XAO:0004155 TAO:0005045 In humans, Usually fully regressed before birth, its purpose is to supply nutrient to the developing lens in the growing fetus. During the tenth week of development the lens grows independent of a blood supply and the hyaloid artery usually regresses. Its proximal portion remains as the central artery of the retina. Regression of the hyaloid artery leaves a clear central zone through the vitreous called the hyaloid canal or Cloquet's canal. Occasionally the artery may not fully regress, resulting in the condition persistent hyaloid artery. More commonly, small remnants of the artery may remain. Free remnants can sometimes be seen as 'floaters'. An anterior remnant of the hyaloid artery can be seen in some people as Mittendorf's dot, a small pinpoint-like scar on the posterior surface of the lens. A posterior remnant may be seen where the artery left the optic disc, and is known as Bergmeister's papilla EMAPA:19242 optic stalk brain blood vessel optic fissure hyaloid vessel hyaloid cavity hyaloid canal
