Active clinical trials for "Glaucoma"

This study aims to look into the change of the corneal biomechanical properties in patients undergoing insertion of the Ex-PRESS mini shunt or trabeculectomy for medically uncontrolled glaucoma

Glaucoma is a progressive optical neuropathy, generally associated with ocular hypertension. The treatment aims to stabilize the visual field deficiencies by lowering the intraocular pressure. Due to the fluctuation of the visual field test and re-test measures, the European recommendations are to obtain 6 visual field tests in 2 years (or one every 4 months) in order to know if the pathology is progressing despite the current treatment (or if the treatment is necessary, in cases of intraocular hypertensions). The lack of ophthalmologists renders the monitoring of a beginning glaucoma, rarely compatible with the present recommendations. It is therefore crucial to evaluate new therapeutic alternatives, when faced to a decreasing medical demography and an increase the patient's needs. This study should allow to validate the possibility to delegate monitoring tasks to orthoptists during glaucoma surveillance. To organize the delegation of this surveillance to orthoptists would permit a better distribution of the ophthalmologist's activities.

When a patient with glaucoma who has a pressure that is too high and causing damage to their vision, despite receiving the maximum amount of medication that can be tolerated, the decision is made to have glaucoma surgery. Trabeculectomy is the most common form of glaucoma surgery used to treat open angle glaucoma. During trabeculectomy, an opening is created in the eye and partially covered with a flap of tissue. This new opening allows fluid to drain out of the eye bypassing the clogged drainage channels that are malfunctioning in patients with glaucoma. Studies have found that trabeculectomy significantly reduces vision loss and lowers eye pressure. However, many people need another trabeculectomy or other glaucoma surgery because the surgery may fail either early or much later because the body closes the drain created by the surgeon. The surgery is also less likely to work in patients with darker pigmentation, children who have congenital glaucoma, people with difficult to control glaucoma with new blood vessels growing on the iris, diabetes or persons with prior eye surgery. As a result, the investigators need to find ways to improve the longterm survival of trabeculectomy surgery in all patients.

The purpose of this study is to test if latanoprost punctal plugs will reduce eye pressure in subjects with ocular hypertension or open-angle glaucoma.

Prospective, unmasked, randomized evaluation of the iStent in patients with primary open-angle glaucoma. Patients will be randomized to one of two groups: 1) iStent, or 2) medication.

The purpose of this study is to determine whether reducing inflammation of the surface of the eye with topical Restasis after glaucoma surgery will improve surgical outcomes and increase patient comfort.

The objective of this study is to demonstrate the ability of the Hydrus Implant to lower intraocular pressure in glaucoma patients undergoing cataract surgery.

The objective of this Phase 2 study is to evaluate whether the Bimatoprost Ocular Insert is non-inferior to that of timolol ophthalmic solution (0.5%) at 12 weeks.

Double-masked, randomized, multi-center, dose-response, active-controlled parallel-comparison of AR-13324 to latanoprost

The purpose of this study is to assess and compare the mechanical angle opening in patients with angle closure due to a plateau iris configuration (elevated iris) using phacoemulsification combined with endoscopic cycloplasty versus treatment with phacoemulsification alone.
