Hyaloid canal

Canalis hyaloideus

  • Eponym: Canal of Cloquet; Stilling’s canal

Definition

Muhammad A. Javaid

The hyaloid canal (also called Cloquets canal) is a narrow, transparent channel that extends through the centre of the vitreous body from the optic disc posteriorly to the posterior surface of the lens anteriorly; close to the retrozonular space and the hyaloid fossa.

Embryological correlate

It represents the remnant of the embryonic pathway of the hyaloid artery, which supplies the developing lens during fetal life. In the adult eye, the hyaloid artery normally regresses before birth, leaving the hyaloid canal as a vestigial structure without significant contents.
