Glaucoma is a group of diseases with characteristic optic atrophy and visual field defect, and pathological increase of intraocular pressure is the main risk factor. Primary glaucoma is a kind of glaucoma whose etiological mechanism is not fully understood. According to the state of the anterior chamber Angle when the intraocular pressure rises - closed or open, it can be divided into angle-closed
