[Microspectrophotometric research on the rhodopsin and carotenoid content of the retinal visual cells of hens maintained on a vitamin A-deficient diet].
Using microspectrophotometry, a study was made of the retina of adult hens, that had been kept on a diet for 6.5 months with deficiency of vitamin A. It has been shown that despite an expressed drop of quantity of vitamin A in the liver, in the external segments of the retina rods in A-avitaminosis hens, the concentration of rhodopsin remains normal.
