Brain infarcts that compress the eyes and affect the body’s visual range can get better, but they are difficult to cure. Because the brain infarction is blocking the visual center, which is equivalent to the power supply, and the eye is equivalent to the electric light bulb, if the power supply has no electricity, the light bulb will not glow if it is left. There is a kind of cerebral infarction because of the acute edema compression of the visual center, and if the treatment reduces the edema compression of the cerebral infarction, the visual function of the visual center can be restored, and the visual range of the eye is reduced or narrowed, and it can be completely improved. Whether the cerebral infarction compression of the eye visual range reduction can be well depends on how far the acute period can be cured, and the visual range left after three weeks or six months is the posterior period.
