Glaucoma is a condition that causes damage to your optic nerves and gets worse over time. The increased pressure inside your eye, called intraocular pressure, can damage the optic nerves, which transmits images to the brain. If damage to the optic nerve from high eye pressure continues, glaucoma will cause permanent loss of vision. Most people with glaucoma have no early symptoms or pain from this increased pressure, so it’s important to see your eye doctor regularly so that glaucoma can be diagnosed and treated before long-term visual loss occurs.
