Why does vitreous body muddy meet myopia?

summary

Transparent gel in vitreous body, if there is an opaque body, it is called vitreous body opacity (vitreous opacities). Normal vitreous body is a transparent gel, and tends to change with age. The main manifestation is condensation and liquefaction, which is the result of depolymerization of polysaccharide. Some vitreous opacities are caused by pathological reasons, which can be the result of complications or development of many inner eye diseases. The most common are senile degeneration, myopic changes, posterior vitreous detachment and physiological flying mosquito disease. In addition, retinal detachment, uveitis, primary familial amyloidosis, flash vitreous liquefaction and other clinical manifestations can also appear in front of the eyes. So let's share the following about why vitreous opacity can cause myopia? The knowledge of.

Why does vitreous body muddy meet myopia?

First: inflammatory vitreous opacity: vitreous is non vascular tissue, vitreous inflammation is caused by the spread of inflammation in surrounding tissue. Such as iridocyclitis, chorioretinopathy. The exudates, inflammatory cells, necrotic tissues, pigment granules and phagocytes of inflammatory tissue adhere to vitreous fibrous tissue and produce a variety of different types of opacification.

Second: traumatic vitreous opacity: blunt ocular trauma, penetrating injury often accompanied by intraocular hemorrhage and turbidity, intraocular foreign bodies and secondary infection also lead to turbidity. Pigment, trauma and uveitis make pigment particles enter vitreous.

Third: vitreous degeneration and opacity: with the growth of age, vitreous degeneration gradually occurs, manifested as condensation and liquefaction. The condensed part has high density and can have flocculent, filamentous, colorless and transparent turbidity. The structure of vitreous body in liquefying area disintegrated and formed a space full of liquid. This kind of vitreous opacity is more common in high myopia and the elderly, and does not affect vision. It is more common in the elderly and high myopia.

matters needing attention

1. Usually pay attention to rest, do not use eyes too much, avoid the formation of myopia. Avoid "staring", pay attention to the frequency and time of blinking, often blinking can reduce the time of eye exposure to the air, avoid the evaporation of tears. 2. It is not suitable to blow the air conditioner for a long time to avoid airflow on the seat, and tea should be placed near the seat to increase the surrounding humidity. 3. Eat more fruits, especially citrus fruits, and eat more green vegetables, grain, fish and eggs. Drinking more water also helps to reduce dry eyes. 4. Keep good living habits, get enough sleep and don't stay up late. 5. Avoid long-term continuous operation of the computer, pay attention to the rest, usually continuous operation for 1 hour, rest for 5-10 minutes. At rest, you can watch the distance or do eye exercises. 6. Keep good working posture. Maintain a most appropriate posture, so that both eyes look flat or slightly down at the screen, which can make the neck muscles relaxed and minimize the area of the eye exposed to the air. 7. Adjust the distance of the screen. The recommended distance is 50-70 cm, and the screen should be 10-20 cm below the eye level, with a 15-20 degree downward view. Because the angle and distance can reduce the demand for refraction, reduce the probability of eye fatigue. 8. If you have less tears secretion, eyes easy to dry, in front of the computer is not suitable for using contact lenses, to wear frame glasses. For people who wear contact lenses in front of the computer, it is also best to use the kind with high oxygen permeability. 9. For people over 40, it's better to use bifocal lenses, or wear glasses with lower power when typing. 10. If you have red eyes, burns or foreign body sensation, heavy eyelids, blurred vision, even eyeball pain or headache, and still have no obvious improvement after rest, you need to go to the hospital. 11. Usually pay attention not to direct the eyes with strong light to prevent eye injury.
