A Patient-Friendly Guide to Vitrectomy (Pars Plana Vitrectomy) for Retinal Disease

Vitrectomy, also called pars plana vitrectomy, is a common retinal surgery performed by retina specialists to treat diseases affecting the retina and vitreous (the clear gel inside the eye). During surgery, the vitreous gel is carefully removed to allow the surgeon better access to the retina. This helps repair retinal problems, remove scar tissue or blood, treat retinal detachments, close macular holes, remove retained lens fragments, or improve vision in certain conditions involving the vitreous or retina.

The retina is the thin layer of nerve tissue lining the back of the eye that captures light and sends signals to the brain so we can see. The vitreous is a gel-like material that fills most of the eye and is attached to the retina. In some retinal diseases, the vitreous may pull on the retina, become cloudy with blood, or contain scar tissue that affects vision. Vitrectomy allows your retina specialist to remove this gel and safely treat the underlying problem.

Vitrectomy may be recommended for conditions such as retinal detachment, vitreous hemorrhage (bleeding inside the eye), macular holes, epiretinal membranes (scar tissue), retained lens fragments after cataract surgery, eye infections, severe diabetic retinopathy, or visually significant floaters in selected patients. Once the vitreous is removed, the surgeon may use laser treatment, peel scar tissue, remove blood, or place a gas bubble or silicone oil inside the eye to support healing.

The surgery is usually performed in an operating room under local anesthesia with sedation or sometimes general anesthesia. Small instruments are placed through tiny openings in the white part of the eye. Most patients go home the same day. Depending on the reason for surgery, the surgeon may leave saline, a gas bubble, or silicone oil inside the eye at the end of the procedure to help support the retina while healing occurs. Vitrectomy often involves additional procedures tailored to your eye condition. Vitrectomy removes the vitreous gel to improve access to the retina and support repair of retinal disease. citeturn0search0turn0search2

After surgery, vision is often blurry at first and gradually improves over time. If a gas bubble is placed in the eye, vision may appear very blurry or look like a moving line or “water level” until the bubble slowly dissolves. Some patients may need special head positioning, such as face-down positioning, depending on the retinal condition and surgery performed. Airplane travel and high-altitude travel must be avoided while a gas bubble remains in the eye because changes in pressure can dangerously raise eye pressure. citeturn0search7turn0search0

Recovery time depends on the underlying condition and the complexity of surgery. Mild soreness, redness, tearing, light sensitivity, or irritation are common for several days after surgery. Eye drops are usually prescribed to reduce inflammation and lower the risk of infection. Many patients gradually resume normal activities, although heavy lifting or strenuous activity may be temporarily restricted. citeturn0search7turn0search0

Although vitrectomy is very successful for many retinal diseases, risks and complications can occur. These may include cataract progression, retinal tear or retinal detachment, infection, bleeding, elevated eye pressure, swelling, or the need for additional surgery. Your retina specialist will discuss the risks and expected outcomes for your specific eye condition. citeturn0search3turn0search4

Prompt follow-up appointments are very important after surgery. Contact your retina specialist immediately if you experience worsening pain, increasing redness, severe light sensitivity, sudden vision loss, worsening flashes or floaters, or a curtain-like shadow in your vision.
