Pars plana
The pars plana is part of the uvea, choroidea, one of the three layers that comprise the eye. As a part of the ciliary body, it is about 4mm long, located near the point where the iris and sclera touch and is scalloped in appearance. The pars plana may not have a function in the post-fetal period, making this a good site of entry for ophthalmic surgery of the posterior segment (pars plana vitrectomy).
