Less likely: Trauma to the iris causes dilation. This is most likely from sphincter tear at the pupillary margin of the iris.

No: It has no effect on the iris muscle, other than slight dilation that is temporary.

Brimonidine blunts the mydriatic effect at night lessening glare from lights, also causes mild miosis in daylight.
