What are the layers of the cornea from inside out?

The correct arrangement of the layers of the cornea from the inside out begins with the endothelium, which is the innermost layer of the cornea responsible for maintaining corneal dehydration and transparency. Next is Descemet's membrane, a thin layer that acts as a protective barrier between the stroma and the endothelium.

Moving outward, the stroma is the thickest layer of the cornea, providing structural strength and resilience due to its collagen fibers. Bowman's layer follows the stroma and serves a protective function, although it is not as thick or as substantial as the stroma. Finally, the outermost layer is the epithelium, which consists of several layers of cells that provide an essential barrier against the environment, helping to prevent infection and desiccation.

Understanding the correct order of the corneal layers is crucial for recognizing how they function together to maintain the health and transparency of the cornea, which is vital for proper vision.
