Frequently Asked Questions (FAQ) :
1. Is retinal angiography painful?
The procedure itself is not painful, but some patients may experience mild discomfort during the dye injection or temporary blurriness in vision afterward.
2. How long does the retinal angiography procedure take?
The procedure usually takes 30 to 45 minutes, including preparation time.
3. Are there any side effects of retinal angiography?
Most patients experience no significant side effects, but some may have mild nausea, light sensitivity, or a yellowish tint to their skin temporarily due to the dye.
About Retinal Angiography
Retinal angiography is a diagnostic test that allows doctors to visualize the blood vessels in the retina, the light-sensitive tissue at the back of the eye. This test is essential for detecting various eye conditions, such as diabetic retinopathy, macular degeneration, and retinal vein occlusion. Using a special dye and camera, retinal angiography provides detailed images of retinal blood flow, helping in the early detection and treatment of eye diseases.
Causes Requiring Retinal Angiography
Retinal angiography is often recommended to diagnose or monitor the following conditions:
- Diabetic Retinopathy: Damage to the retinal blood vessels due to diabetes.
- Age-Related Macular Degeneration (AMD): Deterioration of the central part of the retina.
- Retinal Vein Occlusion: Blockage of veins that drain blood from the retina.
- Uveitis: Inflammation of the middle layer of the eye.
- Retinal Detachment: Separation of the retina from its supporting tissue.
Types of Retinal Angiography
There are two main types of retinal angiography:
- Fluorescein Angiography (FA): In this type, fluorescein dye is injected into the bloodstream to highlight the blood vessels in the retina. It helps in diagnosing blood vessel leakage, blockages, and other abnormalities.
- Indocyanine Green Angiography (ICGA): This method uses indocyanine green dye, which provides more detailed imaging of deeper blood vessels in the eye, especially for detecting conditions like choroidal neovascularization (common in macular degeneration).
Symptoms Indicating Retinal Angiography
Retinal angiography is recommended when patients experience symptoms such as:
- Blurred or distorted vision
- Dark spots or floaters
- Difficulty seeing at night
- Sudden vision loss
- Eye pain or discomfort
- Persistent flashes of light or wavy vision
Diagnosis Through Retinal Angiography
During the procedure, a dye is injected into the patient’s arm, which travels to the eye. A special camera captures images as the dye moves through the retinal blood vessels. These images help identify abnormalities like:
- Blocked or damaged blood vessels
- Fluid or blood leakage in the retina
- Inflammation or swelling in the eye
Treatment After Retinal Angiography
Based on the results of the angiography, Dr. Suraj Munjal will recommend a personalized treatment plan, which may include:
- Laser Treatment: To seal leaking blood vessels or to shrink abnormal ones.
- Injections: Anti-VEGF injections can reduce abnormal blood vessel growth in conditions like AMD.
- Surgery: In more advanced cases, surgical interventions may be needed to repair damaged areas of the retina.
