title: [Limited diffusion of dye between choroid and retina during animal experiments after injection of fluorescein and rhodamin (author's transl)].
abstract: For contributing to the question of an existence of a diffusion of the unbound part of the fluorescein between choroid and retina in fluorescein angiography, on pigmented rats, after intravenous injection of Fluorescein sodium and Rhodamine B respectively, comparing observations were effectuated. Rhodamine B in its unbound form showed a distinct diffusion between choroid and retina and coloured all retinal layers in the late phases whereas in the case of the Fluorescein sodium, only a poor diffusion was observable. The similar spectral bands of the primary and secondary fluorescences render difficult the observation of the behaviour of the fluorescein dye.
