mydriasis, mi-drī′a-sis, n. morbid dilatation of the pupil of the eye.
Visual acuteness on both sides 5/12, the left slightly better than the right; emmetropia in mydriasis by atropine.
mydriasis does not always occur, and when it does, is much less than with cocaine.
At the same time there is a certain amount of mydriasis, but this is less pronounced than that produced by atropine.
