Presentation
We present the case of a woman with epileptic seizures consisting of sustained fluctuation of perception of brightness. [pubmed.ncbi.nlm.nih.gov]
They are present in everybody and increase slightly at high luminances. The frequency of these oscillations is about 1.4 Hz. [medical-dictionary.thefreedictionary.com]
Vegetative responses are commonly present during and following epileptic seizures. [onlinelibrary.wiley.com]
Results: Pupillary hippus with a distinct dominant frequency was present in all measures at baseline (mean: 0.62 Hz, SD: 0.213 Hz), and that frequency did not change in any group (P = 0.971). [ncbi.nlm.nih.gov]

Treatment
Each subject received one drop to the randomly determined treatment eye, while the other eye served as control. Bilateral measures of pupil size and dynamics were made over 2.6 seconds using an infrared eye-tracker sampling at 500 Hz. [ncbi.nlm.nih.gov]

Etiology
The most common diagnosis was nystagmus of unclear etiology. Pupil size of all patients was recorded in the same room with the same lighting using infrared video-oculography at 240 Hz. [n.neurology.org]
