What forms the secondary vitreous postnatally?

Explanation:
After birth, the vitreous gel is formed in part by new components produced by the surrounding ocular mesenchyme and glial cells. This secondary formation means the extracellular matrix—collagen, hyaluronic acid, and related proteins—continues to be synthesized and organized as the vitreous matures, so its final gel state develops postnatally. The hyaloid vessels and any regressive remnants belong to the primary vitreous, which forms earlier and largely regresses, sometimes leaving small remnants. The retinal pigment epithelium and optic nerve fibers are retinal structures and do not contribute to making the vitreous.
