Tropicamide ophthalmic causes muscles in the eye to become relaxed. This dilates (widens) the pupil so that it does not contract (narrow) when your doctor shines an examination light into your eye. Tropicamide ophthalmic is used to dilate the pupil for an eye examination or other diagnostic procedure. Tropicamide ophthalmic may also be used for purposes other than those listed in this medication guide.
Mydriacyl (tropicamide ophthalmic) is used to dilate pupils before examinations. It is used to treat iritis, iridoyclitis, keratitis and swelling of certain muscles in the eyes. It also decreases inflammation in the eye. If you have a question about what this drug treats please check with your physician.
