Active clinical trials for "Glaucoma"

To compare the safety and effectiveness between ologen collagen matrix and mitomycin-C (MMC) in glaucoma surgery. The ologen collagen matrix implantation procedure is same as traditional trabeculectomy except implant the ologen collagen matrix on the top of sclera flap after one loose stich the sclera flap. The MMC application is as the standard.

The purpose of this study is to compare the safety and IOP-lowering efficacy of a fixed combination of Travoprost/Brinzolamide Ophthalmuc Suspension dosed BID and QD, to TRAVATAN dosed QD and a Vehicle dosed BID in patients with open-angle glaucoma or ocular hypertension.

The purpose of this study is to assess the safety and efficacy of transitioning uncontrolled glaucoma patients to DuoTrav from other mono or adjunctive therapies.

Evaluate the effectiveness of dorzolamide-timolol (Cosopt®) as first line therapy in reducing intraocular pressure in patients with untreated Open angle glaucoma (OAG) or Ocular hypertension (OH).

Several lines of evidence suggest now that ocular perfusion abnormalities may contribute to the progression of glaucoma. It has been hypothesised that increased endothelin-1 plasma levels, as seen in patients with glaucoma, may be related to these alterations in ocular blood flow. We could show in recent experiments that administration of ET-1 decreases ocular blood flow, whereas blocking of the ET-A receptors do not affect basal vascular tone in healthy subjects. In the current study we set out to evaluate the effect Bosentan, a non-selective ETA-receptor antagonist in patients with open-angle glaucoma. This should allow us to test the hypothesis that administration of an ET-1 receptor antagonist increases ocular blood flow in patients with glaucoma. Investigations will be done with a retinal vessel analyzer to determine retinal vessel cross-sectional diameters, with laser Doppler flowmetry and laser Doppler velocimetry to determine subfoveal macular blood flow and optic nerve head blood flow and with laser interferometric measurements to determine fundus pulsation amplitude in the macula. The intraocular pressure will be measured with applanation tonometry. This will be assessed at baseline and in response to peroral application of Bosentan or placebo. The study objective is therefor, to evaluate the contribution of ET-1 to ocular blood flow dysregulation in patients with open-angle glaucoma.

The purpose of this study is to investigate if changes in ocular signs and symptoms occur in patients with ocular hypertension or glaucoma when they switch from latanoprost 0.005% (Xalatan) to preservative free Tafluprost eye drops.

The purpose of this study is to compare the safety & effectiveness of the two types of cataract and glaucoma surgeries. Results from this study may improve the surgical and post surgical management and long term management of patients with these conditions in the future

The purpose of this study is to assess the safety and efficacy of switching to ELAZOP from prior pharmacotherapy in patients with open-angled glaucoma.

This was a prospective, double-masked, 15-month clinical trial comparing efficacy of phacoemulsification alone to combined phacoemulsification and implantation of the iStent® trabecular micro-bypass stent in patients with primary open-angle glaucoma.

The purpose of this study is to determine the effect of artificial tears preserved with Benzalkonium Chloride (AT-BAK) on the IOP response to the L-PPDS and to evaluate the safety of the L-PPDS in subjects with OH or OAG following treatment.
