Which one is better to lower ocular pressure in open angle glaucoma. 5 mg amlodipine (calcium channel blocker) or 5 mg bystoilc ( beta blocker).?

Beta Blocker: The effect is minor, but if your cardiologist is considering either one as equal for your blood pressure or heart condition a beta blocker will boost the eye drops just a little bit.

Both/neither: They both "help" but neither is considered a primary treatment for glaucoma.

Neither: Most medications used to treat high blood pressure are not indicated in the treatment of open angle glaucoma.
