The authors evaluated the morphology of disc excavation and visual field defects in 38 eyes with chronic open-angle glaucoma. Changes in the optic disc were measured by optical coherence tomography (OCT). The visual field was examined using Program 30-2 of the Humphrey Field Analyzer. The parameters were analyzed by a linear regression model. The cup/disc ratio (C/D) was linearly correlated with the mean deviation (MD) of the visual field (r = 0.328, p = 0.0443) and with pattern standard deviation (PSD) (r = 0.354, p = 0.0294). The undermining diameter/disc ratio (UD/D was linearly correlated with PSD (r = 0.342, p = 0.0355) and not with MD (r = 0.196, p = 0.2390). The undermining index (UI), or undermining diameter/cup ratio, was not correlated with either MD (r = 0.092, p = 0.5838) or PSD (r = 0.073, p = 0.6622). These findings show the absence of undermining of the optic disc, as related to the visual field defect. Linear tomography with OCT was useful in the quantative evaluation of undermining of the glaucomatous optic disc. LA: Japanese
