Which of the following is NOT one of the 3 main methods of aqueous production?

The method of aqueous production that is not considered one of the three main mechanisms is corneoscleral production. Aqueous humor in the eye is primarily produced through three established processes: diffusion, ultrafiltration, and active secretion.

Diffusion refers to the passive movement of solutes across a permeable membrane, relying on concentration gradients. This process contributes minimally to aqueous production but is essential for maintaining the concentration of various substances within the aqueous humor.

Ultrafiltration involves the passage of water and solutes through a membrane due to hydrostatic pressure, and this method plays a significant role in regulating the aqueous humor volume in the anterior chamber of the eye.

Active secretion is the most significant method of aqueous production, where the ciliary processes of the eye actively transport ions (such as sodium) into the aqueous humor, which then draws water into the anterior chamber osmotically.

Corneoscleral production is not recognized as a primary mechanism for aqueous humor production. Although the cornea and sclera have roles in the overall physiology of the eye, they do not directly produce aqueous humor in the manner described by the other three methods. This understanding highlights the importance of the ciliary body as the crucial source of aqueous humor and clarifies the distinctions between
