Choose the correct statement w.r.t. aqueous humour
Solution:
Aqueous humour is a clear, watery fluid that fills the anterior chamber of the eye (the space between the cornea and the lens). It is continuously produced by the ciliary body and is responsible for nourishing the cornea and lens, as well as maintaining intraocular pressure. This fluid is continuously drained from the eye into the venous blood circulation, primarily through the canal of Schlemm. Option (1) describes the vitreous humour, which fills the space between the lens and the retina. Option (2) also describes the vitreous humour, which is a transparent, semi-solid, gelatinous substance. Option (4) is incorrect as the aqueous humour is in the anterior segment, while the choroid is part of the posterior vascular layer of the eye.
