Comparison of Brimonidine Purite, Dorzolamide, and Brinzolamide as Adjunctive Therapy to Prostaglandin Analogs
The purpose of this study is to compare the efficacy of brimonidine Purite, dorzolamide, and brinzolamide in reducing intraocular pressure when added to prostaglandin analog therapy (bimatoprost, latanoprost, or travoprost) in patients with glaucoma or ocular hypertension.

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.
The purpose of the study is to determine whether combination of brinzolamide and brimonidine is safe and effective in patients with open-angle glaucoma or ocular hypertension.
