1. What Is Glaucoma
Glaucoma is a condition of increased pressure within the eyeball, it tends to be inherited and may not show up until later in life. The increased pressure, called intraocular pressure, can damage the optic nerve, which transmits images to your brain. If the damage continues, glaucoma can lead to permanent vision loss. Without treatment, glaucoma can cause total permanent blindness within a few years.
Most people with glaucoma have no early symptoms or pain. Seeing an eye doctor regularly can diagnose and treat glaucoma before long-term visual loss happens. If you are over the age of 40 and have a family history of the disease, a comprehensive eye examination from an eye doctor every year is highly recommended. If you have health problems like diabetes or a family history of glaucoma or are at risk for other eye diseases, you may need to go visit your eye doctor more frequently.
