The Mittendorf dot

  The Mittendorf dot, determined by William Frederick Mitttendorf, is a congenital vascular abnormality of eye which takes place because of an involutional fault of the anterior terminus of anterior hyaloid artery. It manifests as a focal opacity in the infero-nasal element of the posterior lens capsular surface. It is a scientific version of persistent fetal vasculature (PFV), a spectrum of situations that rise up whilst fetal hyaloid vasculature fails to involute. The Mittendorf dot is concept to be connected to the posterior lens capsular surface itself; current research suggests the opportunity of a retrolental presence of the dot inside the anterior vitreous. A lone Mittendorf dot is a exceptionally benign clinical finding and no inflicting any visual impairment
