Funduscopy is a routine ophthalmology test and the results are usually available within an hour of the end of the test. In larger hospitals, the report may be delayed due to the large number of patients, but usually does not exceed 24 hours. This test is mainly used for the diagnosis of vascular diseases of the fundus, such as retinal vein obstruction, diabetic retinopathy, retinal or choroidal neovascular disease. The principle of this test is to determine the presence or absence of neovascularization, ischemic areas or areas of no perfusion by means of a specific fluorescent contrast agent that travels through the retinal vessels. With this test, accurate guidance can be given on the next step in the treatment plan. Therefore, if fundus disease is present, fundus angiography can be perfected.
