HealthDay News — According to the Glaucoma Research Foundation, the number of glaucoma cases — which affects more than 3 million Americans — is expected to surge to more than 4 million by 2030.

Worldwide, 4.5 million people are blind due to glaucoma, according to the World Health Organization. In the United States, up to 12% of all cases of blindness stem from the disease. 

Blacks, Hispanics and Asians are disproportionately affected, the Glaucoma Research Foundation notes. Others at greater risk for glaucoma include older individuals, people with relatives who have glaucoma, those with diabetes and people who are very nearsighted.

As the population ages, a blindness epidemic may develop if glaucoma awareness doesn’t increase and more people don’t get routine eye exams, the foundation warns. The group says the best way people can protect their vision is to have regular comprehensive eye exams, which can lead to earlier detection and treatment.
