Pars plana vitrectomy is a general term for a group of operations accomplished in the deeper part of the eye, all of which involve removing some or all of ...
The adhesion in of itself is not dangerous, but the resulting pathological vitreomacular traction (VMT) can cause severe ocular damage. The current standard of care for treating these adhesions is pars plana vitrectomy (PPV), which involves surgically removing the vitreous from the eye.

The risk of retinal detachment is the greatest in the first 6 weeks following a vitreous detachment, but can occur over 3 months after the event.. The risk of retinal tears and detachment associated with vitreous detachment is higher in patients with myopic retinal degeneration, lattice degeneration, and a familial or personal history of previous retinal tears/detachment.
Vitrectomy is the common way to treat a macular hole. It is done by placing a gas bubble in the vitreous of the eye which helps flatten the macular hole and holds it in place as the eye heals. The gas bubble slowly shrinks on its own. [6] Treatment is also done using ocriplasmin. [7]
