The screening program identified 201 (19.9%) persons with suspicion of glaucoma during the screening process. Six persons could not be assessed due to absence of useful images. Glaucoma suspects were older; had lower visual acuity; and, as expected, more frequently had a personal history of ocular hypertension or glaucoma.
