  2. Vitreous body - Wikipedia

    en.wikipedia.org/wiki/Vitreous_body

    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.

  3. Vitreous membrane - Wikipedia

    en.wikipedia.org/wiki/Vitreous_membrane

    The vitreous membrane (or hyaloid membrane or vitreous cortex) is a layer of collagen separating the vitreous humour from the rest of the eye. At least two parts have been identified anatomically. The posterior hyaloid membrane separates the rear of the vitreous from the retina. It is a false anatomical membrane. [1]

  4. Hyaloid canal - Wikipedia

    en.wikipedia.org/wiki/Hyaloid_canal

    Schematic diagram of the human eye. The hyaloid canal (Cloquet's canal and Stilling's canal [1]) is a small transparent canal running through the vitreous body from the optic nerve disc (at the punctum caecum) to the lens. It is formed by an invagination of the hyaloid membrane, which encloses the vitreous body.

  5. Synchysis scintillans - Wikipedia

    en.wikipedia.org/wiki/Synchysis_scintillans

    The vitreous liquifies in a process known as syneresis. Synchysis scintillans appears as small white floaters that freely move in the posterior part of the eye, giving a snow globe effect. It is most commonly seen in eyes that have suffered from a degenerative disease and are end-stage. [1] The condition is seen rarely.

  6. 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 ...

  7. Posterior segment of eyeball - Wikipedia

    en.wikipedia.org/wiki/Posterior_segment_of_eyeball

    The posterior segment or posterior cavity [1] is the back two-thirds of the eye that includes the anterior hyaloid membrane and all of the optical structures behind it: the vitreous humor, retina, choroid, and optic nerve. [2]

  8. Human eye - Wikipedia

    en.wikipedia.org/wiki/Human_eye

    The human eye is a sensory organ in the visual system that reacts to visible light allowing eyesight. Other functions include maintaining the circadian rhythm, and keeping balance. Arizona Eye Model. "A" is accommodation in diopters. The eye can be considered as a living optical device.

  9. Floater - Wikipedia

    en.wikipedia.org/wiki/Floater

    The vitreous humour, or vitreous body, is a jelly-like, transparent substance that fills the majority of the eye. It lies within the vitreous chamber behind the lens, and is one of the four optical components of the eye. [8] Thus, floaters follow the rapid motions of the eye, while drifting slowly within the pocket of liquid. [9]
