    Unequal pupil size after anesthesia can indicate serious brain issues. This study reveals an unusual cause: phenylephrine nasal spray accidentally entering the eye, causing anisocoria.

    Area of Science:

    • Ophthalmology
    • Anesthesiology
    • Neuroscience

    Background:

    • Anisocoria, or unequal pupil size, post-anesthesia can be a concerning sign of intracranial pathology.
    • Prompt diagnosis and management are crucial for patients presenting with this symptom.

    Observation:

    • A case of anisocoria following anesthesia is presented.
    • The cause was identified as accidental ocular exposure to phenylephrine nasal vasoconstrictor solution.

    Findings:

    • Phenylephrine, a sympathomimetic agent, can induce mydriasis (pupil dilation).
    • Accidental eye contamination with nasal phenylephrine spray can mimic serious neurological conditions.

    Implications:

    • Highlights the importance of considering topical ocular medications as a cause of anisocoria in the perioperative period.
