title: New developments in fluorescein angiography.
abstract: New developments in fluorescein angiography concern the apparatus employed, technique and the photographic laboratory. A wide-angle retinograph has been developed which enables us to photograph the periphery of the fundus. Television, with a very sensitive camera, permits us to obtain very well defined dynamic views with pictures at the rate of 25 per second. This technique enables us to resolve some new problems. The use of television produces stronger fluorescence than that achieved by ordinary photography and allows us to choose the best pictures relating to a clinical problem.
