title: Racial variation of optic disc parameters in children.
abstract: The optic disc parameters of 66 children without ocular disease were analyzed in a prospective study. The vertical disc diameter, the disc area, and the cup-to-disc ratio were significantly larger in blacks than in whites. The race-based variation of optic disc size demonstrated previously in adults appears to be inherited, as it is also present in children.
