The reflex is mediated by the connection between the ophthalmic branch of the trigeminal nerve and the vagus nerve. Most commonly, the reflex induces bradycardia, though it has also been …

The oculocardiac reflex, also known as Aschner phenomenon, Aschner reflex, or Aschner–Dagnini reflex, is a decrease in pulse rate associated with traction applied to …

A typical oculocardiac reflex (OCR) is a moderate trigemino-vagal bradycardia elicited by tension on an extraocular muscle (EOM) during strabismus surgery; however, many other orbital …

The oculocardiac reflex is defined as a vagally mediated reflex triggered by factors such as traction of the extra-ocular muscles, direct pressure on the globe, or ocular trauma, typically …

Jul 22, 2025 · The oculocardiac reflex (OCR) is an involuntary physiological response that slows the heart rate. This reflex occurs when pressure is applied to the eye or its surrounding …

Nov 25, 2025 · The OCR, also known as the Aschner reflex or trigeminovagal reflex, results in bradycardia, and sometimes more significant arrythmias such as asystole, when pressure is …

Jan 20, 2023 · Oculocardiac reflex (OCR) is mediated by the trigeminal and vagus nerves. OCR usually presents as sinus bradycardia and is commonly seen during strabismus surgery with …

The Oculocardiac Reflex (OCR) is a well-documented physiological phenomenon in ophthalmic surgery, characterized by a sudden decrease in heart rate in response to ocular manipulation.

The oculocardiac reflex is a decrease in pulse rate associated with traction on extraocular muscles and compression of the eyeball, often occurring during eye surgery.

Sep 19, 2022 · The oculocardiac reflex (OCR), also known as the Aschner reflex or trigeminovagal reflex (TVR), was first described in 1908 as a reduction in heart rate secondary …
