When eye blindness occurs, it is necessary to go to the hospital as soon as possible for examination. Depending on the different causes of eye blindness, medication, laser, surgery and other treatments will be taken to try to improve vision. For eye blindness caused by retinal artery blockage, patients need to have eye massage, oxygen, anterior chamber puncture, periocular injection of vasodilating drugs, such as compound camphorine injection, etc., as far as possible to save vision. For eye blindness caused by glaucoma, patients need to immediately use intraocular pressure-lowering drugs, such as timolol maleate eye drops, brinzolamide eye drops, etc. Patients can also use laser and surgery to reduce intraocular pressure, such as laser iris perforation, trabeculectomy, etc., to reduce intraocular pressure within the normal range, and improve vision as much as possible, but it is generally more difficult to recover. For eye blindness caused by cataract, patients can have surgical treatment. At present, most of them adopt cataract ultrasonic emulsification combined with IOL implantation, which improves vision by removing cloudy lens and implanting clear IOL. It is recommended that patients with vision loss should consult a hospital for evaluation of their condition and follow the doctor’s instructions for treatment.
