Retinal vein occlusion (RVO) happens when a vein that drains blood from the retina becomes blocked. Blood and fluid can leak into the retina and macula, which may blur or distort central vision. Southwest Eye Clinics in Mesquite evaluates and treats branch and central retinal vein occlusion for patients referred by their eye doctors. Return to the Southwest Eye Clinics home page for an overview of our retina services.
Branch Versus Central Vein Occlusion
RVO is grouped by which vessel is affected.
Both types can lead to macular edema, the swelling that most often reduces reading vision. RVO is also associated with glaucoma, high blood pressure, diabetes, and blood clotting disorders. Your doctor will review your medical history during the visit.
Symptoms Patients Notice
Symptoms may appear suddenly or worsen over days. Common complaints include blurry vision, a dark or empty area in part of the field of vision, and distorted straight lines. Some patients have mild symptoms and are diagnosed during a dilated exam. Any sudden change in vision should be reported promptly to your eye doctor.
How Evaluation Works at Our Office
Referred patients receive a dilated retina examination. Testing may include optical coherence tomography (OCT) to measure macular swelling, fluorescein angiography when needed to study blood flow, and blood pressure review with your primary doctor when risk factors are present. Results are shared with your referring physician so treatment stays coordinated. Visit Patient Care for office hours and what to bring to your appointment.
Treatment and Follow-Up
There is no single cure for RVO. Care focuses on treating macular edema and preventing further vision loss. Options may include intravitreal anti-VEGF injections, steroid implants, or laser therapy depending on the type and severity of occlusion. Some eyes need long-term monitoring even after initial improvement. Related conditions such as diabetic retinopathy and macular degeneration are managed separately but may coexist. Our retina surgeons discuss benefits and risks before starting therapy.
