title: Ultrastructure of the pigment epithelium and the photoreceptors in the retina of the horse.
abstract: An electron microscopic description was given of the pigment epithelium and the photoreceptors of the horse retina. Duplicity (rods-cones) of the horse retina was proven histologically; the retina was classified as an "E" retina, which indicates predominance of the rod system.
