The tunica vasculosa lentis is an extensive capillary network, spreading over the posterior and lateral surfaces of the lens of the eye.
It disappears normally shortly after birth, through apoptosis.
[1] The structure was not studied properly and in detail until the 1960s, when new technologies developed to allow the preservation of the networks in fetuses.
[2] The scanning electron microscope finally enabled researchers to see the network even in very small laboratory animals such as the mouse embryo.
