What are the five layers of the cornea from anterior to posterior?

The five layers of the cornea from anterior to posterior are accurately listed as epithelium, Bowman's layer, stroma, Descemet membrane, and endothelium.

The epithelium is the outermost layer, providing a protective barrier against environmental factors. Beneath it lies Bowman's layer, a tough sublayer that adds structural integrity. The stroma is the thickest layer and consists mostly of collagen fibers that maintain corneal shape and transparency. Descemet membrane is a thin but strong layer that serves as a basement membrane for the corneal endothelium, which is the innermost layer responsible for maintaining corneal hydration and clarity by regulating fluid transport.

The other options contain incorrect information regarding the layers of the cornea. For instance, references to the retina or ciliary body, which are parts of the eye but not layers of the cornea, highlight misconceptions regarding eye anatomy. Understanding the correct layering is crucial for comprehending corneal health and addressing various ocular conditions.
