Active clinical trials for "Glaucoma"

The current study aimed to compare between the long-term surgical outcomes of 3 surgical options (viscotrabeculotomy (VT), visco-circumferential-suture-trabeculotomy (VCST) or combined VT-Trabeculectomy with MMC (VT-Trab) in treatment of infants with (Primary Congenital Glaucoma (PCG)) below 1 month of age.

The aim of this clinical study is to provide information about the variability of the intraocular pressure (IOP) self-measurements with the iCare HOME2 tonometer in comparison to the variability of the IOP measurements with the reference tonometer (iCare IC200), over a wide range of IOP values.

Patients with advanced glaucoma that are candidates for trabeculectomy will be included. Thorough ophthalmic examination including best corrected visual acuity, slit lamp examination, intraocular pressure (IOP) measurement, gonioscopy, funduscopy and specularly microscopy will be performed for all participants. Patients will be assigned randomly to 2 groups. In one group they will undergo fornix based trabeculectomy with conventional MMC 0.02% soaked sponges application. In the other group 0.1 cc of 0.01 MMC will be injected into the tenon at the beginning of the surgery. The rest of the operation is the same for both groups as standard trabeculectomy. Ophthalmic examination including IOP measurement will be performed at one, 3 and 6th month post surgery. Specular microscopy will be requested at final follow up visit. Bleb morphology will be scored according to Indian grading system at 3rd and 6th months post surgery.

The study aims to further understand glaucoma pathogenesis and progression by utilizing enhanced depth imaging optical coherence tomography to visualize and measure lamina cribrosa in vivo and segmentation technology to accurately delineate and measure boundaries of the retinal layers. Investigators will elaborate further on key concepts of lamina cribrosa thickness and trans-synaptic degeneration.

After implantation of an Ahmed glaucoma valve in patients with glaucoma, hyperencapsulation phase is an unwanted postoperative phenomenon, typically occurring with the free 3 months postoperatively. When this does occur, it is treated with aqueous suppressant eye drops. This study aims to determine if it is possible to reduce the rate of hyperencapsulation phase. Patients in the treatment group will receive aqueous suppressant eye drops before the hyperencapsulation phase starts. Treatment will be initiated once their intraocular pressure is above a pre-defined level, and will target a pre-defined range.

Antiglaucoma medication have been shown to induce subclinical conjunctival inflammation in a considerable proportion of glaucoma patients. Today, trabeculectomy still remains the gold standard as surgical treatment of medically uncontrolled glaucoma disease. However, this procedure is associated with variable possible complications, of which subconjunctival fibrosis is the most frequent one. The latter results in a non-functional filtering bleb. As a consequence, either additional interventions such as laser suture lysis, needling, bleb revision or additional IOP-lowering medication is necessary. Previous studies demonstrated a benefit of the use of topical steroids postoperatively in reducing inflammation and subsequent subconjunctival fibrosis. In this perspective, we will prospectively explore the usefulness of topical NSAID or corticosteroid therapy preoperatively as compared to placebo in subjects scheduled for first-time trabeculectomy, without interrupting topical antiglaucoma therapy. This will allow us to determine wether the impact of longterm topical antiglaucoma therapy on subclinical conjunctival inflammation which possibly result in postoperative fibrosis and bleb failure can be reversed by anti-inflammatory medication before filtering surgery.

The study hypothesis is that the Xal-Ease with increase patient compliance with XALATAN

Normal tension glaucoma (NTG) and chronic open angle glaucoma (COAG) occurring progressively with optimal conventional or intraocular pressure reducing surgery are still unsolved problems in ophthalmology. The investigators would like to investigate whether or not the composition of cerebrospinal fluid (CSF) surrounding the optic nerve (ON) in these patients is pathologic under certain conditions. They therefore compare the CSF taken during optic nerve sheath fenestration with the CSF taken during a lumbar puncture. The investigators' hypothesis is that, in patients with NTG and COAG, the composition of CSF surrounding the affected ON plays an important role in promoting progressive visual function loss.

Investigate degree of postoperative satisfaction in county level hospital glaucoma patients. Investigate the effect of educational intervention affect the degree of satisfaction in glaucoma patients. Investigate the effect factors of postoperative satisfaction.

The purpose of this study is to evaluate the usability of a medication management support system for glaucoma patients self-administering eye drops named iDropper. The iDropper system is a home-based ocular medication management system that reminds, instructs, dispenses, and records eye drop medication usage. The iDropper system will be evaluated among a cohort of glaucoma subjects self-administering eye drops for 4-weeks.
