Retinal Vascular Diseases: Causes, Symptoms, and Treatment
Retinal vascular diseases refer to a group of conditions that affect the blood vessels in the retina, the light-sensitive tissue at the back of the eye. These diseases can lead to vision loss if not properly diagnosed and treated. At Hashemi Eye Care, we specialize in diagnosing and managing retinal vascular diseases, providing personalized care to help preserve your vision and maintain overall eye health.
What Is Retinal Vascular Disease?
The retina relies on a network of tiny blood vessels to function correctly. When these blood vessels are damaged or compromised, it can lead to vision problems and, in severe cases, blindness. The most common types of retinal vascular diseases include:
Retinal Vein Occlusion (RVO): This occurs when a vein in the retina becomes blocked, leading to swelling, bleeding, and vision problems.
Retinal Artery Occlusion (RAO): A blockage in a retinal artery can cause sudden and severe vision loss.
Diabetic Retinopathy: A complication of diabetes that damages the blood vessels in the retina. Learn more on our Diabetic Retinopathy page.
Hypertensive Retinopathy: High blood pressure can cause damage to the retinal blood vessels, leading to vision issues over time.
Retinal vascular diseases are serious and often require prompt treatment to prevent permanent damage.
Common Symptoms of Retinal Vascular Disease
The symptoms of retinal vascular diseases vary depending on the severity and type of the condition but may include:
Sudden or gradual vision loss
Blurry or distorted vision
Dark spots or floaters in your field of vision
Flashing lights
A shadow or curtain over part of your vision
If you experience any of these symptoms, it’s important to seek immediate medical attention. Early diagnosis can significantly improve your chances of maintaining vision.
Diagnosing Retinal Vascular Disease
At Hashemi Eye Care, we use advanced diagnostic technology to identify retinal vascular diseases early and accurately. Our diagnostic tools include:
Fluorescein Angiography: A dye test that highlights blood vessels in the retina to detect blockages or leaks.
Optical Coherence Tomography (OCT): A non-invasive imaging test that provides detailed cross-sectional images of the retina to detect swelling or other abnormalities.
We recommend regular Comprehensive Eye Exams for patients at risk of retinal vascular diseases, such as those with diabetes or hypertension.
Treatment Options for Retinal Vascular Disease
Treatment for retinal vascular diseases depends on the type and severity of the condition. At Hashemi Eye Care, our expert team will tailor a treatment plan that meets your specific needs. Common treatments include:
Intravitreal Injections: Medications are injected directly into the eye to reduce swelling and prevent further blood vessel damage. Anti-VEGF drugs like Bevacizumab (Avastin) or Ranibizumab (Lucentis) are commonly used to manage conditions like retinal vein occlusion and diabetic retinopathy.
Laser Therapy: Laser treatment can seal leaking blood vessels or destroy abnormal ones to prevent further damage to the retina. This treatment is often used for diabetic retinopathy.
Surgery: In severe cases, such as with retinal detachment or hemorrhaging, surgery may be necessary to repair the damage and restore vision.

Medications for Retinal Vascular Disease
Several medications may be prescribed to manage retinal vascular diseases, including:
Anti-VEGF injections: To prevent abnormal blood vessel growth and leakage. Common drugs include Bevacizumab, Ranibizumab, and Aflibercept (Eylea).
Steroid eye drops: These help reduce inflammation in cases of retinal vein occlusion or hypertensive retinopathy. Learn more about these medications on our Medication Guide page.
Early intervention with these treatments can prevent further damage to your retina and preserve your vision.
Risk Factors for Retinal Vascular Disease
Several factors can increase your risk of developing retinal vascular disease, including:
Diabetes: A leading cause of retinal vascular issues, particularly diabetic retinopathy. Learn how to manage this condition on our Diabetic Retinopathy page.
High blood pressure (hypertension): Uncontrolled hypertension can damage the blood vessels in the retina, leading to hypertensive retinopathy.
High cholesterol: Elevated cholesterol levels can increase the risk of artery blockages in the retina.
Smoking: Smoking can damage blood vessels throughout the body, including in the eyes.
It’s important to manage these risk factors to prevent the onset or progression of retinal vascular disease. Visit our Eye Health page for tips on maintaining overall eye health.
Preventing Retinal Vascular Disease
While some risk factors like age cannot be controlled, there are several steps you can take to reduce your risk of retinal vascular disease:
Control diabetes: Keep your blood sugar levels in check to prevent diabetic retinopathy.
Manage blood pressure and cholesterol: Regular checkups with your healthcare provider can help you keep these under control.
Quit smoking: Smoking cessation reduces your risk of vascular diseases throughout the body, including the eyes.
Regular eye exams: Early detection is key to preventing long-term damage.
To maintain optimal eye health and prevent retinal vascular disease, schedule regular Comprehensive Eye Exams at Hashemi Eye Care.
When to See a Doctor
It’s important to seek immediate medical attention if you experience:
Sudden vision loss
Persistent blurriness or distorted vision
Flashes of light or floaters
Dark spots in your field of vision
These could be signs of serious retinal issues such as retinal artery occlusion or retinal detachment, which require urgent care.
FAQs About Retinal Vascular Disease
Can retinal vascular disease cause permanent vision loss?
Yes, untreated retinal vascular disease can lead to permanent vision loss. However, early detection and treatment can often prevent further damage.
How often should I have an eye exam if I’m at risk for retinal vascular disease?
If you have risk factors like diabetes or hypertension, we recommend having an eye exam at least once a year to monitor for any signs of retinal damage.
Is laser therapy for retinal vascular disease painful?
Laser therapy is typically performed under local anesthesia, so you shouldn’t feel pain during the procedure. You may experience mild discomfort afterward.
