What is fluorescein angiography?
fluorescein angiography, also called eye angiography and photographs of the retina, is a diagnostic eye test that uses a specific fluorescent dye and a special camera for retina photography, light -reacting light located in the back of the eye. This specialized procedure is primarily used to determine whether retinal blood vessels receive adequate circulation. Fluorescein angiography may also be performed to ensure permanent recording of the eye vessels of the eye so that doctors will help in confirmation of diagnosis or to provide correct treatment instructions.
The fluorescein process of angiography begins when eye drops are inserted into the eye to support the dilation of pupils. The first series of photos is then taken from inside the eye. Furthermore, a yellow dye soluble in water called fluorescein sodium will be injected into the arm or hand. Fluorescein in a blue light with fluorescence pulls a fluorescent chemical compound. After Fluorescein Injection, a special camera that releases blue light, acquisitionIt is another group of photographs when the dye passes through the blood vessels of the retina. The scans are taken quickly, for 60 seconds. After fluorescein injection, further scanning can be carried out for up to 20 minutes.
Invasive procedure, 5 to 10% of patients with fluorescein angiography states side effects, with the most common complaints are nausea and vomiting. Many patients report mild pain when the needle is inserted into the arm, and also experiences a warm feeling when the dye enters the body. However, these symptoms fled. After injection of fluorescein dye, the skin may have a yellowish tone for several hours. Patients will also experience a change in urine color daily or two after the procedure, with a darker and potentially orange color. Patients should be prepared for the experience of blurred vision up to twelve hours after fluorescein angiography.
fluoscein angiography that brings normal results means that in the blood vessels of the NedIt is about any leaks or blockages and that the blood vessels seem to have a typical size. The abnormal result of fluorescein angiography can be caused by many factors, including diabetes, macular degeneration, swelling of the optical disk and circulatory problems. Both diabetes and macular degeneration can cause retina blood vessels to leak fluid or blood. Fortunately, with laser treatment, retinal abnormalities can be successfully repaired as a result of these diseases and the results of treatment can be monitored by other fluorescein angiographic procedures.
