Which finding extends the peripheral retina onto the pars plana?

Explanation:
Dentate processes are tooth‑like extensions of the peripheral retina that reach onto the pars plana. They create a serrated border at the ora serrata as the retina ends and the ciliary body begins. Oral bays, on the other hand, are the gaps between these dentate projections and do not themselves represent retinal tissue extending onto the pars plana. So the feature that actually extends the retina onto the pars plana is the dentate processes.
