How does Betagan (levobunolol) treat glaucoma?

Betagan (levobunolol) is a beta-blocker that treats glaucoma by lowering pressure in the eye, or intraocular pressure (IOP). Elevated IOP increases the risk for optic nerve damage and vision loss.
Betagan decreases IOP by reducing the production of aqueous humor, which is the clear fluid that nourishes the lens and cornea. Betagan does not cure glaucoma but controls the pressure in the eye associated with the condition.
