Pars Plana Vitrectomy
Pars plana vitrectomy (PPV) is a common retinal procedure that is performed for the treatment of multiple conditions. Retinal detachments are often treated with pars plana vitrectomy. In addition, vitreous hemorrhages, macular pucker, macular hole, traction retinal detachment in diabetic retinopathy, and removal of vitreous opacities and floaters can all be treated effectively with vitrectomy surgery.
The Pars Plana Vitrectomy Procedure
In a vitrectomy, a retina specialist makes three small incisions—usually 1 mm or less—in the sclera, the white part of the eye. These are placed in a safe zone about 3–4 mm behind the edge of the cornea. Through these incisions, special cannulas are inserted, allowing saline-like fluid to enter the eye as the vitreous gel is removed with delicate, precise instruments.
Vitrectomy surgery is usually performed under a microscope, under very high magnification, using special instruments and lenses to visualize and illuminate the retina. In some cases, after the vitreous is removed, it is replaced with a temporary gas bubble (lasting 2-8 weeks) to keep the retina in place, allowing the retina to heal after surgery. In other cases, if there is severe retinal damage, the vitreous may be replaced with silicone oil that is usually left in place for several months before being removed.
Risks of Pars Plana Vitrectomy Surgery
Risks of surgery can include damage to the retina, including retinal tears or detachment, bleeding in the eye, intraocular infection, and cataract formation. Postoperative care may include a few weeks of special positioning, several weeks of topical eye drops, and several appointments in the first three months following surgery. For example, for macular hole repair, continuous face-down positioning for 24 hours daily may be required for 3-8 days. The position specifics and duration vary by surgeon and underlying diagnosis.
There will be activity restrictions at least for the first two weeks after the surgery, if not longer, based on what the underlying condition was that required the vitrectomy. Specific postoperative instructions unique to each case will be given to the patient and their family at the end of surgery.
