The intrapapillary morphometric data of 290 optic nerve heads of 158 patients with chronic primary open-angle glaucoma and of 253 unselected normal subjects were correlated with the visual field indices of Octopus program 32,34-Delta. Only one eye per patient was considered. Significant correlations (P less than 0.001) were revealed for the neuroretinal rim (NRR) area as a whole and in four defined disc sectors, the ratio of lower temporal to upper temporal rim area, the rim width, the optic cup area and diameters, the horizontal and vertical cup/disc (c/d) ratios, and the quotient of horizontal to vertical c/d ratio. Correlation coefficients ranged between 0.30 and 0.77. They were highest for the rim area of the inferior temporal disc sector, followed by the superior temporal, nasal, and temporal sectors. There were no correlations for the optic disc size and form. The topographic morphometry of the intrapapillary optic disc structures was unremarkable in four glaucomatous eyes with small discs.
