Final answer:
Timolol is a medication used to treat glaucoma by reducing the production of fluid in the eye and lowering intraocular pressure. It helps prevent damage to the optic nerve and preserve vision in patients with glaucoma.
Step-by-step explanation:
Timolol is a medication commonly used to treat glaucoma. It works by reducing the production of fluid in the eye, known as aqueous humor, which helps to lower the intraocular pressure. Timolol is a non-selective beta-blocker that blocks beta receptors in the eye, resulting in decreased fluid production. By reducing the intraocular pressure, timolol helps to prevent damage to the optic nerve and preserve vision in patients with glaucoma.
