How Common is Glaucoma?

Jan 13, 2022 | Blog Article, Eye Diseases, Glaucoma

Glaucoma is a collection of eye conditions that negatively affect the optic nerve. There are several different types of glaucoma, but the damage is typically caused by abnormally high pressure in the eye.

As a result of this damage, a person can gradually start to lose their vision. In some cases, the early symptoms may not be noticeable, so people don’t realize they have glaucoma until the damage is done. For this reason and because there is no cure, glaucoma is sometimes called the silent thief of sight.

Glaucoma Statistics

Living up to its nickname, glaucoma is common and the second leading cause of blindness as well as the leading cause of irreversible blindness in the world.1,2 Many people are aware of glaucoma, but not everyone recognizes when they have it or gets the eye disease care they need right away.

Worldwide, the prevalence of glaucoma is hard to determine because the early stages may go undiagnosed. By one account, 60.5 million people were affected by open-angle or angle-closure glaucoma in 2010.2 In this same year, glaucoma was believed to be responsible for 6.6% of all blindness and 2.2% of all moderate or severe visual impairments.3

While not exact, the prevalence of glaucoma in the United States is just as alarming. Glaucoma is believed to impact 1.9% of people ages 40 or older which equates to about 2.7 million American.2 These numbers only rise with older populations.

What is also concerning is how common glaucoma is now compared to several years ago. From 1990 to 2010, the percentage of people across the world with glaucoma-related blindness increased by 62%, and the percentage of people with glaucoma-related visual impairment increased by 83%.3

The United States also saw a similar increase in cases of glaucoma around this same time. In just ten years, the number of glaucoma cases jumped from 2.22 million in 2000 to 2.72 million in 2010. Unfortunately, some researchers expect this trend to continue. By 2050, the number of Americans with glaucoma is expected to more than double.4

The Glaucoma Population

Although glaucoma is a common problem around the world, some people are more at risk of developing glaucoma than others. Glaucoma is genetic and tends to be more common in specific populations.

Common traits among the glaucoma population include:

  • Age over 40
  • Family history of glaucoma
  • Diabetes
  • High blood pressure, heart disease, or sickle cell anemia
  • African American or Hispanic descent

Regardless of whether you are at a high or low risk for glaucoma, it can sneak up on you. You should get regular eye exams to catch the condition as early as possible so you can take preventative action.

Although glaucoma has no cure, there are ways to manage the condition to help slow down the progression of the disease.
