The Cup-Disc Ratio and Ocular Hypertension

The Cup-Disc Ratio and Ocular Hypertension Abstract To the Editor. —In Table 1 in their article in the November 1986 Archives,1 Katz and Sommer describe the cup-disc ratios and presence of nerve fiber layer defects in ocular hypertensives and control eyes separated by age. It is interesting to note that for both the older and younger age groups, the number of large cups is greater in the ocular hypertensive eyes than in the normal controls. By ×2 analysis, this difference turns out to be highly significant (P <.01). This is true for both the younger and older age groups. For the presence of nerve fiber layer defects, however, application of the Fisher's exact test shows no significant difference in the prevalence of defects between the ocular hypertensive eyes and control eyes for either the younger or older age groups.This is quite interesting. It indicates that while larger cup-disc ratios are found significantly more often References 1. Katz J, Sommer A: Similarities between the visual fields of hypertensive and normal eyes .
