Overview
Pars plana vitrectomy (PPV) is a commonly employed technique in vitreoretinal surgery that enables access to the posterior segment for treating conditions such as retinal detachments, vitreous hemorrhage, endophthalmitis, and macular holes in a controlled, closed system. The procedure derives its name from the fact that vitreous is removed (i.e. vitreous + ectomy = removal of vitreous) and the instruments are introduced into the eye through the pars plana.
Indications
Removal of vitreous opacities, relief of vitreoretinal traction, restoration of the natural anatomical connection of the retina and retinal pigment epithelium (RPE), and access to the subretinal region are all reasons for pars plana vitrectomy.
