Population-Based Incidence of Horner Syndrome

In this interview from AAO 2020 Virtual, Dr. John Chen discusses the population-based incidence and manifestations of Horner syndrome. The dataset included 78 adults diagnosed with Horner syndrome in Olmsted County from 2000 to 2018. The age- and sex-adjusted incidence was 4.2 per 100,000 per year with no differences based on sex but an increasing incidence with age. The most common etiology was idiopathic (26%), followed by internal carotid artery (ICA) dissection (19%) and stroke (15%). The findings indicate that isolated cases with pain or facial paresthesia should undergo imaging to assess for an underlying ICA dissection.
