Timeliness of diabetes mellitus type 2 and its chronic complications problem for modern medicine is doubtless. Diabetic retinopathy is a chronic microvascular complication of diabetes mellitus and is one of the leading causes of blindness in diabetic patients. Fluorescein angiography is one of the standard methods of the ophthalmic examination in diabetic patients. Fluorescein angiography is an important additional procedure nowadays though fundus examination is possible by means of direct and indirect ophthalmoscopy. The method is based on fluorescence phenomenon and on the ability of fluorescein contrast to penetrate retinal tissues if the permeability of blood-retinal barrier is affected. There are five phases of fluorescein angiography: arterial, arteriovenous, late venous, recirculation phase. Fluorescein angiography is of great value for practitioners in diabetic patients as it demonstrates special characteristics of retinal blood flow, provides images of retinal vessels and gives opportunity to evaluate their function.
