Retinal Vein Thrombosis (RVT) is a medical condition characterized by the formation of blood clots within the veins that carry deoxygenated blood away from the retina, the light-sensitive tissue located at the back of the eye. This condition typically occurs in individuals with certain risk factors, including older age, high blood pressure, diabetes, smoking, atherosclerosis, or a history of blood clotting disorders.
When a blood clot forms in the retinal veins, it can obstruct or impede the flow of blood and oxygen to the retina, leading to a variety of associated symptoms and potential complications. Some common symptoms of retinal vein thrombosis include sudden, painless vision loss or blurry vision in one eye, distortion or distortion of images, and the presence of floaters (small dark spots or lines in the field of vision).
The severity and prognosis of retinal vein thrombosis depend on the size, location, and extent of the blood clot. In some cases, small clots may dissolve on their own, and vision can improve gradually. However, larger or more significant clots may cause permanent damage to the retina, leading to vision loss that is irreversible.
Treatment for retinal vein thrombosis may involve managing underlying risk factors, such as controlling blood pressure or diabetes. Prescription medications, such as anticoagulants or anti-inflammatory drugs, can also be administered to dissolve the blood clot and reduce inflammation. In severe cases, laser surgery or other surgical interventions may be necessary to restore blood flow and preserve vision.
