In the fetus, the hyaloid canal contains a prolongation of the central artery of the retina, the hyaloid artery, which supplies blood to the developing lens. (wikipedia.org)
Once the lens is fully developed the hyaloid artery retracts and the hyaloid canal contains lymph. (wikipedia.org)
Sometimes part or all of this vessel will persist (persistent hyaloid artery if entire or hyaloid remnant if partial), occasionally it will still transport blood (patent hyaloid artery). (ashgi.org)

Posterior vitreous detachment (PVD) occurs when a dehiscence in the vitreous cortex allows fluid from a syneretic cavity to enter the potential subhyaloid space, causing the remaining hyaloid face to be stripped from the internal limiting membrane (ILM) of the retina (Fig 10-7). (aao.org)

Detachment of the posterior hyaloid from the pericentral retina exerts anterior traction on the foveola and localizes the dynamic vitreous traction associated with ocular rotations into the perifoveolar region. (aao.org)

Arteries2
Hyaloid arteries are not considered a hereditary problem, however their association with cataracts and the frequency with which they occurred among dogs which were part of the CEA study in the early 1990s is reason for concern. (ashgi.org)
Hyaloid arteries, though not recognized as a hereditary problem, may be one. (workingaussiesource.com)
Lens4
Hyaloid canal (Cloquet's canal and Stilling's canal) is a small transparent canal running through the vitreous body from the optic nerve disc (at the punctum caecum) to the lens. (wikipedia.org)
Contrary to initial belief, the hyaloid canal does not facilitate changes in the volume of the lens. (wikipedia.org)
Furthermore, lymph, being liquid, is incompressible, so even if the volume of the lens did change, the hyaloid canal could not compensate for it. (wikipedia.org)
Cloquet's canal, also known as the hyaloid canal or Stilling's canal, is a transparent canal that runs from the optic nerve disc to the lens traversing the vitreous body. (turningtooneanother.net)
Vasculature3
The hyaloid vasculature constitutes a transitory system nourishing the internal structures of the developing eye, but the mechanism of vascular regression and its cell biological characteristics are not fully understood. (elsevierpure.com)

Canal6
The hyaloid canal appears to have no function in the adult eye, though its remnant structure can be seen. (wikipedia.org)

Pupillary1
Adhesions may occur just between the pupillary margin and the anterior hyaloid surface. (medscape.com)
Vitrectomy1
The en face infrared (IR) image on the left demonstrates the "water mark" where the peripapillary subretinal fluid resolved following pars plana vitrectomy with release of traction. (uiowa.edu)
Vascular2
The galectin-3 + cells loosely aggregated with numerous erythrocytes in the lumen of hyaloid vessels in a manner reminiscent of vascular congestion. (elsevierpure.com)
Since macrophages may play central roles including blocking of the blood flow and the induction of apoptosis in the regression, galectin-3 + neutrophils may play a supportive role in the macrophage-mediated involution of the hyaloid vascular system. (elsevierpure.com)
Present1
The present study aimed to reveal the specificity of the hyaloid vessels by a systematic immunohistochemical approach for marker substances of myeloid cells and the extracellular matrix (ECM) in neonatal mice. (elsevierpure.com)
Retinal5
To describe visualization of the vitreous and the posterior hyaloid membrane using bromophenol blue during vitrectomy for macular hole and retinal detachment. (nih.gov)
Bromophenol blue appeared to be a very helpful and safe tool to visualize the posterior hyaloid membrane in macular hole surgery and assured its complete separation from the retinal surface. (nih.gov)
Hence, there is an extracellular diffusion pathway between hyaloid capillaries and retinal neurons, without interposition of glial cells. (rupress.org)
Vitreous hemorrhage can be due to leakage from persistent fetal (hyaloid) vessels or from retinal vessels, can follow trauma from intravitreal injections or retro-orbital bleeding procedures, or can be secondary to inflammation. (nih.gov)
