Structure of Cornea

Cornea is anatomically formed by 5 strata:

-Epithelium stratum:       

Regeneration ability quick 5-6 rowed, it is non-keratinized multi-layered flat epithelium. Frontal face is covered by lacrima. Sensory nerves going along Bowman’s membrane level end among epithelium cells. It is tightly attached with basal membrane to Bowman’s membrane below.

-Bowman Layer:

It is a condensed frontal part of stroma lamella. It is not renewed after a physical injury, opacities (scar tissue) causing visual disorder grows on its place.

-Stroma:

It generates % 90 of cornea thickness. Collagen fibers forming stroma have a uniform structure. Without intersecting to each other, it cruises from limbus to limbus. They are located in the inclusion body composed of mucosaccharide. Stroma is poor from cell. These cells which are called keratocyte turn into fibroblast when injuries occur and they provide wound reparation.

-Descemet’s Membrane:

It is a basal membrane of endothelium cells. It has extra elasticity compared to other strata of cornea. It is not attached to stroma. It can easily be peeled off.

-Endothelial:

It is comprised of single row hexagonal cells. They are not reproduced by mitosis.
