Pediatric youth

Cortical blindness is a type of central visual dysfunction caused by toxins or vasospasm caused by toxins in the cerebral occipital cortex, and vasospasm damage is the most common. The clinical manifestations are complete loss of binocular vision, normal pupil light reflection, normal fundus, and hemiplegia. The disease is common in children 2 to 6 years old. Modern western medicine generally uses corticosteroids and vasodilator drugs, but the effect is not very satisfactory. Cortical blindness is equivalent to pediatric blue blindness in Chinese medicine. As stated in "Yinzong Jinjian. Ophthalmology Mind Tips": "Children are blind, because of fetal wind and evil, the pupil is good after birth, black and white, but the thing is not visible." It is believed to be related to inadequate endowment and liver and kidney loss.
