Trauma to eye, one pupil slightly larger than other. optho prescribed brimonodine tartrate for short-term. will this fix damaged muscle?

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.
