Glaucoma is an eye disease characterized by increased intraocular pressure, which can damage the optic nerve and lead to vision loss. Glaucoma surgery is aimed at lowering eye pressure to prevent further optic nerve damage. Various surgical options are available, including trabeculectomy, laser surgery, and minimally invasive glaucoma surgery (MIGS). Regular monitoring and timely surgical intervention are key to preserving vision in patients with glaucoma.
