Abstract

The study of the innervation of the pupil dilation has an almost two-century history. Hundreds of works are devoted to the development of this issue, but to this day you can still encounter something obscure, contradictory. Our task is not to provide a complete literary review of the works related to this, since such are already available in several works, both Russian and foreign researchers, we will limit ourselves only to the presentation of the most important studies and will not at all touch upon the scholarship of the intimate aspect of the study expansion.
