PURPOSE:To determine the cup and disc areas using computer-aided imaging. METHODOLOGY:Case-control study using the computer-aided imaging as a screening test in a given population. RESULTS:There is a wide variability in cup and disc areas among glaucoma suspects and normal. CONCLUSION:C:D alone has a poor predictive value for diagnosing glaucoma.Optic disc size with C:D is just as sensitive and specific in screening for glaucoma.Cup and disc areas are positively correlated for normal and glaucoma suspects.
