see blood-aqueous barrier.

aqueous flare

turbidity of the aqueous humor caused by increased protein levels and cells.

aqueous humor

the fluid produced by the ciliary process in the eye and occupying the anterior and posterior chambers. It provides nourishment for the lens and cornea and maintains the ocular pressure, and hence the optical integrity of the eyeball. Disturbance of its drainage through the corneoiridial angle can induce glaucoma and other disorders.

aqueous misdirection

see ciliovitreolenticular block.

aqueous paracentesis

see aqueocentesis.

plasmoid aqueous

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.

flare, aqueous

Scattering of light seen when a slit-lamp beam is directed, obliquely to the plane of the iris, into the anterior chamber. It occurs as a result of increased protein content, and usually inflammatory cells, in the aqueous humour. Visual impairment depends on the intensity of the flare. It is a sign of intraocular inflammation. See Tyndall effect; iritis; uveitis.
