[Angiography by the oral route using enteric-coated capsules]

We have performed Retinal Fluorescein Angiograms in three groups of patients who had been previously administered, respectively: intravenous sodium fluorescein, hard gelatin-coated fluorescein oral capsules, and enteric-coated fluorescein capsules. In all groups, we carried out a curve of the dye plasma levels. We concluded that the enteric-coated fluorescein capsules provide effective dye plasma levels for the performance of the angiogram between 40 and 60 minutes later, thus obtaining great sharpness and quality retinal images, much better than those attained with the hard gelatin-coated fluorescein capsules.
