See below: Pars plana vitrectomy (ppv) is performed using small instruments that pass through the white of the eye (scleral). The vitrector cuts up and aspirates the vitreous jelly. This allows access by the surgeon to the underlying retina for therapeutic surgical maneuvers like membrane peeling, laser application, and/or gas/oil tamponade depending on the diagnosis needing surgery.
