Abnormal vitreous is often a causative factor in the development of retinal diseases including diabetic retinopathy, macular pucker, macular hole and retinal detachments. The surgery involves removing the vitreous gel from the center of the eye. It is important to be monitored closely for at least six months for the development of these conditions as prompt treatment can often minimize the vision damage caused by the abnormal blood vessels.Ī common surgery performed for abnormal retinal conditions of the eye is called vitrectomy. These conditions are more common with central retinal vein occlusions and can lead to sever vision loss, eye pain, nausea and vomiting and require prompt treatment. These abnormal blood vessels can lead to bleeding in the eye, retinal detachments and a severe type of glaucoma known as neovascular glaucoma. When a vein or artery is blocked, the retina is depleted of nutrients and oxygen which may cause the damaged retina to produce a growth factor which causes abnormal, friable blood vessels to develop. Vision can sometimes be restored with intraocular or periocular injections, laser and occasionally vitrectomy surgery. Unfortunately, this does not necessarily correspond to improved sight. Unfortunately, there is no proven way of reopening a blocked vessel to provide circulation and to repair the blocked retina. These tests may be critical in diagnosing and preventing other cardiovascular events. Certain tests may be necessary to look for blood cell abnormalities, blood vessel inflammation or other abnormalities in the cardiovascular system including the carotid arteries and heart. Blood vessel blockages are more common in patients with high blood pressure, diabetes and in smokers. In many cases, no specific cause of these blockages are identified.
If a branch of the artery or vein is blocked, often a portion of the vision is affected. If the central artery or vein is blocked, the entire vision is affected. If one of these blood vessels develops a blockage, the retina served by that vessel will not function normally, resulting in vision loss. In the retina, as in the rest of the body, there are small blood vessels that bring blood into the retina (the arteries) and small blood vessels that bring blood out of the retina (the veins).
