Abstract :

The present study was carried out on eye ball of the adult Marwari goat (Capra hircus) irrespective of the sex. The retina was the innermost layer of the tunic of the eye ball. Retina had twoportion, one was sensory (pars optic retinae) and another one was nonsensory. Thesensory part of the retina was composed of ten layer. The retinal pigmented epithelium (RPE) was the outermost single layer of flat cellsof the retina. The cells of the RPE were pigmented except the area where the tapetum fiosum was present. The next layer was layer of rod and cone cells which comprised of only outer part of the rods and cones i.e. outer and inner segment. Outer limiting memane separated the layer of rods and cones from the outer nuclear layer.The outer nuclear layer was composed mainly of nuclei of rods and cones.The outer plexiform layer was a thin layer that separated the outer nuclear layer from the inner nuclear layer. The inner nuclear layer comprised of the nuclei of the horizontal cells, bipolar cells, amacrine cells and Mullerís cells.The inner plexiform layer was comprised of the bipolar and amacrine cell axon and dendrites of the ganglion cells.The ganglion cell layer was the innermost cell layer of the retina.The nerve fiber layer formed by the axon of ganglion cell. The internal limiting memane was the innermost layer of the retina.Thickness of the retina found to be varied from region to region, it was thickest at optic disc and tapering towards the ora ciliaris retinae.
