Purpose To discuss changes of macular choriocapillaris hemodynamics in AMD. Methods Eighty-six eyes of 86 patients underwent ICGA,including macular drusen in 15 eyes of 15 patients,exudative AMD in 52 eyes of 52 patients,atrophic AMD in 19 eyes of 19 patients,for the observation of macular choriocapillaris perfusion. Results Choriocapillaris filling phase (CFP) of exudative AMD was obviously longer than that of eyes with normal, atrophic AMD and drusen groups (P＜0.05). Forty eyes had local or extensive choroidal filling deficiency and prolongation, including 24 eyes of exudative AMD, 12 eyes of atrophic AMD,and 4 eyes of drusen group. Conclusion CFP of macula is prolonged and choriocapillaris perfusion is abnormal in AMD and macular drusen eyes. (Chin J Ocul Fundus Dis, 2002, 18: 116-118)
