Pupil cycle time: a simple way of measuring an autonomic reflex. [PDF]

open access: yesJournal of Neurology, Neurosurgery & Psychiatry, 1986
Persistent regular oscillations of the pupil of the eye can be induced using a slit-lamp. The period of these oscillations, pupil cycle time (PCT), is simple to measure with a hand-held stop-watch. Evidence from pharmacological testing suggests that PCT is a sensitive measure of dysfunction of the parasympathetic efferent limb of the pupillary light ...
