Morphometry of the optic disc was performed in 70 eyes of 50 Japanese patients. A nerve fiber analyzer was used to measure the disc size and shape, with particular attention to sex differences. The series comprised 34 male and 36 female eyes. ages ranged from 23-83 years, average 62 years. The axial length averaged 23.7 ± 1.1 mm in 25 male eyes and 23.1 ± 1.6 mm in 27 female eyes. There was no difference between sexes (p = 0.26). There was no difference in vertical disc diameter between sexes (p = 0.24). The horizontal disc diameter was significantly larger in males than in females (p = 0.03). The value of vertical minus horizontal disc diameter was greater in males (p = 0.06). The ratio of horizontal/vertical disc diameter was greater in males (p = 0.09). These findings suggest that the size of the optic disc is different between males and females, and that the optic disc is more oval-shaped in females. LA: Japanese
