INTRAOCULAR TENSION VARIATIONS WITH ELECTROCONVULSIVE THERAPY

Area of Science:

• Ophthalmology
• Neuroscience
• Psychiatry

Background:

• Electroconvulsive therapy (ECT) is a medical procedure that involves a brief electrical stimulation of the brain while the patient is under anesthesia.
• Variations in physiological parameters, including intraocular pressure (IOP), are potential concerns during ECT.
• Understanding these variations is crucial for patient safety and management.

Purpose of the Study:

• To investigate and compare intraocular tension variations during modified ECT and direct ECT.
• To assess the impact of succinylcholine on intraocular pressure changes during ECT.

Main Methods:

• The study involved 40 psychiatric patients undergoing ECT.
• Intraocular tension was monitored following both modified and direct ECT procedures.
• Succinylcholine's effect on intraocular pressure was specifically evaluated.

Main Results:

• A significant increase in intraocular pressure was observed in all patients following both ECT methods.
• The rise in intraocular pressure was more marked and sustained when succinylcholine was administered.
• Direct ECT showed a more pronounced effect on IOP compared to modified ECT.

Conclusions:

• Both modified and direct ECT lead to significant elevations in intraocular pressure.
• Succinylcholine administration exacerbates and prolongs the increase in intraocular pressure during ECT.
• Anesthesiologists and ophthalmologists should be aware of these IOP changes for effective patient management during ECT.
