Oculocardiac Reflex and Autonomic Modulation in a Broad-Snouted Caiman (Caiman latirostris)

Acta Scientiae Veterinariae
Background: The oculocardiac reflex (OCR) is a neurophysiological response mediated by the vagus nerve, triggering changes in heart rate and rhythm in response to pressure applied to the ocular globe.

White-Eyed Orbital Blowout Fracture With Oculocardiac Reflex Secondary to Extraocular Entrapment in a Pediatric Patient

The Journal of craniofacial surgery (Print), 2022
White-eyed orbital blowout fractures in the pediatric population can present with acute onset diplopia, ophthalmalgia, and abnormal duction. These findings are attributed to the tendency of younger bone to break and reapproximate owing to greater ...

Comparing a single injection peribulbar block with articaine 4% vs lidocaine 2% vs mepivacaine 3% for prevention of oculocardiac reflex in children undergoing strabismus surgery under general anesthesia: a randomized clinical trial

Anaesthesia, Pain & Intensive Care
Background & objective: Peribulbar block is used to prevent oculocardiac reflex (OCR) in children in addition to general anesthesia (GA). We compared GA with a single peribulbar block using articaine 4%, lidocaine 2%, or mepivacaine 3% for the prevention

OCULOCARDIAC REFLEX IN OPHTHALMIC AND NON-OPHTHALMIC SURGERY: EPIDEMIOLOGY, MECHANISMS, PREVENTION AND MANAGEMENT

Lumen et Virtus
Introduction: The oculocardiac reflex is a trigeminovagal response that may occur during ophthalmic and non-ophthalmic procedures involving manipulation of orbital structures, leading to bradycardia, arrhythmias, or hemodynamic instability.

Intravenous dexmedetomidine augments the oculocardiac reflex

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2018
We reported that premedication with nasal dexmedetomidine was associated with a more intense oculocardiac reflex (OCR). In this study we performed an intrasubject, intravenous comparison to test our hypothesis that this alpha-adrenergic agonist potentiates the trigemino-vagal reflex.OCR (greatest change heart rate/baseline heart rate) was prospectively

Stimuli factor of muscular receptors, extraocular muscles and oculocardiac reflex (OCR)

Physiology
Introduction: The oculocardiac reflex (OCR) was first described in 1908 as a reduction in heart rate secondary to direct pressure on the eyeball. OCR has been described during ophthalmologic procedures.

A Comparison Between the Effects of Peribulbar and Sub-tenon Blocks Combined with General Anesthesia on the Incidence of Oculocardiac Reflex during Pediatric Strabismus Surgery: A Double-Blinded Randomized Control Study

Bali Journal of Anesthesiology
Pediatric strabismus surgeries have frequently been linked to the occurrence of oculocardiac reflex (OCR). This study aimed to assess the efficacy and safety of peribulbar and sub-tenon blocks on the occurrence of OCR during pediatric strabismus ...

The Oculocardiac Reflex in Identical Twins

Archives of Ophthalmology, 1988
To the Editor. —The oculocardiac reflex (OCR) is a slowing of the heart rate due to ocular manipulation and particularly tension on the extraocular muscles. The response is variable from one patient to the next and rarely produces profound bradycardia.

Oculocardiac Reflex in the Anophthalmic Socket

Ophthalmic Surgery, Lasers and Imaging Retina, 1992
ABSTRACT The oculocardiac reflex occurred in a patient with an anophthalmic socket undergoing surgery for inferior fornix shortening and laxity of the lower lid. This reflex occurs only rarely in anophthalmia; it has not been previously reported during socket surgery.
