Neuroretinal rim areas and visual field indices in glaucoma.
Magnification-corrected measurements of neuroretinal rim area of the optic disk were correlated to visual field indices calculated from 49 thresholds of Octopus program JO. The indices express overall reduction and localized disturbances of retinal sensitivity. The study was composed of 123 subjects, including 23 normal subjects, 49 patients suspected of having glaucoma, and 51 patients with glaucoma. The neuroretinal rim area was highly significantly correlated with both visual field indices; the index for overall loss of retinal sensitivity had a somewhat higher correlation coefficient than the index expressing localized visual field changes. Adequate fit of visual field data on rim area was achieved by quadratic regression.
