  • Characteristics of fundus angiography in acute retinal necrosis syndrome

    ObjectiveTo observe the characteristics of images of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) in patients with acute retinal necrosis syndrome (ARNS), and investigate the applied value of FFA and ICGA in clinical diagnosis.MethodThe data of the ocular fundus, FFA and ICGA of 20 patients (28 eyes) with ARNS were retrospectively analyzed.ResultsThe images of FFA indicated hyperfluorescence of optic disc in 24 eyes (85.71%) at the late phase; widespread retinal vascular occlusion at the peripheral focus in 23 eyes (82.14%) with some occlusive vascular shadow and the fluorescein in some white-line-like blood vessels; fluorescent leakage at the junction of normal and abnormal retina in 22 eyes (78.57%); retinal detachment in 20 eyes (71.42%), including 9 with retinal hole (45% of the patients retinal detachment); and macular cystoid edema in 8 eyes (28.57%). The images of ICGA showed hyperfluorescence of optic disc in 8 eyes (28.57%) including 5 with dotted staining at the optic disc at the late phase; unclear choroidal vasculature in the peripheral focus in 20 eyes (71.42%); and choriodal scattered hypofluorescent patch at the focus area in 19 eyes (67.85%). At the late phase of ICGA, some intravascular emboli and segments of retinal vascular occlusion were clearly demonstrated. ConclusionThe main manifestations of patients with ARNS in the images of FFA were hyperfluorescence of optic disc and retinal vascular occlusion; and unclear choroidal vessels and scattered hypofluorescent patch at the focus area.Combination of FFA and ICGA is helpful to understand the extent of the lesions and the relations between choroids and retina, which has great significance in diagnosing ARNS.(Chin J Ocul Fundus Dis, 2005,21:100-102)
