Pellucid


Definition:

  • (a.) Transparent; clear; limpid; translucent; not opaque.

Example Sentences:

  • (1) Three patients had pellucid marginal corneal degeneration complicated by corneal edema.
  • (2) Our computer-based corneal topography analysis system was used to study the keratoscope photographs (keratograms) from two patients with classic pellucid marginal degeneration and a third patient with no inferior corneal thinning, whose keratoscope mire pattern was suggestive of the condition.
  • (3) We performed central pachymetry on two patients with pellucid and Terrien's corneal marginal degeneration with mean central corneal thicknesses of .487 mm and .466 mm, respectively.
  • (4) Pellucid marginal corneal degeneration is a bilateral disease characterized by a narrow band of corneal thinning localized 1-2 mm from the inferior limbus.
  • (5) Follicles were classified on the basis of the number of layers of follicle cells, the presence and degree of development of the zone pellucide, and the presence of an antrum.
  • (6) Pellucid marginal degeneration of the cornea is a bilateral, clear, inferior, peripheral corneal-thinning disorder.
