The Screening Process
Screening events are held throughout Baltimore City, and are a large part of the recruiting and information collecting process for the SToP Glaucoma study. At each screening, we provide the following free services.

What To Expect At Your Screening
Study Interview
This 10 minute interview involves questions about your vision, demographics, and health. Participation is voluntary.
Presenting Vision Test
This presenting vision test rapidly determines whether you have poor vision (worse than 20/200), decreased vision (worse than 20/40 but equal to or better than 20/200) or good vision (20/40 or better).
Autorefractor Test
The auto-refractor test will identify if you have decreased vision solely due to refractive error. These individuals will be referred for glasses only. This auto-refractor has built-in spectacle correction and therefore can be used to obtain the best-corrected visual acuity.
Fundus Photography
Using fundus photography, we can obtain good optic nerve images for documenting the presence or absence of glaucoma, and can identify other diseases of the macula and blood vessels.
Eye Pressure
While not part of the definition of glaucoma, eye pressure is a key risk factor for the disease; nearly half of those with glaucoma have eye pressure above the normal range. The I-care tonometer that will be used in this screening is a handheld portable device that accurately measures IOP and does not require anesthesia.
