The blepharocardiac reflex.

Archives of Ophthalmology (Chicago, Ill. : 1960)

|August 1, 1978

Summary

This summary is machine-generated.

The oculocardiac reflex, a triad of bradycardia, nausea, and faintness, can be triggered by eyelid muscle stretching. This study documents this reflex in ptosis and entropion surgeries, recommending monitoring and atropine for management.

Area of Science:

Ophthalmology
Cardiology
Neurology

Background:

The oculocardiac reflex is a well-documented phenomenon involving bradycardia, nausea, and syncope.
It is typically elicited by direct ocular manipulation or pressure, involving the trigeminal and vagus nerves.

Observation:

This study observed the oculocardiac reflex during eyelid surgeries, specifically ptosis and entropion repair.
The reflex was noted in patients undergoing traction on the levator aponeurosis and lower eyelid retractors.

Findings:

This research provides the first documentation of the oculocardiac reflex being elicited by stretching eyelid muscles.
The reflex occurred in a significant proportion of patients undergoing specific eyelid surgeries.

Implications:

Early recognition through electrocardiogram monitoring and prompt treatment with atropine are crucial.
Careful surgical technique and preoperative atropine may reduce the incidence of this reflex during ophthalmic procedures.
