The doctor will explain what the procedure is and will ask you if you understand or have any questions. A nurse will also speak with you and answer any questions that you may have. The nurse will also take your blood pressure and pulse. It is important to tell the nurse and the doctor if you have any allergies to any medications or foods before you have the fluorescein angiography. The nurse will be in the room with you while the doctor is performing the test.
Some patients feel nausea during the procedure but it usually lasts for just a few seconds.
If any of the dye escapes from a small vein when it is injected, it is possible for your skin to feel very warm and yellow blotches may appear. Allergic reactions to the fluorescein dye are very uncommon. If an allergy occurs, you will begin to develop a rash or feel an eruption of itchiness. The reaction is usually treated with an oral dose of an antihistamine. The test lasts for only five to ten minutes.
