  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. Retinal detachment - Wikipedia

    en.wikipedia.org/wiki/Retinal_detachment

    Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4] Retinal detachment is a medical emergency that requires surgery. [2] [3]

  4. Vitreomacular traction syndrome - Wikipedia

    en.wikipedia.org/wiki/Vitreomacular_traction...

    Vitreomacular traction syndrome (VTS) is a medical condition in the eye that is the result of tractional forces (pulling) being placed on the retina. [1] [2] VTS is common in people who have an incomplete posterior vitreous detachment, a type of retinal detachment at the periphery of the retina. [1]

  5. Proliferative vitreoretinopathy - Wikipedia

    en.wikipedia.org/wiki/Proliferative_vitreo...

    During rhegmatogenous retinal detachment, fluid from the vitreous humor enters a retinal hole. The mechanisms by which retinal holes or tears form are not fully understood yet. The accumulation of fluid in the subretinal space and the tractional force of the vitreous on the retina result in rhegmatogenous retinal detachment.

  6. Vitreous body - Wikipedia

    en.wikipedia.org/wiki/Vitreous_body

    If the vitreous pulls away from the retina, it is known as a vitreous detachment. As the human body ages, the vitreous often liquefies and may collapse. This is more likely to occur, and occurs much earlier, in eyes that are nearsighted (myopia). It can also occur after injuries to the eye or inflammation in the eye .

  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]

  8. 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.

  9. Vitrectomy - Wikipedia

    en.wikipedia.org/wiki/Vitrectomy

    Retinal detachment – a blinding condition where the lining of the eye peels loose and floats freely within the interior of the eye. Steps to reattach the retina may include vitrectomy to clear the inner jelly, scleral buckling to create a support for the reattached retina, membranectomy to remove scar tissue, injection of dense liquids to ...
