Ophthalmic advices:Angiography with fluorescein
|The angiography is used to diagnose and guide the treatment of diseases of the retina|
The fluorescein angiography is an ophthalmologic study from an analysis of the movement of vessels in the retina and operation, to diagnose diseases of the retina. This study determines in many cases the type of disease, the degree of involvement and treatment possibilities.
The action is produced through injection of a fluorescein dye called an arm vein. The dye travels through the body distributed by the vessels of the choroid and retina, initially in the arteries and veins after. The study photos of the retina are taken to see the contrast at different times of the study and identify healthy and abnormal areas.
The decision of the study should be in accordance with the patient and the ophthalmologist, it requires a complete eye examination with an examination with pupil dilation in order to check the retina and in many cases rely further studies. It is commonly used to study the function of the retina in specific diseases, such as macular edema in patients with diabetic retinopathy or vascular occlusions and the macular degeneration.
The method of fluorescein angiography is performed with a pipeline from a vein in the arm through which the dye is injected. The patient with dilated eyes, sitting in front of the camera and retinal images are taken at different stages according to the different periods in which the dye is happening. The study is quick, lasting approximately 10 minutes. The patient may reinstate your daily life easily.
