Fig. 2. Sections of the rabbit's retina. Hematoxylin-eosin. Objective (oil) X 50. 

 Top: Control retina which is detached from pigment epithelium. 2, layers of the 

 rods and cones with the outer and inner segments: 4, outer nuclear layer comprising 

 the nuclear regions of the visual cells: 6, inner nuclear layer, the nuclei of bipolar 

 cells (round) and of the Miiller cells (oval, dark) ; 8, layer of the ganglion 

 cells. Bottom: Section from an equivalent retinal area 10 days after x-irradiation. 

 1, pigment epithelium, which after the disappearance of the visual cells makes 

 contact with the remaining retina. The space between pigment epithelium and inner 

 nuclear layer is invaded by Miiller cells.
