Complications of glaucoma are the problems that can arise from the disease itself or from treatments used to control it. The most serious consequence is progressive damage to the optic nerve, which causes permanent loss of peripheral or central vision and can lead to blindness if not managed. High eye pressure can also cause pain, a cloudy cornea, and, in sudden cases, an emergency with severe vision loss and nausea. Treatments have their own risks: eyedrops may irritate or cause side effects, and laser or surgical procedures can lead to infection, bleeding, scarring, or changes in vision. Specific surgical issues include low eye pressure that can threaten sight, cataract formation after some procedures, and problems with implants such as exposure or malfunction. Scarring is a common reason glaucoma returns and may require repeat treatment or different approaches. Beyond the physical effects, narrowing vision makes daily tasks like reading, driving, and moving around harder, and many people experience anxiety, depression, or loss of independence. Regular checkups and sticking to a treatment plan greatly reduce the risk or severity of complications because early changes are often treatable, and prompt care for new symptoms improves the chance of preserving sight.
