SCORE2 Study for Retinal Vein Occlusion

SCORE2 Study for Retinal Vein Occlusion

People with a retinal vein occlusion experience macular edema (swelling in the center of the retina, the thin light-sensitive tissue at the back of the eye) from blockage in a large retinal vein. This blockage is called a central retinal vein occlusion (CRVO). Retinal veins drain blood away from the retina back to your heart. A blockage in one of the large retinal veins (central retinal vein occlusion-CRVO) can result in fluid in the center of the retina (macular edema). This can result in decreased vision in that eye.

This research study will compare the drugs Eylea® (aflibercept) and Avastin® (bevacizumab) for treatment of macular edema due to CRVO. Eylea is a drug that has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of macular edema due to CRVO. Avastin is a drug that has been approved by the FDA for the treatment of some types of cancer but it has not been approved for use in the eye. However, since 2006, Avastin has been used to treat a wide variety of eye problems, including CRVO. Avastin interferes with the growth of new vessels and prevents leakage of fluid from new blood vessels. Both Eylea® and Avastin® are proteins made in a laboratory and are thought to decrease the macular edema by decreasing the activity of vascular endothelial growth factor (VEGF) in the eye. Thus, these drugs are known as anti-VEGF drugs and are given via injections into the eye.

A total of about 360 people are expected to participate in this study nationally, including up to 10 at the Medical College of Wisconsin/Froedtert Hospital.
