Abstract— –Visible light changes IR light scatter through a toad retina. This signal presents three components: at low light intensity (100–400 bleached rhodopsins/rod) an early decrease in IR light scatter, of small amplitude, with time to peak of 1–6 s; at intermediate light intensity (1200‐16 000 bleached rhodopsins/rod) a slow increase in IR light scatter, with time to peak of 10–30 s; at high light intensity (50 000–160 000 bleached rhodopsins/rod) a last increase in IR light scatter, with time to peak of 1 min. Light sensitivity, amplitude and time to peak of the last two components are increased by inhibitors (3‐isobutyl‐l‐methyl‐xanthine and papaverine) of the cyclic 3'5′guanosine monophosphate phosphodiesterase.
