Oculocardiac reflex during excision of periorbital tumor--a case report.

: The occurrence of oculocardiac reflex causing severe bradycardia and hypotension during the excision of a large, hemorrhagic, periorbital tumor in a 66 year old male is presented. The reflex occurred despite complete destruction of the eye by the tumor. Intravenous atropine, 0.5 mg, restored both the heart rate and blood pressure and prevented further occurrence of the reflex during the rest of the operation.
