Glaucoma patients with black spots in their vision after surgery are generally considered to be caused by anterior chamber hemorrhage or vitreous clouding, and can be given general treatment or medication according to the cause. Anterior chamber hemorrhage: Glaucoma is a disease caused by elevated intraocular pressure, which usually requires surgical treatment to establish artificial aqueous drainage channels and lower intraocular pressure to treat glaucoma. A common complication of surgery is anterior chamber hemorrhage, which can cause the symptom of seeing black spots. Semi-recumbent rest can be performed, and if necessary, hemostatic drugs such as aminocaproic acid can be given, or combined with hormone therapy such as methylprednisolone. Vitreous clouding: it can be manifested as a black shadow, usually movable, and can be diagnosed by doing ophthalmic ultrasound and funduscopic examination. Oral lecithin complex iodine tablets and other drugs can be used to promote the absorption of vitreous clouding, so as to eliminate the symptoms. Glaucoma patients with black spots after surgery should consult a doctor in time, and the specific treatment should be carried out under the guidance of the doctor.
