. Preinjection fluorescence in indocyaninegreen angiography

摘要

Preinjection fluorescence of ocular structures, including pseudofluorescence and autofluorescence, has been well documented in fluorescein angiography1. The purpose of this study was to verify whether preinjection fluorescence can be also observed in indocyanine green (ICG) angiography. The present digital systems for ICG angiography are highly sensitive to near infrared emissions. They could be also capable of detecting autofluorescent emissions of chorioretinal structures in the near infrared range.
