    The most common cause found in adults is diabetic retinopathy. Abnormal blood vessels can form in the back of the eye of a person with diabetes. These new blood vessels are weaker and prone to breaking and causing hemorrhage. [2] Diabetic retinopathy accounts for 31.5–54% of all cases of vitreous hemorrhage in adults in the United States. [1]

    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. [10]

  4. Vitrectomy - Wikipedia

    en.wikipedia.org/wiki/Vitrectomy

    After vitrectomy to remove the vitreous gel, membranectomy is undertaken to peel away the tissue. Diabetic retinopathy – may damage sight by either a non-proliferative or proliferative retinopathy. The proliferative type is characterized by formation of new unhealthy, freely bleeding blood vessels within the eye (called vitreal hemorrhage ...

    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).

    Retinal hemorrhage (UK English: retinal haemorrhage) is a disorder of the eye in which bleeding occurs in the retina, the light sensitive tissue, located on the back wall of the eye. [1] There are photoreceptor cells in the retina called rods and cones , which transduce light energy into nerve signals that can be processed by the brain to form ...

  7. Sickle cell retinopathy - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_retinopathy

    Central retinal artery occlusion is a known feature of non-proliferative sickle cell retinopathy that has a low incidence in patients with non proliferative sickle cell retinopathy. [5] Optic nerve sign is represented by dilated capillaries that can be visualized in the nerve using fluorescein angiography. Visual acuity often remains unchanged ...

  8. Terson syndrome - Wikipedia

    en.wikipedia.org/wiki/Terson_syndrome

    Diabetic retinopathy: This condition can induce confusion, particularly in diabetic patients, by causing retinal and vitreous hemorrhages that resemble those in Terson's syndrome. Diabetic retinopathy might be the first thing considered in the absence of a complete neurological history.

    Diabetic retinopathy (also known as diabetic eye disease) is a medical condition in which damage occurs to the retina due to diabetes.It is a leading cause of blindness in developed countries and one of the lead causes of sight loss in the world, even though there are many new therapies and improved treatments for helping people live with diabetes.
