Background Proliferative vitreoretinopathy (PVR) is the most common cause of failure in retinal detachment surgery. It can occur in untreated eyes or occur after pneumatic retinopexy, cryotherapy, laser retinopexy, scleral buckling, or vitrectomy.

- 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.itreous detachment by itself is not a serious medical condition and is not a serious threat to your vision. Seek prompt medical care if you have mild symptoms that recur or are persistent. Vitreous detachment increases the risk of retinal detachment and macular hole.

Bleeding in the White of the Eye (Subconjunctival Hemorrhage) If a small blood vessel breaks in the white part of your eye, the blood makes part of the white of your eye bright red.

PROLIFERATIVE VITREORETINOPATHY (PVR) Proliferative Vitreoretinopathy (PVR) occurs when a scar forms under or on the retina after retinal detachment, preventing the retina from healing and falling back into place.isk factors for Proliferative vitreoretinopathy PVR include large retina tears or retinal detachment that is not treated early. Bleeding within the eye, increased inflammation from trauma and previous retinal detachment operations also increase the risk.

Proliferative Vitreoretinopathy PVR is strictly defined as a complication of rhegmatogenous retinal detachment that is characterized by the formation of membranes on both surfaces of the detached retina and on the posterior surface of the detached vitreous gel.t is manifest by the formation of fibrocellular membranes on the retinal and posterior hyaloid surfaces. Most cells in PVR membranes originate from adjacent retina and the displaced cells synthesize much of the membrane matrix. The membranes have some features in common with healing wounds.

Overview A subconjunctival hemorrhage (sub-kun-JUNK-tih-vul HEM-uh-ruj) occurs when a tiny blood vessel breaks just underneath the clear surface of your eye (conjunctiva). You may not realize you have a subconjunctival hemorrhage until you look in the mirror and find the white part of your eye is bright red.

Retinal vessel occlusion A retinal vessel occlusion is a blockage in the blood vessel of your eye that can result in sight loss. There are two types of retinal blood vessels, arteries and veins. Either of these can become blocked and each of them can affect the eye in different ways. The visual loss caused by retinal vein and artery occlusions is painless. It is usual for only one eye to be involved at a time, but occasionally both eyes may be affected at the same time.

INTERNATIONAL GUIDE DOG FEDERATION Flashes and Floaters (Posterior Vitreous Detachment). The space between the crystalline lens and the retina is filled with a clear, gel-like substance called vitreous. In a newborn, the vitreous has an egg-white consistency and is firmly attached to the retina.With age, the vitreous thins and may separate from the back of the eye. This is called posterior vitreous detachment (PVD), a very common, usually harmless condition.As the vitreous pulls free from the retina, light flashes or floaters often accompany it.Floaters are caused by tiny bits of vitreous gel or cells that cast shadows on the retina. Flashes occur when the vitreous tugs on the sensitive retina tissue. There are other more serious causes of flashes and floaters, however.n a newborn, the vitreous has an egg-white consistency and is firmly attached to the retina. With age, the vitreous thins and may separate from the back of the eye. This is called posterior vitreous detachment (PVD), a very common, usually harmless condition.

Causes, Symptoms of Broken Blood Vessel in the Eye and Treatment A broken blood vessel in the the eye is usually nothing more that the breakage of the many tiny blood vessels that are found within the eye. A broken blood vessel in the eye is known as a subconjunctival hemorrhage.The conjunctiva is the clear surface of your eye, and a hemorrhage is the breaking of the blood vessels. This condition is most often harmless and under normal circumstances will clear up in one to three weeks.f you are experiencing any pain with the broken blood vessel in your eye, you may want to take a trip to the ophthalmologist, other wise known as the eye doctor. If your symptoms worsen or do not improve within a few days, this may be a sign of a more serious problem.

It is surrounded by a layer of collagen called vitreous membrane separating it from the rest of the eye. it makes up four-fifths of the volume of the eyeball.

Vitreous detachment Vitreous detachment is the separation of the eye's internal clear gel (vitreous) from the eye wall or retinal. A posterior vitreous detachment (PVD) is a common problem of aging that may not require any treatment, other than watching for symptoms of the more serious problems such as retinal tear or retinal detachment.

Burst Blood Vessel in Eye A condition known as a subconjunctival hemorrhage is caused by burst blood vessel in eye. The hemorrhage occurs under the clear surface of the eye known as the conjunctive and since the conjunctiva doesn't absorb blood very quickly, it becomes trapped under the transparent surface.

Intraventricular Hemorrhage What is intraventricular hemorrhage? Intraventricular hemorrhage (IVH) of the newborn is bleeding into the fluid-filled areas, or ventricles, surrounded by the brain. The condition is most often seen in premature babies, and the smaller and more premature the infant, the higher the risk for IVH.

Vitreous Detachment Defined Usually the fibers break, allowing the vitreous to separate and shrink from the retina. This is a vitreous detachment. In most cases, a vitreous detachment, also known as a posterior vitreous detachment, is not sight-threatening and requires no treatment. vitreous detachment is a common condition that usually affects people over age 50, and is very common after age 80. People who are nearsighted are also at increased risk. Those who have a vitreous detachment in one eye are likely to have one in the other, although it may not happen until years later.

Retinal Artery Occlusion Obstruction of the retinal vascular lumen by an embolus, thrombus or inflammatory/ traumatic vessel wall damage or spasm. Giant cell arteritis may also be associated with this condition. Occlusion of the bloodflow results in severe loss of vision due to oxygen starvation of the retinal tissues and eventual cell death.

Retinal Hemorrhage Retinal hemorrhage is the abnormal bleeding of the blood vessels in the retina, the membrane in the back of the eye. The retina is the part of the eye that converts light into nerve signals that are processed by the brain into visual images. The retina is the inside surface of the back of the eye, consisting of millions of densely arranged, light-sensitive cells called rods and cones.
