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

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.

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 occult choroidal neovascularization (CNV) by FFA, 15 (57. 7% ) had classic CNV by ICGA. Of 4 eyes with serous retinal pigment epithelial detachment (FED) without CNV by FFA, 1 had serous FED 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.
