Continual Monitoring of Fluorescein Angiography

 A system has been developed which enables continuous monitoring and recording of circulating fluorescein in the retinal blood vessels. This is achieved with minimal modification of a Zeiss fundus camera. A night vision television camera (Ikegami) is used with illumination provided by the standard observation light of the fundus camera. This method offers advantages over standard fluorescein angiography in patient comfort, information obtained and the immediate evaluation of the fluorescein angiograms being available.
