1. Review the anatomy of the oculosympathetic pathway. 2. Learn to localize lesions based on clinical findings and thus insure that the appropriate areas of interest are visualized on cross sectional imaging. 3. Common causes of this syndrome will be discussed.
Horner’s Syndrome (oculosympathetic dysfunction) occurs when there is interruption of the sympathetic innervation of the eye. The clinical symptoms may cause little if any functional impairment in most patients. However, a thorough clinical evaluation of patients with this condition is required, because the etiologies of this condition include both benign and malignant disease processes.
Cross-sectional imaging plays a major role in the identification of a lesion along this complex neural pathway. Knowledge of the anatomy, clinical symptoms and the pupillary response to various pharmacological agents is required to optimize the radiological evaluation.
