Retinal vein occlusion (RVO) occurs when a vein carrying blood away from the retina is blocked. This blockage causes the vein to leak blood and fluid which collects in the macula, the area responsible for your central vision. When this fluid is trapped, you may experience blurry vision or a rapid loss of sight since the macula can no longer translate light into the images you usually see.
Because a retinal vein cannot be completely unblocked, there’s no 100% cure for RVO. However, working with a retina specialist like Dr. Esparaz of Envision Ophthalmology & Wellness can help treat complications of an RVO. The key is to seek medical attention immediately if you have sudden vision loss.
Anyone can be diagnosed with RVO, but if you have a condition that affects blood vessels, such as diabetes, high cholesterol, or high blood pressure, your risk increases. Some warning signs of RVO include:
Time is of the essence when you experience a retinal vein blockage. Getting on an ophthalmologist’s schedule as soon as possible is vital to protect your sight.
Retinal Injections for Retinal Vein Occlusion – In some cases, Dr. Esparaz will administer intravitreal injections of medication to the retina. Injections are performed under local anesthesia to ease any pain and discomfort.
Retinal Laser Therapy or Surgery – Laser therapy may be necessary to seal off blood vessels around the macula to prevent them from leaking and causing swelling. In addition, laser surgery is often used to address new blood vessel formation after a blockage has occurred.
