Multiple optic fiber patterns in the catfish retina.
The retinas of certain catfish contain multiple optic discs. This report describes the patterns of optic nerve fibers and optic discs as seen in silver-stained flat mounts, in 11 different families of catfish. As many as 50 optic discs may exist in a single retina, in paired and unpaired combinations, and in slit and ring-like arrays.
