Frequently Asked Questions (FAQ) :
1. Can Retinal Artery Occlusion be prevented?
While RAO cannot always be prevented, managing risk factors like high blood pressure, diabetes, and cholesterol can reduce the risk. Regular eye checkups, especially for those with cardiovascular conditions, are crucial.
2. How soon should I seek treatment after experiencing symptoms of RAO?
RAO is a medical emergency. Immediate treatment is essential to minimize the risk of permanent vision loss. Seek medical attention as soon as symptoms occur.
3. Will my vision return after treatment?
In some cases, partial vision can be restored if treatment is provided quickly. However, delayed treatment may lead to permanent vision loss.
About Retinal Artery Occlusion
Retinal Artery Occlusion (RAO) is a serious eye condition caused by a blockage in the arteries that supply blood to the retina. The retina is the light-sensitive layer at the back of the eye, essential for vision. When a blockage occurs, it deprives the retina of oxygen, leading to vision loss. Early diagnosis and treatment are critical to preserving vision. Dr. Suraj Munjal, a leading ophthalmologist, specializes in diagnosing and treating RAO effectively.
Causes of Retinal Artery Occlusion
RAO is usually caused by an embolism or blood clot that restricts blood flow. Common risk factors include:
- Atherosclerosis (hardening of the arteries)
- High blood pressure
- Diabetes
- High cholesterol
- Heart disease
- Smoking
Other rare causes can include trauma to the eye or inflammatory diseases that affect blood vessels.
Types of Retinal Artery Occlusion
-
Central Retinal Artery Occlusion (CRAO): This occurs when the main artery supplying blood to the retina is blocked, leading to significant and sudden vision loss.
-
Branch Retinal Artery Occlusion (BRAO): This happens when a smaller branch of the retinal artery is obstructed. Although it typically affects only part of the vision, it still requires urgent care.
Both conditions can lead to permanent vision damage if not treated promptly.
Symptoms of Retinal Artery Occlusion
The symptoms of RAO usually come on suddenly and may include:
- Sudden, painless loss of vision in one eye
- Partial or complete vision loss depending on the type of occlusion
- Blurred vision
- A sensation of a dark shadow or curtain covering part of your vision
If you experience any of these symptoms, it’s crucial to seek immediate medical attention. Early intervention can prevent further damage.
Diagnosis of Retinal Artery Occlusion
Diagnosing RAO involves a comprehensive eye exam, and Dr. Suraj Munjal uses the latest diagnostic tools to assess the condition. Diagnostic methods may include:
- Ophthalmoscopy: A direct look at the retina to detect blockages.
- Fluorescein Angiography: A dye is injected into the bloodstream to help highlight the blood vessels in the retina.
- Optical Coherence Tomography (OCT): High-resolution imaging to view the retina’s structure.
- Blood Tests: To check for underlying health conditions such as high cholesterol, diabetes, or blood clotting disorders.
Treatment for Retinal Artery Occlusion
Immediate treatment is critical in preventing permanent vision loss. Treatment options vary depending on the severity of the occlusion but may include:
- Eye massage to dislodge the clot and restore blood flow
- Intraocular pressure-lowering medications to improve circulation
- Intravitreal injections to reduce retinal swelling
- Hyperbaric oxygen therapy for some cases
- Managing underlying conditions such as hypertension, diabetes, or cardiovascular diseases to prevent recurrence
