摘要:
Ellipses were fitted to 129 nerve heads and corresponding blind spots in an attempt to determine how faithfully the elliptical nature of the nerve head is reflected in the blind spot. The blind spots are found to be 2 to 3 times more elliptical (based on the ratio of the long axis to the short axis) than the nerve heads. The correlation between the ratios mentioned above is found to be negligible (Pearson r = 0.07 for Goldmann 1–2 blind spots and 0.18 for Goldmann 1–4 blind spots).
