WebA similar pattern was seen for vertical C/D ratio in hyperopia (P = 0.057) but not in myopia (P = 0.428). Conclusions: There was a significant association between spherical equivalent refraction and age (P<0.0001). C/D ratio in persons with NA-AION is significantly smaller than that seen in the general population.

WebIn eyes with normal fields, the cup/disc (C/D) ratio was found to be significantly related to applanation pressure P A level, ratio of pressure reading at the beginning of the tonogram and the tonographic estimate of aqueous outflow activity (P o /C), and C-value. The frequency of C/D > 0.3 increased significantly with the P A level and with the magnitude … WebThe C/D ratio attempts to quantify the extent of axonal (nerve fiber) loss. It compares the diameter of the cup to the entire diameter of the optic nerve head (disc).
