Acute Pre-ganglionic Horner Syndrome Positive to Apraclonidine Test

Abstract

Horner syndrome (HS) is characterized by pupillary miosis, upper eyelid ptosis, apparent enophthalmos and facial anhidrosis. It has been reported as a rare complication of thoracic surgery. We describe a 12-year-old girl who presented with a pre-ganglionic HS one day after cardio-thoracic surgery for post-ductal coarctation of the aorta. Apraclonidine test was positive on the twelfth day following the onset of HS.
