. Indocyanine green angiography in age-related macular degeneration with fluorescein angiographyoccult neovascularization

摘要

Indocyanine green angiography (ICGA) has recently disclosed a new diagnostic approach to ARMD. The characteristics of the dye, which is fluorescent in the near infrared and wholely bound to blood proteins, have already proved useful for investigating choroidal abnormalities, besides haemorrhages, turbid fluids and retinal pigment epithelium. The method, therefore, appears indicated in exudative ARMD when occult choroidal new vessels are suspected. This study was designed to assess the ability of ICGA to detect CNV clearly, to study their angiographic characteristics and to establish the number of eyes eligible for laser treatment.
