What does pars plana vitrectomy mean?
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.
When is pars plana vitrectomy used?
Vitrectomy surgery (or pars plana vitrectomy) is a common surgical procedure that is used for a wide number of conditions of the retina. These include: diabetic retinopathy, retinal detachment, macular pucker, macular hole and vitreous hemorrhage to name a few.
How much does a pars plana vitrectomy cost?
The analysis showed that when pars plana vitrectomy was the primary procedure, the overall imputed cost ranged from $5,802 to $7931. The cost per line ranged from $2,368 to $3,237. The cost per line-year saved was $163 to $233. The cost per QALY was $5,444 to $7,442.
What happens after pars plana vitrectomy?
After the surgery, your eye may be swollen, red, or tender for several weeks. You might have some pain in your eye and your vision may be blurry for a few days after the surgery. You will need 2 to 4 weeks to recover before you can do your normal activities again.

What are the risks of vitrectomy surgery?
What are the risks of vitrectomy?
- Excess bleeding.
- High pressure in the eye.
- New retinal detachment caused by the surgery.
- Lens damage.
- Increased rate of cataract formation.
- Problems with eye movement after surgery.
- Change in refractive error.
Can I sleep on my side after vitrectomy surgery?
It is recommended to sleep on either side or even your front, but not sleep on your back as that would make the bubble move away from the macular hole.
What can you not do after a vitrectomy?
In general, activities like driving, reading, and exercise will need to be avoided for a few days after the procedure.

The procedure derives its name from the fact that vitreous is removed (i.e.
What was the first closed system vitrectomy?
Two years later, Robert Machemer created the first closed system vitrectomy setup – which enabled intraocular pressure control – using 17-gauge instruments with a pars plana approach, the beginning of what became known as pars plana vitrectomy.
How are soft lenses removed from pars plana?
For pars plana lensectomy, soft lenses can be removed using the vitrectomy cutter, but denser lenses may require use of the fragmatome. The fragmatome operates similarly to a phacoemulsification probe although use of the conventional fragmatome requires enlarging sclerotomies, often using an MVR blade.
What happens when you have a 20 gauge vitrectomy?
In addition, patients with 20-gauge, sutured wounds may have a decreased rate of endophthalmitis compared to patients undergoing smaller-gauge vitrectomy surgery, a finding possibly related to hypotony and wound leakage more commonly seen in sutureless surgery.
