In previous studies,^1-3 white persons had notably smaller optic discs than Hispanics who had smaller optic nerve heads than Asians. The optic discs were largest in African Americans. Considering this race dependence of the optic disc size, we conducted this study to evaluate, whether within a circumscribed group of white subjects, the size of the optic disc depends on the pigmentation of the individual. As measure for pigmentation, we took the color of the iris.

The study included 203 white subjects (100 women, 103 men), with a mean (±SD) age of 42.3±12.6 years and a mean (±SD) refractive error of -0.16±1.95 diopters (D). The subjects living in the northern region of Bavaria, Germany, were normal individuals, who were prospectively and consecutively examined and served as a normal control group in an ongoing study on the biomorphometry of the optic nerve.⁴ Highly myopic eyes with a myopic refractive error exceeding -8 . . .
