Fluorescein angiography is a diagnostic exam that takes a photograph of the retina and the back of the eye. It involves the intravenous administration of a contrast agent (fluorescein) into a vein in the patient’s forearm, arm or hand.
It is a very important exam for diagnosing or providing more information to treat various eye diseases, such as:
- Diabetic retinopathy
- Arterial hypertension
- Arterial Occlusions and Venous Thrombosis
- Age-related macular degeneration (AMD)
- Retinal Dystrophies
Although it is considered a safe and quick exam, the patient is advised to be accompanied by a friend or relative, as the ocular dilation may make them temporarily sensitive to light, or with difficulty focusing on things. Due to the injection of contrast agent, some patients may also experience nausea and temporary yellowing of the skin and urine.
