A Investigator Masked Parallel Comparison of Tolerability of Combigan and Cosopt
The objective of this research study is to compare the tolerability and effectiveness of Combigan(brimonidine tartrate/timolol maleate) and Cosopt (dorzolamide hydrochloride)in the treatment of open angle glaucoma or ocular hypertension.
Patients between the ages of 40 to 90 years of age, that have been diagnosed with open angle glaucoma or ocular hypertension,including pseudo-exfoliation and pigmentary glaucoma with definitive glaucomatous optic disk cupping and/or glaucomatous visual field loss, who have been recieving a stable treatment regime for at least 4 weeks prior to the study initiation, with a Cosopt mono or a Prostaglandin + Cosopt combination are to be included in the study.Patients must have an IOP between 16 and 32 mmHg, with no readings above 35 mmHg at baseline.
Patients with any other form of glaucoma other than primary open angle glaucoma, with a gonioscopy measured angle grade of less than 2, with a visual field defect not of glaucomatous origen and previous cyclodestructive procedures will be excluded.The use of ocular non steroidal and anti-inflammatory topical agents which inhibit cyclooxygenase and prostaglandin analog synthesis,the use of glucocorticoid therapy, and hypersensitivity to any of the study components also precludes involvement in the study. Any ocular laser therapy within the past three months, ocular inflammation or infection in the past three months or any history of trauma in the last six months will also exclude enrollment in the study.

Medical and Biotech [MESH] Definitions
Glaucoma in which the angle of the anterior chamber is open and the trabecular meshwork does not encroach on the base of the iris.
Congenital open-angle glaucoma that results from dysgenesis of the angle structures accompanied by increased intraocular pressure and enlargement of the eye. Treatment is both medical and surgical.
Corneal Endothelial Cell Loss
Loss of CORNEAL ENDOTHELIUM usually following intraocular surgery (e.g., cataract surgery) or due to FUCHS' ENDOTHELIAL DYSTROPHY; ANGLE-CLOSURE GLAUCOMA; IRITIS; or aging.
Scattering, Small Angle
Scattering of a beam of electromagnetic or acoustic RADIATION, or particles, at small angles by particles or cavities whose dimensions are many times as large as the wavelength of the radiation or the de Broglie wavelength of the scattered particles. Also know as low angle scattering. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed) Small angle scattering (SAS) techniques, small angle neutron (SANS), X-ray (SAXS), and light (SALS, or just LS) scattering, are used to characterize objects on a nanoscale.
A form of glaucoma in which the intraocular pressure increases because the angle of the anterior chamber is blocked and the aqueous humor cannot drain from the anterior chamber.

Abstract Glaucoma, a leading cause of blindness worldwide, is currently defined as a disturbance of the structural or functional integrity of the optic nerve that causes characteristic atrophic change...
Background: The aim of this study was to evaluate diagnostic parameters and analysis of their advantages and limitations in early diagnostics of primary open-angle glaucoma (POAG). Cup/disc ratio (C/D...
PURPOSE: To study the characteristics of patients with advanced open-angle glaucoma. METHODS: A hospital-based retrospective study was performed. Advanced glaucoma was defined as visual acuity of 0.3...
