Understanding Central Retinal Artery Occlusion (CRAO) - Bilateral

Central Retinal Artery Occlusion (CRAO) is a medical condition where the central retinal artery, which supplies blood to the retina, is blocked, leading to loss of vision. Bilateral CRAO occurs when both eyes are affected. This is a rare condition that requires immediate medical attention to prevent permanent vision loss.

1. Causes: Bilateral CRAO is usually caused by a blood clot in both retinal arteries. This can occur due to several factors, including high blood pressure, diabetes, heart disease, and smoking. In some cases, it can also be caused by an autoimmune disorder or a blood disorder.
2. Symptoms: The most common symptom of bilateral CRAO is sudden loss of vision in both eyes. The vision loss can be total or partial, and it usually occurs without warning. Other symptoms include eye pain, headache, and dizziness.
3. Diagnosis: Bilateral CRAO is diagnosed through a comprehensive eye exam, including a visual acuity test, a dilated eye exam, and imaging tests such as an MRI or CT scan. Blood tests may also be done to check for underlying medical conditions that could be causing the condition.
4. Treatment: There is no specific treatment for bilateral CRAO. However, immediate medical attention is required to prevent permanent vision loss. Treatment options may include medications to dissolve blood clots, high doses of oxygen therapy, or surgery to restore blood flow to the retina.
5. Prevention: The best way to prevent bilateral CRAO is to manage underlying medical conditions that increase the risk of developing the condition. This includes controlling high blood pressure, managing diabetes, and quitting smoking. Regular eye exams are also recommended to detect any early signs of the condition and prevent permanent vision loss.

If you experience sudden vision loss in both eyes, it is important to seek immediate medical attention. Early diagnosis and treatment can help prevent permanent vision loss and improve your overall quality of life.
