Wrigh page 30Some named structures around vitreous:Weigers ligament capsulohyaloid ligament or eggers line : attachment of vitreous to posterior surface of lensBergers space: centre of hyalocapsoid ligament or weigers ligamentCloquets canal: During the tenth week of development in humans time varies depending on species, 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 humor, called the hyaloid canal or Cloquets canalArea of martergiani: posterior area of cloquets canal which is seen as weiss ring.Mittendorfs dot: 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.Bergmeisters papilla: A posterior remnant may be seen where the artery left the optic disc, and is known as Bergmeisters papilla
