Separation of the peripheral vitreous humor from the retina.

vitreous detachment

Separation of the rear part of the VITREOUS BODY from the retina as a result of the natural shrinkage that occurs in the elderly. Perception of flahes, floating specks or moving clouds may be a conspicuous, but often temporary, feature of the process.

vitreous detachment 

Separation of the vitreous body from the internal limiting membrane of the retina due to shrinkage from degenerative or inflammatory conditions, trauma, progressive myopia, old age, diabetes and in aphakic eyes in which the lens extraction was intracapsular. The most common cases are elderly individuals in whom the posterior part of the vitreous, which becomes liquid, detaches from the internal limiting membrane (called posterior vitreous detachment, PVD). Symptoms are flashes, floaters and photopsia because as the eye moves the vitreous body comes into contact with the retina. The condition is sometimes associated with retinal tears and retinal detachment. See retinal break; syneresis.

The observation that DME prevalence is higher among patients with attached vitreous, and that a posterior vitreous detachment in patients with pre-existing DME may result in resolution of DME has led many to believe that vitrectomy (with removal of any antero-posterior and tangential traction) may be a useful option in the management of DME.
Vitrectomy included removal of the posterior and peripheral vitreous body, induction of the posterior vitreous detachment and peeling of the fibrovascular membranes if present from the retinal surface.
