The peripheral retina terminates approximately 5 mm anterior to the equator of the eye at ____.

Explanation:
The peripheral retina ends at the ora serrata, which marks the boundary between the neural retina and the non-neural epithelium of the ciliary body. This edge sits about 5 mm anterior to the equator of the eye. Beyond the ora serrata, the tissue is part of the ciliary body (pars plana) rather than retina, which is why the ora serrata is the correct term for this boundary. The other structures are not that boundary: the pars plana is a portion of the ciliary body behind the ora serrata; the optic disc is the posterior location where the optic nerve exits the eye; and the macula is the central retina around the fovea.
