Bleaching of the isolated retina.

Our theory for photoreceptor bleaching (Leibovic and Kurtz, 1975; Leibovic, 1975) is extended to the isolated retina, a preparation often used in experimental research. Experimental data are presented which demonstrate good agreement with the theory, and it is shown that bleaching history can affect the final result. Since our theory includes a lumped intermediate state of bleaching, it is superior to theories which only consider end products. On the other hand, our theory is more tractable than others which specify several intermediates.
