Glaucoma is the number one leading cause of vision loss that is irreversible and the second overall leading cause of blindness in the world. This “sneak thief of sight” disease is vision loss due to damage to the optic nerve and starts with gradual vision loss in the periphery, so many people don’t even notice it happening. Experts say that at least half of the people with glaucoma don’t even know they have it. Glaucoma usually affects middle age people and the elderly, but it can affect any age. African, Asian and Hispanic decent are at a higher risk for this ugly disease. Early detection is key because there is no cure for glaucoma, however, there is treatments available to help slow progression or to prevent vision loss. The best way to monitor for glaucoma or any eye diseases is an annual comprehensive eye exam.
