  2. Blood–ocular barrier - Wikipedia

    en.wikipedia.org/wiki/Blood–ocular_barrier

    The blood–ocular barrier is a barrier created by endothelium of capillaries of the retina and iris, ciliary epithelium and retinal pigment epithelium. [1] It is a physical barrier between the local blood vessels and most parts of the eye itself, and stops many substances including drugs from traveling across it. [2]

  3. Vitreous body - Wikipedia

    en.wikipedia.org/wiki/Vitreous_body

    The vitreous humor is a transparent, colorless, gelatinous mass that fills the space in the eye between the lens and the retina.It is surrounded by a layer of collagen called the vitreous membrane (or hyaloid membrane or vitreous cortex) separating it from the rest of the eye.

  4. Ciliary body - Wikipedia

    en.wikipedia.org/wiki/Ciliary_body

    Folds on the inner ciliary epithelium are called ciliary processes, and these secrete aqueous humor into the posterior chamber. The aqueous humor then flows through the pupil into the anterior chamber. [3] The ciliary body is attached to the lens by connective tissue called the Zonule of Zinn (fibers of Zinn).

  5. Human eye - Wikipedia

    en.wikipedia.org/wiki/Human_eye

    The spaces of the eye are filled with the aqueous humour anteriorly, between the cornea and lens, and the vitreous body, a jelly-like substance, behind the lens, filling the entire posterior cavity. The aqueous humour is a clear watery fluid that is contained in two areas: the anterior chamber between the cornea and the iris, and the posterior ...

  6. Aqueous humour - Wikipedia

    en.wikipedia.org/wiki/Aqueous_humour

    The internal wall of the canal is very delicate and allows the fluid to filter due to the high pressure of the fluid within the eye. [7] The secondary route is the uveoscleral drainage , and is independent of the intraocular pressure, the aqueous flows through here, but to a lesser extent than through the trabecular meshwork (approx. 10% of the ...

  7. Vitreous hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Vitreous_hemorrhage

    A tear in the retina can allow fluids from the eye to leak in behind the retina, which causes retinal detachment. When this occurs, blood from the retinal blood vessels can bleed into the vitreous. [4] Retinal tear accounts for 11.4–44% of vitreous hemorrhage cases. [1]

  9. Vitreous chamber - Wikipedia

    en.wikipedia.org/wiki/Vitreous_chamber

    The vitreous fluid, along with supporting the lens, also functions in maintaining the shape of the entire vitreous chamber and posterior cavity. It is imperative that the eye remains the proper shape to ensure that the light passing through the lens and the fluid can focus properly on the retina. The composition of the fluid is 99% water and ...
