Histomorphometrical and histochemical postnatal development of cornea in indigenous rabbits

The present study aims to clarify corneal development via analyzing of the histomorphologic and some histochemical parameters in local rabbits. Samples were collected from 25 Rabbits divided into five different age groups at 1, 10, 15, 30, 40 postnatal day (PND), then samples sectioned, processed, stained with Hematoxylin eosin stain Masson’s trichrome stain. Some sections further periodic acid Schiff (PAS) toluidine blue (TB) for evaluation. Measurements layers performed morphometric comparison among groups. finding revealed thickening epithelium, stroma, endothelium progressively decrease layer’s cellular density concurrently alteration epithelium cell’s type. late appearance bowman’s Descemet’s membranes after eyelid opening which responded strongly PAS technique while stroma became metachromatic In conclusion, cornea showed highly active histological differentiation before opening.
