Objective To observe and estimate the image characters of indocyanine green angiography (ICGA) and fundus fluorescein angiography (FFA) in atrophic age-related macular degeneration(AMD) and macular drusen. Methods FFA, ICGA and fundus photography were performed on 95 eyes of 73 atrophic AMD patients, in cluding 19 patients (26 eyes) with depigmentation and atrophy of retinal pigment epithelium (RPE), 15 (30 eyes) with macular drusen, and 39 (39 fellow eye) with unilateral exudative AMD.Results In 26 eyes with depigmentation and atrophy of RPE, the result of FFA of 24 eyes with depigmentaion showed patch hyperfluore scence, and of ICGA showed patch hyperfluorescence and hypofluorescence on the late photographs; in 2 eyes with maplike atrophy of RPE, the result of FFA showed patch hyperfluorescence, and of ICGA showed choriocapillaris defect with sharply demarcated boundaries and hypofluorescence of large choroidal vessels. In 30 eyes with macular drusen, the result of FFA of 8 eyes with hard drusen showed hyperfluorescence, and of ICGA showed patch and spot hyperfluorescence; the result of FFA of 16 eyes with soft drusen showed hyperfluorescence, and of ICGA showed persistent patch hypofluorescence intermixed with cluster hyperfluorescence; and the result of FFA of 6 eyes with both soft and hard drusen showed hyperfluorescence, and of ICGA showed patch hyperfluorescence intermixed with hypofluorescence. When it was hypofluorescence in ICGA in patients with macular drusen, larger quantity and range of fluorescence were found in FFA than in ICGA; when it was hyperfl uorescence in ICGA, smaller quantity and range of fluorescence were found in FFA than in ICGA. In 39 fellow eyes of unilateral exudative AMD, 32 or 31 eyes, examined by ICGA or FFA, had abnormal fluorescence of drusen and depigmentation and atrophy of RPE damage.Conclusions Simultaneous examination of IC GA and FFA can be useful for accurate evaluation of fundus image characters of types of angiography in atrophic AMD.(Chin J Ocul Fundus Dis，2003，19：79-82)
