They are each about 1.5-2.5 μm in thickness. The anterior lamellae interweave more than posterior lamellae. The fibrils of each lamella are parallel with one another, but at different angles to those of adjacent lamellae. The lamellae are produced by keratocytes (corneal connective tissue cells), which occupy about 10% of the substantia propria.
Corneal stroma (also substantia propria): a thick, transparent middle layer, consisting of regularly arranged collagen fibers along with sparsely distributed interconnected keratocytes, which are the cells for general repair and maintenance. [10] They are parallel and are superimposed like book pages.
In the anatomy of the eye, the conjunctiva (pl.: conjunctivae) is a thin mucous membrane that lines the inside of the eyelids and covers the sclera (the white of the eye). [1] It is composed of non-keratinized, stratified squamous epithelium with goblet cells , stratified columnar epithelium and stratified cuboidal epithelium (depending on the ...
Oblique fibers in the anterior layer of the substantia propria; Lamellae, the fibers of which are cut across, producing a dotted appearance; Corneal corpuscles appearing fusiform in section; Lamellae, the fibers of which are cut longitudinally; Transition to the sclera, with more distinct fibrillation, and surmounted by a thicker epithelium

The conjunctiva is a tissue that lines the inside of the eyelids and covers the sclera. It is composed of unkeratinized, stratified squamous epithelium with goblet cells, and stratified columnar epithelium. The conjunctiva is basically transparent, and the white colour we see is actually sclera.
In addition, the substantia propria of the cornea breaks down and liquefies, resulting in keratomalacia. [1] The resulting cornea becomes totally opaque, which is one of the most common reasons for blindness around the world [citation needed], particularly in developing countries.
The corneal limbus (Latin: corneal border) is the border between the cornea and the sclera (the white of the eye).It contains limbal stem cells in its palisades of Vogt.It may be affected by cancer or aniridia (a developmental problem), among other issues.
