NCT ID: NCT01298635 Completed - Cataract Clinical Trials

Comparison of Phacotrabeculectomy and Trabeculectomy in the Treatment of Primary Angle-closure Glaucoma (PACG)

Start date: January 2005
Phase: N/A
Study type: Interventional

Primary angle closure glaucoma (PACG) is caused by contact between the iris and trabecular meshwork, which in turn obstructs outflow of the aqueous humor from the eye. This contact between iris and trabecular meshwork (TM) may gradually damage the function of the meshwork until it fails to keep pace with aqueous production, and the pressure rises, and at last the optic nerve is damaged, the vision may be lost in some severe cases. Therefore, ocular pressure reduction is the key to treat the disease and prevent blindness. Trabeculectomy is the most common conventional surgery performed for glaucoma. This allows fluid to flow out of the eye through this opening, resulting in lowered intraocular pressure(IOP) and the formation of a bleb or fluid bubble on the surface of the eye. Cataract surgery is common in the elderly. Cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract. Cataract extraction includes intracapsular cataract extraction, extra capsular cataract extraction & phacoemulsification, and phacoemulsification is the preferred method. It has been reported that IOP reduction could occur in cataract patients with PACG after the cataract surgery. For some cases with PACG, such IOP reduction may be insufficient for neuronal protection, and many patients still require glaucoma medication and incisional surgery such as trabeculectomy to control IOP. In such cases, a combined cataract-glaucoma procedure (phacotrabeculectomy) is a reasonable option. In keeping with this concept, previous studies have shown that phacotrabeculectomy could effectively and simultaneously reduce IOP and improve vision in patients with a coexistence of PACG and vision-threatening cataract. However, phacotrabeculectomy may heighten inflammatory response, result in a higher frequency of postoperative complications such as hyphema and fibrin in the anterior chamber, endophthalmitis, and increased scarring of the filtering bleb. Thus, it is unclear whether phacotrabeculectomy is as effective and safe as trabeculectomy in lowering IOP for PACG patients. In the present study, the investigators compared the efficacy and safety of phacotrabeculectomy and trabeculectomy in patients with coexisting PACG and cataract.

NCT ID: NCT01297920 Completed - Ocular Hypertension Clinical Trials

Three Month Efficacy/Safety Study With a 3-Month Safety Extension of Brinzolamide 1%/Brimonidine 0.2% vs. Brinzolamide 1% or Brimonidine 0.2%

Start date: March 2011
Phase: Phase 3
Study type: Interventional

The purpose of this study was to evaluate the safety and efficacy of a new ophthalmic suspension (Brinz/Brim) in lowering intraocular pressure (IOP) relative to its individual active components in subjects with open-angle glaucoma and/or ocular hypertension.

NCT ID: NCT01297517 Completed - Ocular Hypertension Clinical Trials

Efficacy and Safety Study of Brinzolamide 1%/Brimonidine 0.2% vs. Brinzolamide 1% and Brimonidine 0.2%

Start date: February 2011
Phase: Phase 3
Study type: Interventional

The purpose of this study was to evaluate the efficacy and safety of a fixed combination of Brinzolamide/Brimonidine in lowering intraocular pressure (IOP) relative to each of its individual active components in patients with open-angle glaucoma and/or ocular hypertension.

NCT ID: NCT01292460 Completed - Ocular Hypertension Clinical Trials

Tafluprost-Timolol Preservative-free Fixed Dose Combination (FDC) Superiority Study Against Monotherapies

Start date: February 2011
Phase: Phase 3
Study type: Interventional

The purpose of this study is to compare the efficacy and safety of the preservative-free fixed tafluprost-timolol combination to those of tafluprost and timolol alone. This study will enroll patients who have ocular hypertension or glaucoma and who are using timolol or prostaglandin. The study medication period is 6 months, but the primary evaluation of efficacy is done at 3 months.

NCT ID: NCT01291108 Completed - Ocular Hypertension Clinical Trials

Safety and Efficacy of AGN-210669 Ophthalmic Solution Compared With Bimatoprost Ophthalmic Solution in Patients With Open-Angle Glaucoma or Ocular Hypertension

Start date: April 2011
Phase: Phase 2
Study type: Interventional

This study will evaluate the safety and efficacy of AGN-210669 ophthalmic solution compared with bimatoprost ophthalmic solution (Lumigan®) as monotherapy and adjunctive therapy in patients with primary open-angle glaucoma or ocular hypertension.

NCT ID: NCT01287442 Completed - Glaucoma Clinical Trials

Evaluation of Filtering Blebs Using the "Wuerzburg Bleb Classification Score" Compared to Other Clinical Findings, e.g. the Intraocular Pressure (IOP)

Start date: January 2009
Phase: Phase 4
Study type: Observational

It is well established to assess the functionality of a filtering bleb by intraocular pressure (IOP), either as an absolute value or as a percent reduction, and by the need of additional antiglaucoma drugs. It is also possible to evaluate the appearance of a bleb by a clinical score, e.g. the "Wuerzburg bleb classification score" (WBCS). The purpose of this study was to find out whether there is a correlation between clinical findings, in particular IOP and the WBCS. 100 eyes within two years after trabeculectomy were included into the study. Using colour photographs the filtering bleb was evaluated according to the WBCS from two different examiners, both on different levels of clinical experience. WBCS = 1 indicates poor bleb appearance, WBCS = 15 indicates optimal bleb appearance. At the same time, clinical findings like intraocular pressure, best corrected visual acuity, slit lamp biomicroscopy and medical history were taken by another examiner. - Trial with surgical intervention

NCT ID: NCT01282346 Completed - Glaucoma Clinical Trials

SOLX Gold Shunt for Refractory Glaucoma

Start date: January 2011
Phase: N/A
Study type: Interventional

To establish the clinical performance of the SOLX Gold Shunt for its ability to reduce intraocular pressure (IOP) in eyes with refractory glaucoma where medical and conventional surgical treatments have failed.

NCT ID: NCT01281020 Completed - Ocular Hypertension Clinical Trials

Adherence With Fixed Versus Unfixed Glaucoma Therapy

Start date: May 2009
Phase:
Study type: Observational

A 6-month, parallel, non-interventional trial investigating the level of adherence and the impact of dosing in open-angle glaucoma patients who receive either unfixed therapy with latanoprost once in the evening and timolol twice daily, or latanoprost/timolol fixed combination therapy once in the evening. All patients participating in this observational study will be monitored for their adherence with the use of Medication Event Monitoring System (MEMS). At the end of treatment periods treatment satisfaction will be assessed with selected questions from the Treatment Satisfaction Survey-Intraocular Pressure survey. This study will monitor objectively, for the first time, adherence and intraocular pressure control with fixed versus unfixed therapy. Finally it will help us to elucidate the impact of dosing (once-a-day versus three-times-daily) on the level of adherence in glaucoma.
