  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 typically painless, with symptoms often starting in the peripheral vision. [3] [9] [10] Symptoms of retinal detachment, as well as posterior vitreous detachment (which often, but not always, precedes it), may include: [3] [4] [9] [10] [12] Floaters suddenly appearing in the field of vision or a sudden increase in the ...

  4. Vitreous hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Vitreous_hemorrhage

    As one gets older, pockets of fluid can develop in the vitreous. When these pockets develop near the back of the eye, the vitreous can pull away from the retina and possibly tear it. [2] Posterior vitreous detachment accounts for 3.7–11.7% of vitreous hemorrhage cases. [1]

  5. Epiretinal membrane - Wikipedia

    en.wikipedia.org/wiki/Epiretinal_membrane

    Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes.Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).

  6. Human eye - Wikipedia

    en.wikipedia.org/wiki/Human_eye

    The vitreous gel undergoes liquefaction (posterior vitreous detachment or PVD) and its opacities — visible as floaters — gradually increase in number. Eye care professionals , including ophthalmologists and optometrists , are involved in the treatment and management of ocular and vision disorders.

  7. Intraocular hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Intraocular_hemorrhage

    Vitreous hemorrhage can be caused by proliferative diabetic retinopathy, vitreous detachment with or without retinal breaks, and trauma. Less common causes include vascular occlusive disease , retinal arterial macroaneurysm , hemoglobinopathy , age-related macular degeneration , and intraocular tumors .

  8. 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]

  9. 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.
