A well-appearing infant with a sudden anisocoria

Area of Science:

• Pediatric Neurology
• Ophthalmology

Background:

• Sudden unilateral mydriasis in infants can be a sign of serious underlying pathology.
• A history of head trauma, even minor, warrants careful neurological assessment in children.

Purpose of the Study:

• To report a case of unilateral mydriasis in a pediatric patient following minor head trauma.
• To emphasize the diagnostic considerations and management of anisocoria in infants.

Main Methods:

• Clinical case presentation.
• Detailed neurological and ophthalmological examination.
• Review of medical history, including recent trauma.

Main Results:

• A 10-month-old boy developed left unilateral mydriasis.
• The child had a history of minor head trauma two days prior to presentation.
• Neurological and physical examinations were otherwise normal.

Conclusions:

• Unilateral mydriasis in a pediatric patient, even after minor head trauma, requires thorough investigation.
• Prompt medical evaluation is crucial to rule out significant intracranial pathology.
