Neuro pupillary response
- 0Dec 10, '12 by danmarin_99First a little information about the patient: the patient is currently intubated receiving both propofol and Ativan. Among other medications; Dilantin and morphine. This patient is also a recreational drug user at home of both cocaine and Xanax. My question is: in assessing their neurological status, I was checking the response to light and the patient's pupils contract AND relax rhythmically several times until the light is taken away. They do not fix at a particular mm. I figure it is a response to the drugs and I received in report that this is a known thing, but I am curious if anyone else has seen this.

From what our doc's tell us, its usually a normal finding, they never seem to be concerned when I find this in one of my kiddos.

Hippus is visible, rhythmic, but irregular pupillary oscillations that are deliberate in time. It comprises 2 mm or more excursions and has no localizing significance.
