ABSTRACT
We describe an atypical presentation of aberrant regeneration of the 3rd cranial nerve causing vision changes with ocular motility. Abnormal communication between axons destined for the medial rectus and those destined for muscles involved in the accommodative response resulted in simultaneous pupil constriction and myopic shift of approximately 2.5 diopters with adduction. While there have been several reports of this pupillary response (Czarnecki sign), no cases have documented the change in refraction from ciliary muscle involvement.
