Vitreous detachment
Vitreous Detachment
Vitreous Detachment (pronunciation: vih-tree-us deh-tach-ment) is a condition in which the vitreous humor, a gel-like substance that fills the eye, separates from the retina. This is a common occurrence as people age, but it can also occur as a result of injury or disease.
Etymology
The term "vitreous" comes from the Latin word "vitreus", meaning "glassy" or "transparent", referring to the clear, gel-like substance that fills the eye. "Detachment" comes from the French word "détacher", meaning "to separate" or "to detach", referring to the separation of the vitreous humor from the retina.
Symptoms
Symptoms of vitreous detachment may include floaters, flashes of light, or a shadow or curtain appearing across the field of vision. These symptoms can occur suddenly or gradually over time.
Causes
Vitreous detachment is most commonly caused by age-related changes in the vitreous humor. As people age, the vitreous humor can shrink and pull away from the retina. Other causes can include eye injury, high myopia, or inflammatory eye diseases.
Treatment
Treatment for vitreous detachment is typically not necessary unless it leads to a retinal detachment. In this case, surgery may be required to reattach the retina and prevent vision loss.
