The cellular components of the vitreous body have been subject to some controversy. It has been established that in the course of embryonic development the vitreous body contains numerous cells, but their nature and origin are not well known. The adult vitreous body is considered to be primarily cell-free. However, in the cortical layer, the so-called "hyaloid area," different types of cells have been described repeatedly.

One of the first reports on the cells in the adult vitreous body is that of Henle (1841), who mentions "cytoblasts" in the vicinity of the zonula fibers. Donders (1847) studied the posterior surface of the vitreous body and described "corpuscles," which Doncan (1854) later characterized as cells. Doncan gives a detailed description of these cells in the cortical layer of the human vitreous body as well as in the vitreous body of cattle, dogs, cats, rabbits, and several kinds of fish.
