Timolol ophthalmic is used to treat open-angle glaucoma and glaucoma caused by another disease of the eye (secondary glaucoma).
How it works: Timolol is a beta-blocker which acts on receptors in the blood vessels in the eye causing them to constrict. This reduces the amount of fluid (aqueous humor) that passes out of the blood vessels into the eyeball. Timolol also blocks the area of the eye that actively produces aqueous humor.
Cautions: The dropper opening is sterile, so don’t touch it to any surface, including eyes or hands. If it becomes contaminated, it may cause an infection in the eye.
