Choroidal filling in age-related macular degeneration: indocyanine green angiographic findings.
We studied the choroidal filling patterns in 145 patients with age-related macular degeneration (AMD), looking for a correlation with choroidal neovascularization (CNV). We found a correspondence in 71% of cases between the site of the CNV and watershed areas and in 59% of cases between the CNV and areas of 'delayed choroidal filling'. These data support the hypothesis of a relationship between areas of presumed choroidal ischemia and evolution of AMD complicated with CNV.
