Glaucoma is called “the sneak thief of sight” since there are no symptoms and once vision is lost, it’s permanent. As much as 40% of vision can be lost without a person noticing.
Glaucoma is the leading cause of preventable blindness. Moreover, among African American and Latino populations, glaucoma is the leading cause of blindness, and it is more prevalent. Glaucoma is 6 to 8 times more common in African Americans than Caucasians.
Over 4 million Americans, and nearly 70 million people worldwide, have glaucoma. Experts estimate that half of them don’t know they have it. Combined with our aging population, we can see an epidemic of blindness looming if we don’t raise awareness about the importance of regular eye examinations to preserve vision.
In the United States, approximately 120,000 are blind from glaucoma, accounting for 9% to 12% of all cases of blindness.
What is Glaucoma?
Glaucoma is a group of eye diseases that gradually steal sight without warning. Although the most common forms primarily affect the middle-aged and the elderly, glaucoma can affect people of all ages.
Vision loss is caused by damage to the optic nerve. This nerve acts like an electric cable with over a million wires. It is responsible for carrying images from the eye to the brain.
There is no cure for glaucoma—yet. However, medication or surgery can slow or prevent further vision loss. The appropriate treatment depends upon the type of glaucoma among other factors. Early detection is vital to stopping the progress of the disease.
Types of Glaucoma
There are two main types of glaucoma: primary open-angle glaucoma (POAG), and angle-closure glaucoma. These are marked by an increase of intraocular pressure (IOP), or pressure inside the eye. When optic nerve damage has occurred despite a […]
