Horner's syndrome consists of miosis (constriction of the pupil), ptosis (drooping of the upper eyelid), anhidrosis (absence of sweating of the face), and enophthalmos (sinking of the eyeball into the eye socket).[1][2][3]  It is caused by injury to the sympathetic nerves of the face. In rare cases, Horner's syndrome is congenital (present from birth) and associated with a lack of pigmentation of the iris (colored part of the eye).[1]
