Anterior floaters in non-vitreous lesions
Introduction
Introduction Congenital physiological floaters are a type of physiological floater. Most of the mosquitoes are benign, or "physiological floaters," which are "good mosquitoes". Only a few of them pose a serious threat to the eyeball. It is a "bad mosquito." Experts believe that about 80% of the mosquitoes are formed by the hydration of vitreous fibers, which is benign. The light reaches the omentum through the vitreous, and the optic nerve cells on the omentum stimulate the visual information of the visual network to be transmitted to the brain. Light passes through the turbidity and is projected onto the retina. The vitreous becomes 80% colorless and transparent gelatin and 20% liquid. The vitreous plastid becomes vitrosin (vitrosin is composed of transparent collagen fibers) and its role is to protect microseisms from the outside.
Cause
Cause
The light passes through the vitreous and reaches the omentum. The optic nerve cells on the omentum stimulate the visual information of the visual network and transmit it to the brain. Light passes through the turbidity and is projected onto the retina. The vitreous becomes 80% colorless and transparent gelatin and 20% liquid. The vitreous plastid becomes vitrosin (vitrosin is composed of transparent collagen fibers) and its role is to protect microseisms from the outside. 80% colloid and 20% liquid on the vitreous body. As the age of the person grows, the degeneration of the vitreous body is caused by vitreous degeneration. It is a natural aging phenomenon, that is, it is the original gel state with ageing. , "liquefaction" changes in the tissue on the vitreous. 40% colloid, 60% liquefied.

When a normal person looks at a white object or a blue sky, it can be found that there are small dots or filament floats floating in front of the eyes, sometimes closed eyes can be seen, but objective examination can not find any vitreous lesions. It is a physiological floater. It is generally thought that it is caused by the projection of cells of the vitreous cortex or blood cells walking in the blood vessels of the retina on the retina. No treatment is needed.
Diagnosis
Differential diagnosis
It needs to be differentiated from senile physiological floaters and myopic physiological floaters.
