Latanaprost Treatment of the Heterochromia in a Patient with Acquired Horner Syndrome

Abstract

Horner syndrome results from either congenital or acquired causes of sympathetic denervation. Heterochromia, a clinical feature of congenital Horner syndrome, is quite rare in acquired Horner syndrome, especially after the age of two. There were only a few cases reported previously. We reported a 24-year-old man who was diagnosed up on pharmacological tests and clinical findings as acquired Horner syndrome with heterochromia. The main complaint of the patient was hypochromia on the affected side, which was obviously improved after 19 months of latanoprost treatment.
