Aqueous humour
|
|
The aqueous humour is secreted into the posterior chamber by the ciliary body and flows through the narrow cleft between the front of the lens and the back of the iris, to escape through the pupil into the anterior chamber, and then to drain out of the eye via the trabecular meshwork into the aqueous veins and eventually into the veins of the orbit.
Glaucoma is a condition characterised by increased intraocular pressure (pressure within the eye), usually caused by increased resistance to outflow of aqueous humour through an abnormal trabecular meshwork, or to obliteration of the meshwork caused by injury or disease of the iris. Uncontrolled glaucoma will lead to visual field loss and ultimately blindness.
