Glaucoma surgery is a medical procedure aimed at lowering intraocular pressure to prevent damage to the optic nerve. This condition, known as glaucoma, can lead to vision loss if not treated effectively. The surgery may involve creating a new drainage pathway for fluid in the eye or implanting devices to help regulate pressure. There are different types of glaucoma surgery, including trabeculectomy and tube shunt surgery. The choice of procedure depends on the severity of the condition and the patient's overall health. Post-surgery, patients may need regular follow-ups to monitor eye pressure and ensure the effectiveness of the treatment.
