Color angiography and angioscopy.

The authors present the results of their color fluorescein angiographies carried out with a pocket retinograph equipped with new interferential filters. After the graphic examination, they propose to use these same filters mounted on different instruments for binocular and monocular angioscopy. Their results show that retinal vessels are translucid and that their color changes according to their background. The authors termed this change 'versicolored effect'. Moreover, color angiography with these new filters eliminates pseudofluorescence and adds to the fluoroscopic examination an element of analytic perfection, thus giving a new opening to differential diagnosis in endo-ocular diseases.
