What Is Retinal Vein Occlusion?
A retinal occlusion means that one of the blood vessels that supports your retina is blocked by a clot, the hardening of the blood vessels, or small pieces of cholesterol. In a healthy retina, nutrient-rich blood enters through the central retinal artery and drains the nutrient-poor blood back out through the central retinal vein. A blockage interrupts the regular exchange of nutrients and waste from the eye.
This is a serious condition characterized by blurry or distorted vision in all or part of the visual field and even severe vision loss. Changes in your vision, especially sudden ones, should not be ignored. Seek treatment immediately.
A retinal vein occlusion (RVO) affects the blood vessels that carry blood away from the retina. When a vein becomes blocked, blood cannot exit, which, as blood builds up in the retina, causes swelling. The swelling, in turn, leads to vision loss. Blockages can be partial or complete and will determine the severity of vision loss.
An RVO is divided into two types: central and branch, depending on which type of vein is being affected. Central retinal vein occlusion means the main vein is blocked, while branch indicates blockage of a smaller vein.
Treatments for Retinal Vein Occlusion
Prevention is the best treatment for retinal vein occlusion. Maintaining good overall health and managing underlying conditions such as glaucoma and diabetes helps prevent blockages in the blood vessels that support your retina.
Even though the visual prognosis can be poor for a retinal vein occlusion, several treatment options are still available to help preserve your vision. By partnering together on a regular basis, the retina care team at Vance Thompson Vision will work with you to create a care plan for your specific condition and overall health.
