The vitreous fluid is not present at birth (the eye being filled with only the gel-like vitreous body), but found after age 4-5, and increases in size thereafter. [1] Produced by cells in the non-pigmented portion of the ciliary body, the vitreous humour is derived from embryonic mesenchyme cells, which degenerate after birth. [1]
The ciliary body is a ring-shaped thickening of tissue inside the eye that divides the posterior chamber from the vitreous body. It contains the ciliary muscle, vessels, and fibrous connective tissue. Folds on the inner ciliary epithelium are called ciliary processes, and these secrete aqueous humor into the posterior chamber. The aqueous humor ...

Hyalocytes, also known as vitreous cells, are cells of the vitreous body, which is the clear gel that fills the space between the lens and the retina of the eye. Hyalocytes occur in the peripheral part of the vitreous body, and may produce hyaluronic acid and collagen fibrils , [ 1 ] [ 2 ] Hyalocytes are star-shaped (stellate) cells with oval ...

the posterior chamber between the iris and the front face of the vitreous. [2] Aqueous humour fills these spaces within the anterior segment and provides nutrients to the surrounding structures. Some ophthalmologists and optometrists specialize in the treatment and management of anterior segment disorders and diseases. [3]
The pecten is believed to both nourish the retina and control the pH of the vitreous body. [2] High levels of alkaline phosphatase activity in the pecten oculi have been linked to the transport of nutrient molecules from the highly vascularized choroid into vitreous and retinal cells, thus nourishing the eye.
