Blocked Blood Vessels in the Eye (Retinal Vascular Occlusion)
Causes, Symptoms, and Treatment Options
Blocked blood vessels in the eye, known medically as retinal vascular occlusion, occur when the vessels in the eye narrow or become blocked. This happens when the vessels supplying an important area of the eye become obstructed, and it can lead to vision loss. For those who want to learn more about blocked blood vessels in the eye, this article covers the causes, symptoms, and treatment options.
Causes
Blocked blood vessels in the eye are usually seen at an older age, but they can also occur in younger people. Some of the causes include:
High blood pressure: High blood pressure can narrow the vessels in the eye, leading to blockage.
Diabetes: Diabetes can damage the blood vessels in the eye and lead to blockage.
High cholesterol: High cholesterol can clog the blood vessels in the eye, causing blockage.
Eye infections: Eye infections can cause inflammation and blockage of the vessels in the eye.
Eye injuries: Eye injuries can damage the blood vessels in the eye and lead to blockage.
Symptoms
- Blocked blood vessels in the eye most often show up as vision loss in one eye. Other symptoms include:
- Blurred vision
- Unstable or distorted vision
- A difference in image quality between the two eyes
- Painless vision loss
- Changes in color perception
Treatment Options
Treatment for blocked blood vessels in the eye depends on the cause and severity of the blockage. Treatment options include the following:
Medication: Medications used to treat blocked blood vessels in the eye help control underlying factors such as high blood pressure, diabetes, or high cholesterol. Medications can also help reduce the damage caused by the blockage. These medications are usually given orally or by injection.
Laser treatment: Laser treatment is used to repair tissue damaged by the blockage in the eye. This treatment method uses high-energy laser beams to repair tissue damaged by the blockage. Laser treatment is usually quick and painless.
Injections: Medications injected into the eye can be used to reduce the damage caused by the blockage. These medications can help repair tissue damaged by the blockage in the eye. Injections are usually performed under local anesthesia and are painless.
Surgery: If the blockage in the eye isn't resolved with medication, laser treatment, or injections, surgery may be necessary. Surgery is used to repair or remove tissue damaged by the blockage. Surgery is usually performed under general anesthesia and is a more involved procedure.
Treatment options can vary based on the patient's condition, the severity of the blockage, and its cause. If you notice symptoms of blocked blood vessels in the eye, it's recommended that you see an eye doctor as soon as possible. Your eye doctor will assess your condition and recommend the most suitable treatment.
