Eye drops are saline-containing drops used as a vector to administer medication in the eye. Depending on the condition being treated, they may contain steroids (e.g. dexamethasone), antihistamines, sympathicomimetics, beta receptor blockers, parasympathicomimetics (e.g. pilocarpine), parasympatholytics (e.g. tropicamide or atropine), prostaglandins or non-steroidal anti-inflammatory drugs (NSAIDs). Eye drops sometimes don't have medications in them and are only lubricating and tear-replacing solutions, and they can also contain anti-redness and similar chemicals.

Scientists found that pressure-lowering eyedrops reduced by more than 50 percent the development of primary open-angle glaucoma, the most common form of glaucoma and one of the nation's leading causes of vision loss.
Elevated pressure in the eye, a common condition affecting three to six million people in the United States, is thought to be the leading risk factor for development of open-angle glaucoma.
Scientists found that eyedrops used to reduce pressure inside the eye were effective in delaying the onset of primary open-angle glaucoma.
