aqueous humor  definition
humour, aqueous. Clear, colourless fluid that fills the anterior and posterior chambers of the eye. It is a carrier of nutrients for the lens and to a larger extent the cornea, especially of glucose and essential amino acids. It contributes to the maintenance of the intraocular pressure. aqueous humor the fluid produced in the eye and filling the spaces (anterior chamber and posterior chamber) in front of the lens and its attachments. It diffuses out of the eye into the blood and is regarded as the lymph of the eye, although its composition is different from that of the lymph in the rest of the body. Aqueous humor: In medicine, humor refers to a fluid (or semifluid) substance. Thus, the aqueous humor is the fluid normally present in the front and rear chambers of the eye. It is a clear, watery fluid that flows between and nourishes the lens and the cornea; it is secreted by the ciliary processes.

This theory (which was variously called the humoral theory, humoralism, and humorism) was devised well before Hippocrates (c.460-c.375 BC). It was not definitively demolished until Rudolf Virchow published his formative book, Cellularpathologie, in 1858 that laid out the cellular basis of pathology. Present day pathology rests on a cellular and molecular foundation. The humors have been dispelled, except for the aqueous humor. It is formed in the ciliary processes, flows into the posterior chamber, then through the pupil into the anterior chamber and leaves the eye through the trabecular meshwork passing to the canal of Schlemm and then to veins in the intrascleral venous plexus (Fig. How to pronounce aqueous humour in British English. us.

H3). A small amount (10% to 15%) also flows out of the eye via the uveoscleral pathway. The aqueous in the anterior chamber is a component of the optical system of the eye. It has an index of refraction of 1.336, slightly lower than that of the cornea, so that the cornea/aqueous surface acts as a diverging lens of low power. aqueous humor with a protein concentration approaching that of plasma; seen in inflammation or other disruption of the blood-aqueous barrier. aqueous suspension. a mixture of insoluble particles in water. The answer may seem obvious, but the use of this word can lead to confusion. In the UK and Ireland the word traditionally meant the number 1,000,000,000,000 (a million millions), which is called a trillion in the United States. A billion in the United States is considerably.
