Blockage of one of the venous branches in the retina is called may cause vision loss and other complications (H2).
What Is Branch Retinal Vein Occlusion? (H3)
The retina is a thin tissue in the back of the eye that consists of nerve cells. These nerve cells capture images that you see, much like the film of a camera. The center portion of the retina is called the macula and is where our best vision comes from. Our ability to do things like driving and reading comes from the function of the nerve cells in the macula. Blockage of one of the venous branches in the retina is called a branch retinal vein occlusion (BRVO), and may cause vision loss and other complications. Males and females are, in general, affected equally. Most retinal vein occlusions occur after the age of 50, although younger patients are sometimes seen with this disorder.
Risk Factors If BRVO Goes Untreated
The symptoms of a branch retinal vein occlusion depend on the specific venous branch. Common symptoms include blurred vision or changes in a portion of the visual field (peripheral vision). Occasionally the branch retinal vein occlusion will affect a vein draining a portion of the retina away from the central vision and will not cause any symptoms.
Image Description
As a result of a branch retinal vein occlusion, there is often a significant amount of blood within the retina that obscures complete visualization of the retina. The blood will often gradually absorb, but this may take several months. In addition, there are three other common complications of branch retinal vein occlusion that threaten vision: macular edema (swelling from leaking blood vessels), macular ischemia (loss of blood flow) and neovascularization (growth of new abnormal blood vessels in response to poor blood flow).

P. Laser treatment usually results in stabilization or even regression of the blood vessel growth. The bleeding will sometimes clear on its own, but if it does not, then an operation to remove the blood and the vitreous gel, called a vitrectomy, is sometimes performed. In severe cases of abnormal blood vessel growth, the retina may be pulled away from the wall of the eye (tractional retinal detachment), and this may require surgical repair.
