The disadvantages of glaucoma surgery mainly refer to the risks of the surgery. Generally, glaucoma surgery may trigger complications such as choroidal detachment, ciliary ring block glaucoma, and intraocular infections in patients. Glaucoma is a common disease in ophthalmology, which is a class of diseases that cause visual field defects and optic nerve atrophy due to pathologically elevated intraocular pressure. The main disadvantage of surgical treatment for glaucoma patients is the possibility of postoperative complications, such as choroidal detachment due to a sudden drop in intraocular pressure after surgery, and ciliary ring block type glaucoma. Complications such as intraocular infections may also occur if the glaucoma surgery is not strictly sterilized or if the patient does not pay attention to eye hygiene after the surgery. It is recommended that children with glaucoma visit the hospital in a timely manner to have their condition evaluated and treated according to the doctor’s instructions.
