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.
ocular humor either of the humors of the eye—aqueous or vitreous.
vitreous humor the fluid portion of the vitreous body; often used to designate the entire vitreous body.

a·que·ous hu·mor

[TA]
the watery fluid that fills the anterior and posterior chambers of the eye. It is secreted by the ciliary processes within the posterior chambers and passes through the the pupil into the anterior chamber where it filters through the trabecular meshwork and is reabsorbed into the venous system at the iridocorneal angle by way of the sinus venosus of the sclera;
