Diagnosis of pupillary disorders

Abstract

Pupillary testing serves two purposes, first, to find disorders of pupillary function itself, and second, to detect disorders of the afferent visual system and the autonomic innervation of the eye. A systematic approach will help significantly with interpretation of the findings. The examination should be done in a logical order, since the pupillary system responds in a logically predictable way. Tests that yield no useful information can only create confusion.
