Fig. 8 A. Immunofluorescence labeling of foveal cones with anti-red/green cone opsin (red). B. Immunofluorescence labeling of foveal cones with anti-blue cone opsin (red). The majority of cones in the fovea contain red/green opsin. C. Immunofluorescence labeling of fovea with antibody to rod outer segment (red) showing lack of rods in the fovea (*). Other cell nuclei in the outer nuclear layer and inner nuclear layer are stained with DAPI (blue). (Courtesy of Scheie Eye Institute)
