Wide field fluorescein angiography by use of contact lens.

A system has been developed to obtain fluorescein angiographs with a field measuring to 90 degrees. This involves a contact lens and a new fundus camera with a basic field of 60 degrees. The contact lens, however, can be used with any fundus camera and will result in an increase in the area of the photographs of over 2X. There are numerous clinical applications for high resolution, high contrast, wide field fluorescein angiography.
