Hyaloid canal is a small transparent canal running through the vitreous body from the optical nerve disc to the lens; it contains a prolongation of the central artery of the retina, the hyaloid artery.The function of the canal is to provide an adjustable reservoir of mobile liquid which may be easily and rapidly displaced backwards in positive accommodation, forwards in negative accommodation.

Good answer, but this is somewhat incorrect. The optic nerve is the continuation of the retina exiting out of the posterior part of the eye. The retina is the inner most layer of the eye covering the interior surface. The Canal inside of the eye is called the Hyaloid Canal, which contained the Hyaloid Artery during fetal development. In the later stages of fetal development, the Hyaloid Artery, which exists to provide nutrients to the lens during development, regresses and therefore leaves behind the Hyaloid Canal. Its main purpose is serving as a fluid passageway. Hope that wasn't too much detail. Good original answer though. You were close. The Hyaloid Canal extends from the lens to the optic disc (head of the optic nerve).
