Purpose To investigate the clinical characteristics of the Stargardt is disease and to evaluate the value of the fundus fluorescein angiography (ICGA) in Stargardt is disease. Methods Routine eye examination,VEP,ERG,EOG,and perimetry were performed in 25 cases(30 eyes) of Stargardtprime;s disease (15 men and 10 women) aged 12-41,on an average of 23.FFA was done in 15 cases (30eyes),and ICGA was done in 10 cases (20 eyes). Results Visual acuity was below 0.1 for 90.0% of the cases.Every eye showed macular lesions that wrere horizontal ellipse in shape,1.3-3.2PD in horizontal diameter and tinged with metal or beated copper color.Fundus flavimaculatus was found in 84.0% of the cases.On fluorescein angiography,window defect hyperfluorescence was found in the macular lesion of ocular fundus,with typical quot;bullprime;s eyequot; pattern.A quot; dark choroidquot; was revealed in 91.70% of the whole cases.On indocyanine green angigraphy,hypofluorescent area appeared at the macula in the early phase,even in very early stage of the Stargardtprime;s disease.Areas of fundus flavimaculatus were also hypoflurescent that became more apparent in the later phase. Conclusion Fluorescein angiography combined with indocyanine green angiography was useful for studying the clinical features and the pathological mechnism of the Stargardtprime;s disease.
