The Pupillary Light Reflex in Idiopathic Intracranial Hypertension.

Investigative ophthalmology & visual science, 2016
To evaluate the effects of idiopathic intracranial hypertension (IIH) on rod-, cone-, and melanopsin-mediated pupillary light reflexes (PLRs).Pupillary light reflexes elicited by full-field, brief-flash stimuli were recorded in 13 IIH patients and 13 normal controls.
