Aqueous Humour - English Definition & Meaning

Definition

Aqueous humour (also spelled aqueous humor) is the clear, watery fluid that fills the anterior chamber of the eye, the space between the cornea and the lens. This fluid provides nutrients to the cornea and the lens, neither of which have their own blood supply. Imagine it as the eye's personal delivery service, ensuring vital components receive what they need. Additionally, it maintains the intraocular pressure, which is critical for maintaining the shape of the eyeball. Produced by the ciliary body, it circulates and drains through the trabecular meshwork. Imbalance in production or drainage can lead to glaucoma. Its balanced composition and pressure are essential for optimal vision.

Etymology

The term 'aqueous humour' comes from Latin and Old French. 'Aqueous' means 'watery' or 'resembling water,' describing the fluid's consistency. 'Humour' (originally spelled with a 'u' in both British and older American English) refers to a bodily fluid, stemming from the ancient Greek theory of humors. The French term 'humeur' also contributes to this understanding. The term 'aqueous humour' therefore translates to 'watery bodily fluid'. It's simply a British English variant of 'aqueous humor'.
