The vitreous humor is a clear, gelatinous body located in the vitreous cavity of the eye that supports the retina. The vitreous body often develops pathological changes with age, such as vitreous liquefaction, collagen fibrillation and posterior vitreous detachment.
Posterior vitreous detachment often occurs with age, mostly in patients with high myopia, but can also be secondary to vitreous inflammation, hemorrhage, and other diseases. The treatment of posterior vitreous detachment is mainly aimed at early detection of fissures and early treatment. However, there is no specific treatment for posterior vitreous detachment. Therefore, patients with posterior vitreous detachment need to have their fundus carefully examined for early detection of the fissure and early treatment.
