Aqueous humor is formed by three mechanisms: diffusion, ultrafiltration, and active secretion by the non-pigmented ciliary epithelium water reacts chemically . The eye achieves this by the production, accumulation and circulation of a clear fluid called aqueous humor (ah) ah is produced by selective transfer of solutes .

Aqueous humour (ah) is a transparent fluid contained in the anterior and poste- rior chambers of the eye and is formed by the ciliary epithelium. Aqueous humor formation • aqueous humor is produced from pars plicata along the crests of the ciliary processes lens • aqueous humor is. Aqueous humour was once thought to be a dialysate of plasma, or to be secreted as such by the ciliary body in a manner analogous to secretion of saliva.
