Pars Plana Vitrectomy Eye Surgery Vitrectomy is when the eye surgeon removes the vitreous from the inside of the eye. Pars plana vitrectomy is a general term for a group of operations on the deeper part of the eye, all of which involve the removal of some or all of the vitreous – the eye’s clear internal jelly. Pars plana vitrectomy eye surgery is sometimes done to remove eye floaters or vitreous hemorrhage inside the eyeball. In a vitrectomy, the surgeon “vacuums” out the normally clear, jelly-like fluid that fills the inside of the eye, the vitreous humor, with a surgical instrument called a vitrector. The vitrectomy procedure

- A vitrectomy performed for diseases of the posterior segment is called a posterior or pars plana vitrectomy. This kind of vitrectomy is performed by a retina specialist. Anterior Vitrectomy: In rare cases, the vitreous gel comes through the pupil into the anterior (front) chamber of the eye. This can happen:

- Vitrectomy eye surgery is done for conditions like retinal detachment, diabetic retinopathy and for complications of cataract surgery like infection or retained lens matter. This involves removing the vitreous gel in your eye with tiny keyhole incisions.

Vitrectomy & complications..vitreous Data on vitrectomy. 1  Patients with proliferative retinopathy have a 33% risk of a vitreous haemorrhage at some time. 2  About 25% of these haemorrhages are recurrent or severe and need a vitrectomy. 3  After vitrectomy about 20% bleed needing a washout.  After vitrectomy, 33% have vision better than 6/18. 3% develop rubeotic glaucoma.

Posterior Vitreous Detachment Synonyms: vitreous detachment, vitreous separation. Posterior vitreous detachment (PVD) is the separation of the posterior hyaloid face of the vitreous body from the neurosensory retina. The importance of PVD is that it is common but its symptoms and signs may mimic those of a retinal detachment. PVD is the most common cause of flashes and floaters.

Overview The light continues through the vitreous humor, the clear gel that makes up about 80% of the eye s volume, and then, ideally, back to a clear focus on the retina, behind the vitreous.

Included are descriptions, functions, and problems of the major structures of the human eye: conjunctiva, cornea, iris, lens, macula, retina, optic nerve, vitreous, and extraocular muscles.

- It is difficult to predict how much the vision will improve after surgery. Vitrectomy surgery is aimed at restoring the normal anatomy of the eye either by removing blood or debris from the eye, removing scar tissue from the eye or repairing a detached retina.

Pars Plana Vitrectomy Modern pars plana vitrectomy was developed by Robert Machemer in 1970.Machemer created the vitreous infusion suction cutter (VISC), which was the first closed-system vitrectomy device with infusion and aspiration to control intraocular pressure during the surgical procedure.

- Posterior vitreous detachment, or PVD for short, is a degenerative change in the vitreous humor of the eye.It is very common and will occur in virtually everybody as age catches up. Most of the time, it occurs without causing any acute or long-term visual problems.osterior vitreous detachment, or PVD for short, is a degenerative change in the vitreous humor of the eye.

- However, vitreous detachment may make you more susceptible to retinal detachment and macular hole formation, which are serious conditions that are known to cause visual loss. Healthy vitreous comprises 80% of the eyeball volume. Vitreous is extraordinarily clear and changes consistency throughout life. The melting and shrinking of the vitreous that causes vitreous detachment is a part of normal aging and generally begins around the age of 50.

Posterior Vitreous Detachment When this happens, the vitreous shrinks and pulls away from the retina at the back wall of the eye. This separation of vitreous from retina is called posterior vitreous detachment. (Image adapted from the internet).

Vitreous detachment Listen. Most of the eye’s interior is filled with vitreous. There are millions of fine fibers intertwined within the vitreous that are attached to the surface of the retina. As we age, the vitreous slowly shrinks, and these fine fibers pull on the retinal surface. Usually the fibers break, allowing the vitreous to separate and shrink from the retina. This is a vitreous detachment.

Vitrectomy Procedure With the vitrectomy procedure it is possible to remove all the vitreous of the eye and any floaters it contains. The procedure is usually quite imprecise for floaters so instead of removing just the floaters, they attempt to remove most of the vitreous in hopes on removing the floaters in the process.

Eye Anatomy: How Do Our Eyes Work? Vitreous humor makes up approximately 80 percent of the volume of the eyeball. It is a gel-like substance in the back part of the eye that provides the shape of the eyeball. The vitreous humor is located between the lens and the retina, in an area called the vitreous cavity.

- The main part of the eye is the eyeball (also known as the globe), which is mostly filled with a jelly-like material called vitreous humor. The eyeball has 3 main layers: the sclera, the uvea, and the retina.

- Many retinal diseases require laser photocoagulation treatment as a part of vitrectomy surgery. The laser is often used to treat vitreous hemorrhage (suspended blood in the vitreous gel) or abnormal blood vessels in diabetic retinopathy as well as seal tears in the retina that can lead to retinal detachment.

Epiretinal membrane Healthgrades Editorial Staff. Posterior vitreous detachment, sometime simply called vitreous detachment, occurs when the vitreous, a gel-like substance attached to the retina in the back of the eye, shrinks and pulls away from the retina. By itself, vitreous detachment does not seriously affect your vision and usually does not require any treatment.

Macular Hole Surgery Macular Hole Surgery. During macular hole surgery (vitrectomy), a bubble containing a mixture of air and gas is placed in the eye -- this helps the macular hole to heal. The bubble is gradually reabsorbed by the eye, thus sealing the hole. Following this type of surgery, patients must remain in a face-down position for a period of time. Although some macular holes can seal themselves and require no treatment, surgery is necessary in many cases to help improve vision. The surgery used for macular hole treatment is called a vitrectomy.

The main purpose of the lens is to focus light by changing shape. The ciliary body is a muscle group attached to the lens that help the lens change its shape to better focus light on the retina.
