A surgical patient develops sudden marked bradycardia during traction on the eye or extraocular muscles. Which reflex most likely explains this response?
Correct answer: B. Oculocardiac reflex
- A. Pupillary light reflex
- B. Oculocardiac reflex
- C. Withdrawal reflex
- D. Patellar reflex
Explanation
Traction on the globe or extraocular muscles can stimulate the oculocardiac reflex, producing vagally mediated bradycardia. The other listed reflexes do not primarily cause this characteristic cardiovascular response during ocular surgery.
