Active clinical trials for "Glaucoma"

This study will assess any side effects that may occur when QPI-1007 is injected into the eye in subjects with acute primary angle-closure glaucoma, as well as how long it takes for the body to clear the drug. This study will also test whether QPI-1007, injected into the eye, helps prevent both structural damage of the nerve tissue in the eye and the loss of visual function in subjects with acute primary angle-closure glaucoma.

Glaucoma topical eye medications, when adhered to, are effective at controlling disease progression. Yet evidence shows that many glaucoma patients have incomplete adherence to medications, with disease progression resulting in significant costs to the patient and health system. Through the approach of value pricing, a link can be made between non-adherence and its resulting costs by granting subsidies to adherent patients for their medications and physician visits. This 6-month randomized controlled trial among 100 glaucoma patients from the Singapore National Eye Centre aims to test the extent to which value pricing can improve medication adherence.

Evaluate the relative efficacy and tolerability of Alphagan P compared to Trusopt as adjunctive therapy

The investigators aim to evaluate the efficacy of the new Optical Coherence Tomography based Angiography (OCT-A) softwares in the diagnosis and management of glaucoma.

Glaucoma is among the leading causes for blindness in the western world. Elevated intraocular pressure (IOP) has been identified as the most important risk factor. However, some patients progress despite adequate IOP lowering while some subjects with elevated IOP never develop glaucoma. Other patients develop glaucoma although IOP measurements were always in the normal range. Therefore, other factors must be involved. In the last years, studies using MRI have been performed and evidence has accumulated that also changes in retrobulbar structures are present, in particular in the lateral geniculate nucleus and the visual cortex. However, these studies were limited by the low spatial resolution of the MRI instruments used.

In patients with Glaucoma, Xalost S or Xalatan or Taflotan-S are administered for 12 weeks. After 12 weeks, among them, Xalatan administration group are switched to Xalost S or Taflotan-S. Extension study period is 8 weeks. To compare effect (ocular surface damage) and safety of preservative-free Latanoprost/Tafluprost to Benzalkonium chloride-preserved Latanoprost in primary open angle glaucoma or normal tension glaucoma.

Prospective, multi-center, single-arm clinical trial to evaluate the safety and effectiveness of the Glaukos® Trabecular Micro-Bypass System Model iS3 (three stents per study eye) in subjects with refractory glaucoma.

A 6-month, parallel-group study of the safety and efficacy of tafluprostin for Chinese patients with posttrabeculectomy residual primary angle-closure glaucoma or posttrabeculectomy residual primary open angle glaucoma.

Traditional ciliary body photocoagulation treatment uses the photocoagulation of long-wavelength laser to destroy the ciliary body tissue that can produce aqueous humor. Therefore, it is a kind of palliative treatment which has proved efficacy but causes great pain to patients. The "ultrasonic glaucoma treatment instrument" produced by French EYE TECH CARE company is referred to as EyeOP1. It uses high-intensity focused ultrasound technique to make target part of the ciliary coagulative necrosis, reduce the production of aqueous humor and thereby lower the intraocular pressure. EyeOP1 is ergonomic and suitable for the human eye, making the treatment process more accurate, simple and fast.

Intraocular pressure (IOP) is the most important modifiable risk factor to prevent and delay progression of glaucoma. IOP reduction has been proven to delay the onset and progression of glaucoma, and uncontrolled IOP is constantly associated with progression of visual field loss. Medical therapy is the first line in IOP reduction for Primary Open Angle Glaucoma (POAG). It is a known fact that glaucoma patients often require addition of a second antiglaucoma medications when disease progresses or tachyphylaxis occurs. It was reported that more than 50% of patients require 2 or more medications to achieve optimum IOP control. Nevertheless, compliance and adherence are often impaired with multiple-drug therapy. Combining two ocular hypotensive agents in one bottle may help patients adhere to therapeutic regimen by reducing the number of medications used and the total number of doses administered.
