the conventional subscleral trabeculectomy (SST) in management of uncontrolled primary open angle glaucoma. - This study will recruit 40 eyes of (40) candidate patients with primary open angle glaucoma (POAG) who are indicated for surgery. - The candidate patients will be recruited into 2 equal comparative groups. In group (A) 20 eyes (20 patients) who will undergo conventional (SST) with intraoperative mitomycin C (MMC) (0.03%) and group (B); 20 eyes of 20 patients will undergo trabeculectomy with an ESST also with intraoperative adjunctive MMC (0.03%).
Eligible patients underwent evaluation of ocular surface parameters by Ocular Surface Disease Index (OSDI) and Glaucoma Symptom Scale (GSS) questionnaires, Break Up Time test (BUT), Schirmer I test, corneal and conjunctival staining (Oxford scale) and conjunctival in vivo confocal microscopy (Heidelberg Retina Tomograph 3, Heidelberg Engineering Gmbh, Heidelberg, Germany). After the baseline visit, patients were randomized to use a PF ophthalmic solution containing HA 0.4% and TAU 0.5%, QID, in both eyes (Group 1) or to use a PF ophthalmic solution containing HA 0.2%, QID, (Group 2) in addition to the ongoing preserved hypotensive treatment. Follow-up visits were scheduled at 30 and 90 days.
