title: [Changes in optic disc rim color with glaucomatous visual field damage--a quantitative study on pattern of color changes].
abstract: We developed a new computerized method for measuring the color of the optic disc directly with objective reproductivity. We compared the optic disc color with sensitivity loss in visual fields corresponding to the disc area measured by Humphrey Field Analyzer. 11 normal eyes, 40 glaucomatous eyes, and 27 eyes with ocular hypertension were studied. In the temporal segment of the disc rim, with the exception of the area, a significant correlation between rim color and sensitivity loss was detected. In the nasal rim and macular area, however, the correlation was less significant in early stage glaucoma. Compared with normal discs, glaucomatous discs showed significant decrease in the red color element of the rim area, and some discs with ocular hypertension showed a decrease without any visual field defect.
