This study will evaluate the safety and efficacy of PF 03187207.
Patients with glaucoma or ocular hypertension currently being treated with latanoprost 0.005%, and in need of additional IOP lowering will be randomized to receive either brimonidine 0.1% or brinzolamide 1% three-times daily as adjunctive therapy to latanoprost 0.005%
Patients with glaucoma or ocular hypertension currently being treated with latanoprost 0.005%, and in need of additional IOP lowering, will be randomized to receive either bimatoprost 0.03% or travoprost 0.004% in place of latanoprost 0.005%
We hypothesize that glaucoma patients demonstrate an impaired retinal vascular response to the flicker stimulus, and that this disturbance is predictive of the progression of glaucomatous damage. The response of a major temporal superior and inferior retinal artery and vein to a 60 seconds 12.5 Hz flicker light stimulation in 50 glaucoma patients, 50 ocular hypertensives and 50 controls (using the Retinal Vessel Analyzer) and to investigate how intraocular pressure relates to neurovascular coupling. In addition, 50 glaucoma patients and 50 ocular hypertension patients will be followed for 3 years for functional (visual field, automated perimetry with Octopus device) and morphological (retinal nerve fiber layer thickness, Optical Coherence Tomography Stratus ocular coherence tomography (OCT) device) glaucomatous damage progression, in order to test the predictive power of the retinal vascular flicker response for glaucoma progression.

Glaucoma is a chronic disease defined by characteristic changes in the optic nerve associated initially with loss of peripheral vision and is treated by lowering intraocular (inside the eye) pressure. It has been reported that noticeable changes to the optic nerve caused by glaucoma may occur several years before changes in vision are noticed. Since changes to the optic nerve and other eye structures due to glaucoma are irreversible, it is important to develop tools for the earliest possible detection of changes due to glaucoma. The Heidelberg Retina Tomograph (HRT) is a device that is used to produce a three-dimensional map of the optic nerve and retina, and can be used to detect changes in the optic nerve and retina over time. In previous studies, it has been shown to be useful for the detection of changes due to glaucoma. However, the HRT when compared to other techniques to evaluate the optic nerve such as stereophotography, was found to only somewhat agree. The current study will compare HRT to stereophotography to determine how good each one is at looking and documenting changes in the optic nerve over time due to glaucoma. Using HRT to initiate early topical medication or to change management requires knowing how well HRT results predict the development of visual loss. Accordingly, the results of this study may affect the management of glaucoma patients by optimizing the follow-up of people with this condition and by initiating appropriate and more individualized treatments. Early treatment is crucial for preventing further visual loss in patients with glaucoma or ocular hypertension (high pressure inside the eye).
