Abstract:

The present study was carried out on cornea of the Japanese quail. The cornea was the transparent, non-vascular structure and slightly curved front part of the eye and it covers the anterior chamber, iris and pupil in back side. The cornea was composed of anterior epithelium, bowman’s membrane, substantia propria, descemet’s membrane and posterior epithelium. The anterior epithelium was lined by non-keratinized stratified squamous epithelium of five to six layers of epithelial cells. The bowman’s membrane was observed as an acellular, transparent homogenous layer with numerous collagen fibres, which ran parallel to the corneal surface and placed beneath the anterior epithelium. The thickness of the substantia propria was found to be more than the other layers of the cornea and hence formed the greater part of the cornea. The posterior epithelium which lined the inner side of the descemet’s membrane consisted of a single layer of cuboidal cells. The thickness of the cornea ranged from 110.20±0.209µm to 156.39 ±1.244µm on the right eye ball and 109.70±0.182µm to 156.26±1.199µm on the left eye ball in two week-old to fourteen week-old Japanese quail.
