Purpose. To determine the correlation between the contour of the optic disc cup and the corresponding hill of vision in primary open-angle glaucoma (POAG) patients. Methods. The optic disc cup slope of 40 POAG patients was measured using the Rodenstock Optic Disc Analyzer. The slope of the superior optic disc cup (SOC) and that of the inferior optic disc cup (IOC) were calculated. These values were compared to the inferior (IHV) and superior hill of vision (SHV), respectively, measured using the Humphrey Visual Field Analyzer. Results. The mean sensitivity of the inferior hill of vision correlated significantly with the mean disc cup slope of the corresponding superior quadrant of the disc, but the mean sensitivity of the superior hill of vision did not correlate with the mean cup slope of the inferior quadrant of the disc in total patients and in the group with C/D>0.6. In patients with C/D≤.6 ,however, the mean sensitivity of the superior hill of vision correlated with the inferior cup slope: C/D≤.6 group C/D>.6 group Total SOC vs IHV r=.46, p=.03 r=.48, p=.04 r=.48, p=.002 IOC vs SHV r=.47, p=.02 r=.16, p=.54 r=.09, p=.57 Conclusions. The inferior and superior quadrantal contours of the optic nerve cup appear to correlate with the sensitivity of their respective hill of vision in patients with early glaucoma (C/D≤.6). However, in patients with more advanced glaucoma (C/D>.6) the contour of the optic nerve seems limited as a predictor of the corresponding hill of vision. This finding is consistent with our clinical impression on the mode of progression of glaucomatous optic nerve damage in POAG patients.
