Filter by:This study compares the efficacy and tolerability/comfort of brimonidine/timolol and dorzolamide/timolol in patients with open-angle glaucoma or ocular hypertension. In an investigator masked randomization process, each subject is allocated to recieve either brimonidine/timolol or dorzolamide/timolol as fixed-combination monotherapy or as an adjuctive to a prostoglandin analogue for a period of 12 weeks. After screening, patient returns at baseline, Month 1, and Month 3 for ophthalmic evaluations.

In an investigator masked randomisation process, each subject is allocated to received either brimonidine/timolol or dorzolamide/timolol as fixed-combination monotherapy or as an adjunctive to a prostaglandin analogue for a period of 12 weeks.

The study objective is to compare IOP and safety outcomes based on plug placement (upper or lower puncta).
The purpose of this study is to determine if the Punctal Plug Delivery System is safe and effective in controlling intraocular pressure in patients with ocular hypertension or open-angle glaucoma.
A 10 week evaluation, crossover design study including a 3 week washout period between treatments, to determine the effects of Combigan® (fixed combination brimonidine tartrate 0.2%/timolol maleate 0.5%) and Cosopt® (fixed combination dorzolamide hydrochloride-timolol maleate ophthalmic solutions) on ocular blood flow as measured by retrobulbar blood flow.
A three-month evaluation comparing the safety and efficacy of a fixed combination of 0.2% brimonidine tartrate/0.5% timolol maleate with that of latanoprost 0.005%, a prostaglandin analogue in glaucoma or ocular hypertension subjects
Glaucoma, one of the most common causes of blindness, is associated with increased intraocular pressure (IOP) and optic nerve head ischemia. Nitrovasodilators are discussed in the treatment of glaucoma. Nitrates relax smooth muscle cells in the vasculature by liberating the vasodilator nitric oxide. The IOP lowering potential and the vasodilator action in retinal and choroidal vessels of nitrates is still a matter of controversy. Previous studies on the ocular hemodynamic effects of nitrates showed partially contradicting results. In addition the IOP lowering effect of nitrates is still unclear. However, recent studies show that long acting nitrates may preserve optic nerve deterioration and visual field loss. Therefore, the role of nitrovasodilators in control of ocular blood flow and intraocular pressure has to be elucidated. For this purpose the investigators plan to test the hypothesis that nitrovasodilators improve ocular blood supply to the optic nerve head at doses which do not affect systemic hemodynamics.
The study will evaluate the safety and efficacy of AGN-210669 ophthalmic solution in comparison with AGN-210669 vehicle and bimatoprost ophthalmic solution dosed once-daily each morning, in subjects with ocular hypertension or primary open-angle glaucoma. Subjects will be followed for 2 weeks.
This study compares patient symptoms and anterior segment safety in patients treated with timolol hemihydrate, generic timolol gel forming solution or timolol maleate.
