Visual hallucinations on eye closure after cardiovascular surgery.

Area of Science:

• Neurology
• Ophthalmology
• Cardiovascular Surgery

Background:

• Visual hallucinations upon eye closure are an uncommon phenomenon.
• The precise pathophysiological mechanisms underlying these hallucinations remain poorly understood and debated.
• This report focuses on a specific neurological event occurring post-cardiac surgery.

Observation:

• A patient experienced visual hallucinations specifically when closing their eyes after undergoing carotid endarterectomy and coronary artery bypass graft surgery.
• The clinical presentation was meticulously documented, including the timing and characteristics of the hallucinations.
• No other neurological deficits were reported concurrently.

Findings:

• The occurrence of visual hallucinations post-cardiac surgery suggests a potential neurological complication.
• The hypothesis of temporal lobe epilepsy (TLE) is proposed as a possible explanation for the observed visual phenomena.
• Further investigation is warranted to confirm the etiology and rule out other potential causes.

Implications:

• This case highlights a rare but significant potential adverse event following carotid endarterectomy and coronary artery bypass graft surgery.
• Understanding the link between cardiovascular procedures and neurological events like visual hallucinations can improve patient monitoring and care.
• The discussion of temporal lobe epilepsy as a potential cause may guide future diagnostic and therapeutic strategies for similar cases.
