Definition
Surgical procedure to remove the vitreous or part thereof by accessing vitreous cave via pars plana.
Epidemiology
Formerly related to a large variety of serious complications, vitrectomy – especially small-gauge pars plana vitrectomy – has become a widely used technique for a large number of pathologies. To date approximately 200,000 vitrectomies are performed in the USA per year.
