The eye contains a protein called vascular endothelial growth factor, or VEGF. The role of VEGF is to help grow new blood vessels.
Macular edema following retinal vein occlusion (RVO) is caused by an excess of VEGF in addition to vessel blockages. This leads to the abnormal blood vessel growth that can cause vision problems
Your doctor can detect changes or problems in your vision with a visual acuity test. Visual acuity tests find the smallest letters you can see on a standard eye chart. Visual acuity is the sharpness of your vision.
Visual acuity is expressed as a fraction such as 20/40 or a single number such as 1.5.
Following up with your doctor is necessary for tracking your vision over time and your progress with LUCENTIS.
This video is meant to show you a range of symptoms you may experience. Symptoms can vary depending on the severity level of the disease and will be unique for each person. If you experience any problems with vision, contact your Retina Specialist right away.
