Pars plana vitrectomy (PPV) is a surgical technique originally introduced by Robert Machemer. The pars plana approach to the vitreous cavity allows access to the posterior segment to treat many vitreoretinal diseases. This procedure requires a great deal of technical skill and knowledge to ensure good outcomes. A successful vitrectomy can restore vision and improve the quality of life in patients suffering from many vitreoretinal diseases. However, the procedure can also be associated with complications. Although the chances are low when performed correctly, these complications can cause severe patient morbidity and blindness. Therefore, it is essential that clinicians have thorough knowledge regarding the topic, understand the procedure, when to use it, how to perform it, and post-operative management.
