  • Abstract
  • Look Inside

Indocyanine green (ICG) angiography was performed in 8 eyes of 8 patients with carotid artery occlusion. The arm-to-choroid circulation time ranged from 15 to 29 seconds. Intrachoroidal circulation time ranged from 12 to over 50 seconds. Both values were grossly prolonged than in normal eyes. Peripheral ICG angiography in 3 eyes showed delayed dye filling of watershed zone in 2 eyes and persistent nonperfusion in 1 eye via short posterior ciliary arteries. Seven eyes showed patchy areas of filling defect of the choriocapillaris. Two eyes showed dye staining of choroidal veins in the late phase of angiography. The findings show that carotid artery occlusion may result in retarded circulation or vascular occlusion in the choroid.
