Effects of X-radiation on the retina of the albino rabbit as viewed with the transmission electron microscope.

The eyes of albino rabbits were exposed in vivo to 7,000 rad of X-radiation. The retinae were dissected and examined with a transmission electron microscope 24 and 72 h following irradiation. Damage after 24 h was minimal, but after 72 h it was very pronounced. In both cases the damage was restricted to the photoreceptors.
