The branch retinal vein occlusion refers to the blockage of the tiny veins within the retina. In some cases, the blockage may take place in the main veins, explains GetEyeSmart.org.
Branch retinal vein occlusion occurs when the arteries of the retina that have been thickened through atherosclerosis exert excess pressure on the veins of the retina. The blockage of veins may result in the death of some eye nerve cells. However, this condition is treatable. The first step in treating branch retinal vein occlusion, is finding out its cause, states eyeSmart by the American Academy of Ophthalmology.
Usually, the eye doctors recommend an observation period, especially after the diagnosis. Many people often experience swelling on the central macular part during the development of branch retinal vein occlusion. The swelling, also referred to as macular edema, can last more than 12 months, adds eyeSmart.
The most appropriate treatment for eliminating the macula swelling is focal laser surgery. With this treatment, the eye doctor applies the laser burns at the macula region with fluid leakage. The major aim of laser surgery is to enhance vision stabilization by sealing any blood vessel interrupting the normal functionality of the macula. Other treatments of edema are Lucentis and Avastin injections. In addition, steroids such as Ozurdex can also be used.
