Characteristics of Indocyanine Green Angiography in Exudative Age-related Macular Degeneration

摘要

Objective:To observe the characteristics of indocyanine green angiography(ICGA)in exudative age-related macular degeneration(AMD).Methods:Thirty-one cases(39 eyes)were diagnosed as exudative AMD by ocular examination,fundus color photography,fundus fluorescein angiography(FFA)and ICGA.Their ages ranged from 50 to 82 years and visual acuities from FC/30cm to 0.7.We analyzed and compared the characteristics of ICGA and FFA in these patients.Results:of 26 eyes with ccult choroidal neovascularization (CNV)by FFA,15(57.7%)had classic CNV by ICGA.Of 4 eyes with serous retinal pigment epithelial detachment(PED)without CNV by FFA,1 had serous PED with classic CNV by ICGA.The hyperfluorescence of the scar staining was detecfed by ICGA.Conclusion:ICGA adds clinically useful information and is an important adjunct in the evaluation,classification,and laser treatment of patients with occult CNV in AMD.
