Abstract
To report corneal topographic patterns in asymptomatic family members of a patient with pellucid marginal degeneration. Computer-assisted corneal topography was used to study the corneas of five family members of a patient with pellucid marginal degeneration. In all five asymptomatic family members, corneal biomicroscopy was normal. Corneal topography, however, showed various abnormalities in different members of this family, particularly a topographic pattern suggesting keratoconus in one family member and a topographic pattern suggesting pellucid marginal degeneration in another family member. This study reinforces the hypothesis that corneal ectatic disorders may represent different manifestations of a clinical spectrum.
