Histological Studies on the Retina of the Falcon "S Eye Ball (Circus Cyaneus C.) Under Light and Electron Microscopy

Abstract

The histological study showed that the retina of falcon"s eyeball was thin at the periphery and ranges between 0.6-0.8 μ but it was thick at center 1.68-2.64 μ. The retina consists from ten layers: pigmented epithelium, rods and cons layer, external nuclear layer, external plexiform layer, internal nuclear layer, internal plexiform layer, Gangilionic cells layer, neurofibres layer and internal limiting membrane layer. The ultra-structural study stated that the rods and cons layers contained single rods with single and double cons. The retina characterized by lacking of the oil droplets in the internal segments of rods with narrow external plexiform layer in order to form network connecting rods and cones, horizontal cells, bipolar cells and Muller's cells.
