OHTS-EGPS 2007 Table 6

OHTS-EGPS 2007 Table 6: 5-year primary open-angle glaucoma risk in untreated ocular hypertension from age, mean IOP (mm Hg), mean central corneal thickness (microns), mean vertical cup-disc ratio, and mean Humphrey pattern standard deviation (dB). Point bands map to 4%, 10%, 15%, 20%, or 33%. No race (dropped in the multivariate model). No diabetes term. Not a glaucoma diagnosis or drop order. magent does not measure IOP or pachymetry.
