ABSTRACT
We analysed the optic nerve head of 151 normal eyes with 8 confocal scanning laser ophthalmoscope (TopSSTM, Laser Diagnostic Technologies, Inc.), and obtained the normal values of each parameters. As the optic disc size increases, the cup shape, effective area, 1/2 depth area, C/D ratio, neuroretinal rim area, volume above, volume below, and 1/2 depth volume also increase. Therefore we obtained the normal values of these parameters according to the optic disc size. The entire subjects were divided into four groups according to the disc area, each group of 1. 5mm2-2.0mm2, 2.0mm2-2.5mm2, 2.5mm2-3.0mm2, and 3.0mm2-3.5mm2`, respectively. The normal values of other parameters such as contour variation, rnean contour depth, average depth, maximum depth, average slope, and maximum slope which are not affected by optic disc size were obtained without grouping. This may minimize the error in evaluating the optic disc parameters and may be useful in the early detection of glaucomatous optic disc changes.
