Popis: To report reference data for optic disc, neuroretinal rim and β-peripapillary atrophy (β-PPA) in normal Japanese. In the Kumejima study, all participants underwent disc stereo-photography; 2208 normal subjects had good-quality disc stereo and β-PPA photographs OU. The disc and rim area and the area and angular extent of β-PPA were evaluated by computer-assisted planimetry. The disc, rim, and β-PPA area and its angular extent OD (OS) averaged 2.54 ± 0.50 (2.53 ± 0.49), 1.67 ± 0.29 (1.67 ± 0.30), 0.47 ± 0.66 (0.42 ± 0.59) mm2, and 99 ± 85 (92 ± 82) degrees (mean ± standard deviation) with bilateral Pearson’s correlation coefficient of 0.890, 0.769, 0.679 and 0.632 (P
