Tunica Vasculosa Lentis
Although they are commonly observed, remnants of the tunica vasculosa lentis and hyaloid artery are not visually significant. Mittendorf dot, an anterior remnant, is a small, dense, and white round plaque attached to the posterior lens capsule nasally and inferiorly to its posterior pole. A prepapillary remnant known as Bergmeister papilla is a fibroglial tuft of tissue extending into the vitreous for a short distance at the margin of the optic nerve head. The entire hyaloid artery may persist from optic nerve head to lens as multilayered fenestrated sheaths forming the Cloquet canal.
