Pars plana vitrectomy (PPV) is the most commonly performed surgical procedure for a retina surgeon.It is a invasive procedure that involves removal of a part or of the entire vitreous from the eye. Pars plana vitrectomy was developed by Robert Machemer in 1970. Common indications include retinal detachments, retained lens fragments after cataract surgery, vitreous haemorrhage, endophthalmitis, epiretinal membrane, macular hole, vitreomacular traction, intraocular foreign bodies.
In the last years due to the development of new instruments and techniques the operators also practice vitrectomy for floaters.(FOV)
