  • Abstract
  • Look Inside

We examined 27 eyes of nonexudative age-related macular degeneration by indocyanine green angiography. All the eyes showed hypofluorescent patches due to filling delay or defect in the choriocapillaris in a wide area exceeding the degenerative lesions. The choroidal veins showed dilatation or irregularity in caliber in 19 eyes (70%). Venovenous anastomosis was present in 21 eyes (78%) . These findings appeared to show the frequent presence of circulatory disorder in the choriocapillaris and choroidal veins in age-related macular degeneration.
