Studies on the distribution of phosphorylase in eyes of the rabbit and the squirrel monkey

Summary Detailed studies on phosphorylase localization in various components of the eyeball of rabbit and squirrel monkey have been made. Corneal epithelium, endothelium, and stromal cells, extrinsic and intrinsic muscles of the eyeball, ciliary process, endothelial cells of the anterior chamber angle, vitreal cells, lens epithelium, inner segment of cones; plexiform layer, ganglion cell layer, internal and external limiting membrane and Muller cells show high phosphorylase activity. Surprisingly, we observed phosphorylase activity inside the nucleus in the posterior 2 to 3 layers of corneal epithelium. The significance of phosphorylase localization in relation to glycogen distribution in various components of the eyeball and their energy requirements is stressed.
