Effect of Community Screening on the Demographic Makeup and Clinical Severity of Glaucoma Patients Receiving Care in Urban China

Glaucoma patients detected through community screening had significantly milder damage, and were more likely to include underserved groups (women, elderly) than those newly diagnosed in a clinic in this setting. Comparison with population studies suggests that cases of glaucoma with IOP < 21 mm Hg are severely underascertained in China, a situation that may be improved by screening.
