The vitreous base is located at which peripheral structure in the retina?

Explanation:
The strongest vitreoretinal attachment occurs at the peripheral edge of the retina where the retina ends and the ciliary body begins—the ora serrata. The vitreous base is that narrow zone surrounding this boundary where the vitreous cortex remains firmly attached to the retina. So the vitreous base sits at the ora serrata. The optic disc, macula, and retinal vessels are central retinal landmarks and do not define the site of this peripheral vitreoretinal adhesion.
