What is "eye drop"

alt. medicine to be administered to the eyes. n. medicine to be administered to the eyes.

Eye drops are saline-containing drops used as an ocular route to administer. Depending on the condition being treated, they may contain steroids, antihistamines, sympathomimetics, beta receptor blockers, parasympathomimetics, parasympatholytics, prostaglandins, nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, antifungal, or topical anesthetics. Eye drops sometimes do not have medications in them and are only lubricating and tear-replacing solutions.

Eye drops have less of a risk of side effects than do oral medicines, and such risk can be minimized by occluding the lacrimal punctum, (i.e. pressing on the inner corner of the eye) for a short while after instilling drops.Eye drops are also used for stopping itching and redness of the eyes.
