These substances are called the vitreous humor and aqueous humor.

The primary eye structures connected to aqueous humor dynamics are the ciliary body (the site of aqueous humor production), and the trabecular meshwork and the uveoscleral path (the principal places of aqueous humor outflow). Aqueous humour, optically clear, slightly alkaline liquid that occupies the anterior and posterior chambers of the eye (the space in front of the iris and lens and the ringlike space encircling the lens). Production Function of Aqueous Humor. Gel-like fluids inside the eye help it maintain its shape, which plays an important role in overall eye health. This fluid nourishes the cornea and the lens, and gives the eye its shape.

The aqueous humour is a thin, transparent fluid similar to plasma. Aqueous humor is an optically clear, slightly alkaline ocular fluid that is continuously formed (~ 2.5 μL/min in humans) from plasma by epithelial cells of ciliary body [34].Three different processes – diffusion, ultrafiltration and active secretion – contribute to the chemical composition and formation of aqueous humor. It’s made up of 99.9% water ­­– the other 0.1% consists of sugars, vitamins, proteins and other nutrients.
