Which corneal layer forms the inner surface facing the anterior chamber?

Which corneal layer forms the inner surface facing the anterior chamber?

• A. Epithelium
• B. Bowman's membrane
• C. Stroma
• D. Endothelium

Answer: (D)

The cornea has layers from front to back: epithelium, Bowman's membrane, stroma, Descemet's membrane, and endothelium. The inner surface that faces the anterior chamber is formed by the endothelium. This single layer of cells lines the posterior corneal surface and is essential for keeping corneal hydration in check, pumping fluid out of the stroma into the anterior chamber to maintain transparency. The other layers are located on the front side or between the front and this inner surface, so they do not form the inner boundary facing the aqueous in the chamber.
