Eye drops work to reduce intraocular pressure through two primary mechanisms: decreasing the production of fluid within the eye or improving the drainage of existing fluid. While these medications cannot reverse damage that has already occurred to the optic nerve, they are effective at preventing further progression of glaucoma. Since glaucoma is a chronic, lifelong condition, most patients will need to continue using their prescribed eye drops indefinitely to maintain healthy eye pressure levels.

It is very important to use your eye drops exactly as you’re advised. You will need to use them every day, and some types must be used once, twice, or three times a day, depending on the medicine. Using your drops regularly helps stop glaucoma from getting worse and protects your vision.
