Characteristics of fundus fluoresceine angiography of subretinal cysticercosis

Objective To explore the characteristics of fundus fluorescein angiography (FFA) in patients of subretinal cysticercosis.Methods Patients diagnosed as subretinal cysticercosis confirmed by fundus photography and B scan,FFA were carried out and analyzed.Results During the arterial phase,the retinal vascular began filling and the lesion did not obscure or slightly obscure choroidal background fluorescence.During the venous phase,retinal vessels continue filling,capillary network clearly visible,and outline fundus lesions profile consistent with the subtinal cysticercosis.During the late phase,the surface of parasite tissue showed a strong fluorescence,retinal vessels gradually showed fuzzy linear strong fluorescence.Three patients with visible retinal capillary slight expanded and fluorescein leakage,Optic disk boundary were not clear and optic disk surface capillary leakage in 2 patients.Conclusions FFA can help us to judge the retina and cysticercosis in the anatomical position,understand the damage to retinal tissue,blood vessels,optic nerve,and differential diagnosed with related choroidal tumors and inflammatory disease.
