title: Transient oblong anisocoria and orbital surgery.
abstract: We present a rare case of transient oblong (segmental) anisocoria occurring at the time of limited orbital surgery. Observation of this previously undescribed phenomenon prompted us to review the relevant anatomy and physiology of the iris and the pharmacokinetics of lidocaine as it pertains to surgery in the region of the eyelids and the orbit.
