An Attempt to Understand Flicker Vertigo: Changes in Pupil Size and Choroidal Blood Flow under Flickering Conditions

摘要

Light flickering at a rate of 4- 20 cycles per second can produce unpleasant reactions such as nausea and vertigo. In this paper, the possibility of achieving an objective evaluation/prediction of the physiological effects induced by flicker is investigated using a new imaging method based on the pupil size determination. This method is also compared with the blood flow analysis in the choroid.
