title: Comments on frontonasal dysplasia, ocular hypertelorism and dystopia canthorum.
abstract: The mean canthal index values of patients with frontonasal dysplasia are tested for differences in facies A, B, C, and D. A general discussion of ocular hypertelorism and dystopia canthorum is presented. Ocular hypertelorism is considered a sign which may occur in a variety of disorders. Quantitative methods for determining ocular hypertelorism are critically reviewed.
