“Glaucoma medication, in the form of eye drops or pills, is the most common early treatment for glaucoma. Medications work by lowering eye pressure, either by slowing the production of aqueous humor fluid or by improving the drainage of fluid from the eye.

Prior vision loss from glaucoma is not reversible with treatment or surgery.”
