| Description |
The normal pupillary light reflex is initiated following exposure to light. After a brief latency, both the right (solid line) and left (broken line) pupil constrict, then undergo a small amount of redilation (escape), followed by oscillations (hippus) if the light is sustained. Hippus is not a pathologic sign. (Corbett JJ, Thompson HS: Pupillary function and dysfunction. In Asbury AK, McKhann GM, McDonald WI [eds.]: Diseases of the Nervous System.
