Fig. 6. Vitreous structure in a 58-year-old woman. Fibers course anteroposteriorly in the central and peripheral vitreous. Posteriorly, fibers orient to the premacular region (top). Anteriorly, the fibers “splay out” to insert into the vitreous base (bottom right). (Sebag J: The Vitreous--Structure, Function and Pathobiology. New York, Springer-Verlag, 1989)
