This document discusses pupillary examination and various aspects of pupillary reflexes. It begins by describing the pathway of the pupillary light reflex from the retina through the brain. It then discusses the efferent pathway from the Edinger-Westphal nucleus to the iris sphincter muscle. The document also covers the near reflex pathway and differences between the light and near reflexes. It provides tips for examining pupillary reflexes, potential causes of anisocoria, and tests such as color vision testing and confrontation visual field testing.
