The sympathetic innervation of the eyes and face: A clinicoanatomic review

Most of the details regarding the course of the sympathetic fibers to human ocular structures are based on anatomical and physiological studies in lower animals. While studying a clinical problem involving pericarotid sympathetic fibers, it became obvious that these animal observations cannot adequately explain the findings in human diseases affecting these pathways. An attempt was made, therefore, to clarify this situation.
