[Scanniing electron-microscopic study of vascular distribution in the choriocapillaris and lamina vasculosa of the rat eye]

Abstract

The choriocapillaris and lamina vasculosa of the rat eye were injected with methylmethacrylate and their vascular replicas were studied in the scanning electron microscope. There was not outstanding lobular distribution of vessels in the rat choriocapillaris. Their capillaries form a continuous anastomosed network that covers 85-95% of the surface of pigment epithelium. The terminal arteries ramify into many precapillary vessels that present a lacelike network. Advantages and disadvantages of vascular plastic replicas are discussed.
