Fluorescein Angiography, Wide Field Angiography and Indocyanine Green Angiography in Behcet Uveitis

In Behcet’s disease, the anterior and posterior segments of the eye may be affected separately or together. Fundus fluorescein angiography should be performed in addition to ophtalmoscopic examination for early diagnosis and treatment of ocular involvement. Fundus fluorescein angiography (FFA) is the gold standard for the evaluation of retinal vascular system and pathologies. Fundus fluorescein angiography is more sensitive than fundus examination in the detection of vasculitis, and angiographic involvement is always more common than clinical involvement. Fluorescein angiography may reveal leakage from retinal veins in eyes whose visual impression is not affected and the fundus examination is normal. The absence of vascular leakage with fluorescein angiography indicates that the disease is in a completely inactive period. Because of the development of blindness due to posterior segment involvement, early detection of the disease with fundus angiography and the initiation of the treatment are successful in terms of visual prognosis. It has an important place in terms of early activation of patients with FFA in the early diagnosis of eye involvement and follow-up of the disease and treatment. Wide-field imaging angiography imaging of retinal periphery revealed the importance of lesions in retinal periphery and peripheral areas invisible by standard angiography. The use of indocyanine green angiography in Behcet uveitis is limited.
