  2. Posterior vitreous detachment - Wikipedia

    en.wikipedia.org/wiki/Posterior_vitreous_detachment

    A posterior vitreous detachment (PVD) is a condition of the eye in which the vitreous membrane separates from the retina. [1] It refers to the separation of the posterior hyaloid membrane from the retina anywhere posterior to the vitreous base (a 3–4 mm wide attachment to the ora serrata ).

  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. Vitreous body - Wikipedia

    en.wikipedia.org/wiki/Vitreous_body

    The vitreous body at birth is homogenous with a finely striated pattern. With early aging the vitreous develops narrow transvitreal "channels". The cortex is denser than the centre with development. From adolescence, vitreous tracts form from anterior to posterior. These vitreous tracts are fine sheet-like condensations of vitreous. Named tracts

  5. Retinal tuft - Wikipedia

    en.wikipedia.org/wiki/Retinal_tuft

    Retinal tufts can classified into three subtypes: cystic, non-cystic, and zonular traction retinal tufts. [5] Cystic tufts are usually larger than 0.1mm in length. [5] Non-cystic retinal tufts are usually shorter, less than 0.1mm in length and are often clustered together in a series of projections within the vitreous base. [5]

  6. 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]

  7. Photopsia - Wikipedia

    en.wikipedia.org/wiki/Photopsia

    Peripheral (posterior) vitreous detachment occurs when the gel around the eye separates from the retina. This can naturally occur with age. However, if it occurs too rapidly, it can cause photopsia which manifests in flashes and floaters in the vision. Typically, the flashes and floaters go away in a few months.

  8. 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 ...

  9. Floater - Wikipedia

    en.wikipedia.org/wiki/Floater

    Laser vitreolysis is a possible treatment option for the removal of vitreous strands and opacities (floaters). In this procedure an ophthalmic laser (usually a yttrium aluminium garnet (YAG) laser) applies a series of nanosecond pulses of low-energy laser light to evaporate the vitreous opacities and to sever the vitreous strands. When ...
