眼心反射的再认识

眼心反射（OCR）在眼科手术中的发生率高达90％，而大多数临床医师认为OCR的表现仅仅是心动过缓、心律失常，却忽略了其他系统的表现，如：“眼肺反射”（ORR）、“眼胃反射”，也有人称之为“眼一呕吐反射（OER）”等。OCR并非仅仅为眼科手术的并发症，其在窦房结内镜手术过程中和治疗进行性三叉神经痛的过程中也可发生，但对此现象的描述以临床表现报道居多。目前的研究有助于提高临床医师对OCR的认识，对OCR的眼胚胎、解剖、生理、电生理、发生机制等研究进展进行综述，提出应重新认识OCR的本质特征，认为其名称为眼迷走神经反射（OVR）更为合理。

Recognition of oculocardiac reflex

The oculocardiac reflex (OCR) occurs in up to 90% of ophthalmological surgeries,while most of the clinicians consider the performance of OCR is just bradycardia and arrhythmia and therefore ignore other system manifestation such as oculorespiratory reflex( ORR) and oculo-emetic reflex(OER),and so on.OCR appears not only in ophthalmological surgeries,and it also occurs during the endoscopic sinus surgery.A unstable bradycardia associated with stimulation of the mandibular division of cranial nerve V during trigeminal neuralgia pain treatment is also reported.This phenomenon is mostly introduced only as clinical manifestations.Therefore,it is helpful for us to understand the essential characteristic of OCR.The embryonic,anatomy,physiology and electrophysiology were reviewed in this article and thought to term it as oculovagal reflex is more comprehensive.
