What are eyedrops for glaucoma?

Medically reviewed by Carl J. May Jr., MD · American Board of OphthalmologyLast updated June 2026
Transcript

If you are diagnosed with glaucoma, your doctor may prescribe eye drops to control pressure in your eye. These drops are applied onto the surface of the eye and may cause stinging or burning. Eye drops for treating glaucoma work in two ways. First they lesson the amount of aqueous fluid the ciliary body of your eye produces. Second, the drops may allow more fluid to drain out of the eye more easily. Sometimes, drops alone may not be able to treat glaucoma.

What’s in this video

Prescription drops are usually the first treatment for glaucoma. They lower pressure either by reducing the fluid your eye makes or by helping it drain — and while they may briefly sting, using them faithfully every day is what protects your vision.
