The success rate of surgery for open angle glaucoma is around 50%, but there are many factors affecting the success rate of surgery, and the specific success rate of surgery is related to the patient’s condition. Open angle glaucoma is one of the more harmful types of glaucoma, causing painless vision loss. In the early stages of the disease, there are no typical features, and most patients will miss the best time for treatment. Most patients will miss the best time for treatment, and most of them have already reached the advanced stage when they are examined, which will increase the difficulty of treatment. Surgery is feasible for patients with open-angle glaucoma, with a success rate of about 50%, but there are individual differences in the success rate of surgery. During surgery, due to the damage to the tissues of the body, it is very likely to cause an increase in intraocular pressure during the recovery process, which affects normal recovery and leads to a lower success rate. The success rate of surgery is not clear due to the fact that each patient’s condition and recovery are different, all of which will affect the success rate of surgery. It is recommended that patients with open-angle glaucoma consult a doctor in a timely manner to assess their condition and follow the doctor’s instructions to avoid delays.
