Glaucoma is a disease characterized by atrophy and depression of the optic papilla, visual field defect and vision loss, and pathological increases in ocular tension are one of the primary risk factors for its onset. Glaucoma is caused by a disruption of the dynamic balance of the aqueous humor circulation, and the increased intraocular pressure causes optic nerve damage by both mechanical compression and by a mechanism that causes optic nerve ischemia. Clinically, ocular pressure reduction is considered to be a relatively effective means for treating glaucoma, and the ocular pressure reduction method generally adopts medicines or surgical treatment, medicines generally adopt miotics or beta-adrenal glands and the like for treatment, if the effect of the medicines is not ideal, surgical treatment is considered, and trabeculotomy is generally adopted for operation, but complications such as anterior chamber and choroidal separation, bleb fibrosis, bleb infection and the like are easily caused after operation.
