The Study of the Oculocardiac Reflex

ABSTRACT

Ophthalmologists now realize the importance of the oculocardiac reflex from ocular manipulation. The occurrence of cardiac disturbances has been recognized since 1908. Several authors have believed the mechanisms of the reflex affecting the pulse rate. the conduction system and myocardial contractibility of the heart. For the purpose of the recognition of this reflex, authors performed ocular compression and muscle traction after atropine injection or retrobulbar anesthesia in 135 persons. The results were noted that the reflex is blocked by intravenous atropine injection or retrobular anesthesia. while not by subconjunctival anesthesia or intramuscular atropine injection.
