Glaucoma is a commonly undiagnosed condition. Awareness of the condition is needed to identify individuals at high risk of developing it so they can be screened and treated.
Glaucoma is the most prevalent optic neuropathy, affecting an estimated 70 million people worldwide. The most common form of glaucoma is primary open-angle glaucoma (POAG), which is an asymptomatic chronic condition that progresses silently until it affects central vision in the advanced stages of the disease. At least 50% of patients with glaucoma in Europe, the USA and Australia remain undiagnosed, with rates approaching 90% in developing countries. Widespread population-based screening for glaucoma is not thought to be cost-effective or efficient. However, improved awareness of the condition and case detection through screening of high-risk individuals has been shown to be beneficial.
