Congenital glaucoma refers to optic nerve damage and visual field loss caused by abnormal embryonic development and congenital variation of the angle structure, which leads to aqueous humor drainage obstruction and increased intraocular pressure. Foreign data show that the incidence of primary infantile glaucoma is 0.008%, while in my country it is 0.002%~0.0038%, and one in ten thousand newborns. 2~15% of blind people are blinded by congenital glaucoma. 80% of infantile glaucoma occurs within 1 year old, and some occur at birth. Therefore, the eye damage caused is more serious than that of adults. It not only causes blindness, but also seriously affects the appearance, and there are many serious secondary lesions, and even leads to eye rupture.
