Myopic person, why easy to have disease of flying mosquito obstacle?

Abstract: some parts of the vitreous liquefy into water, resulting in other parts becoming viscous: some colloidal fibers gather together. When the eyeball turns around, these fibers float around in the eyeball, looking like ants flying around. The eyeball deformation caused by

myopia will make the vitreous in the eye degenerate early and produce all kinds of plankton. This is flying mosquito disease.

and

many people have seen that there are floating objects like mosquitoes or insects flying around in front of them. This phenomenon is flying mosquito disease.

so, how did the flying mosquito disease come from?

vitreous liquefaction and posterior detachment are the main causes.

the eyeball is like an egg, most of which is filled by the vitreous body; The vitreous body is like egg white, which is a transparent and viscous colloidal substance.

with age, glass will “liquefy”, just as eggs will go bad after being put for a long time. Part of the vitreous of

and

liquefy into water, causing other parts to become sticky: some colloidal fibers gather together. When the eyeball turns around, these fibers float around in the eyeball, looking like ants flying around. If vitreous liquefaction continues to develop, it will also lead to vitreous and retinal separation, leading to “posterior vitreous detachment” and “retinal detachment”. The former is only the aggravation of the condition of flying mosquitoes, while the latter is a very serious complication!

if there is no myopia, posterior vitreous detachment usually occurs at the age of 50 ~ 60 years; If there is myopia, some people will have flying ant disease at the age of 20 ~ 30. People with myopia are more likely to have floaters because myopia leads to the enlargement of the eyeball, and the vitreous filling the eyeball will appear less, which will lead to the early liquefaction of the vitreous.
