Your ophthalmologist has recommended you use a type of medicine called a miotic. This kind of medicine is helpful in treating glaucoma.

Glaucoma is a disease that affects your eye’s optic nerve, possibly leading to blindness. The optic nerve connects your eye to your brain so you can see. Glaucoma usually happens when fluid builds up in the front portion of your eye. Pressure increases in your eye, damaging the optic nerve and eventually stealing your sight.

Miotics make your pupil constrict (get smaller), and increase the amount of fluid that drains out of the eye. This helps lower eye pressure, and, hopefully, saves your vision.

Your ophthalmologist may have you take this miotic eye drop along with other glaucoma medicine.
