title: The correlation of functional and structural measurements in glaucoma patients and normal subjects.
abstract: We measured a number of structural characteristics of the optic nerve head and retina in 52 glaucoma suspects, 51 glaucoma patients, and 28 normal eyes. In all of the patients, a number of psychophysical functions were recorded and evoked cortical potentials and pattern electroretinography were obtained. The correlations between these structural and functional parameters were established by multiple regression. Diffuse structural changes in the optic nerve head and retina were related to differential light threshold and color that measure diffuse psychophysical disturbances. Localized changes in the retinal nerve fibers and the vertical cup/disk ratio related to the "corrected loss variance," which is an index measuring localized psychophysical changes.
