prof. Dr. Ümit İNAN, Pars plana vitrectomy (PPV) is a technique used in vitreoretinal surgery to treat conditions such as retinal detachments, vitreous hemorrhage, endophthalmitis and macular holes in a controlled, closed system. The procedure takes its name from the vitreous removal from the eye (ie vitreus + ectomy = vitreous removal) and the introduction of instruments into the eye through the pars plana.
