Abstract

This paper describes an improvement in the image system for near infrared videoangiography as compared with a previous intensified TV camera incorporated in a standard fundus camera. The new system uses a cooled CCD camera with 1152 X 770 elements. Because of a very low readout noise and variable time integration, this camera was used at very low light. This avoided the potential hazard to the eye resulting from over exposure and increased the patient's physical comfort during ophthalmic imaging. This paper reports the results of the first phase of the work in which several sequences of ocular fundus images were analyzed.
