A
Feedback:
Timoptic is a beta-blocker that is used topically to decrease the flow rate of aqueous humor in the eye. As flow rate decreases, the intraocular pressure decreases. IOP of 12 to 21 mm Hg is within normal range. Reduced peripheral vision, halos around lights, and blurred vision are all symptoms of open-angle glaucoma. Nausea and vomiting are more likely to occur with acute angle-closure glaucoma.
