Vitreous opacity?

summary

Vitreous opacity is also known as flying mosquito disease. Intravitreal hemorrhage of embryonic cells or tissues, retina or uvea, hemorrhage or exudate of hypertension, diabetes and uveitis, and vitreous degeneration of high myopia in the elderly can lead to vitreous liquefaction and opacity. Others such as ocular trauma, persistent intraocular foreign bodies, parasites or tumors can also occur vitreous opacity. Vitreous opacity? Let's talk about it

Vitreous opacity?

More significant vitreous opacity symptoms: common in myopia, uveitis and vitreous hemorrhage. The patient felt a large amount of dark shadow in front of him, and his vision decreased to varying degrees. Inspection of the fundus can be found, such as dust or thick flocculus floating, serious cases can not see the fundus, or even fundus without red light reflection, dark.

The rupture of neovascularization leads to vitreous hemorrhage again. This vicious circle eventually leads to neovascular glaucoma and atrophy of eyeball. After massive vitreous hemorrhage, the aqueous barrier was destroyed. The degenerative red blood cells in the vitreous cavity enter the anterior chamber, block the angle of the anterior chamber, and further develop into blood shadow cell glaucoma. Vitreous opacity is a dangerous sign before blindness. If it can be treated in time, it can avoid the development of the disease and save the vision. For example, vitreous opacity leads to retinal detachment, but if we carefully check when vitreous disease just appears, sometimes dry holes can be found, as long as laser treatment can avoid the formation of mesh detachment

Mild vitreous opacification: the patient felt that the shadow was floating in front of his eyes, just like flies and mosquitoes. The onset was sudden and the disease developed rapidly. With the location and degree of vitreous opacity, the degree of affecting vision is different. Mild haze has little effect on vision.

matters needing attention

Although the vast majority of floaters are harmless symptoms, but a few of them are serious eye diseases, such as retinal detachment or vitreous hemorrhage, so we must not take it lightly. If you have the following phenomena, you need to be especially alert and find a qualified ophthalmologist in time for detailed examination: for example, severe vision loss, visual distortion or distortion; Red eyes, pain, photophobia and excessive secretion of tears; With fixed shadow; Or flash; A large number of black spots appear suddenly. Because of more intraocular bleeding, retinal detachment and other causes of flying mosquito disease is the need for surgical treatment.
