    It is typically characterized by a clear, bilateral thinning in the inferior and peripheral region of the cornea, although some cases affect only one eye. The cause of the disease remains unclear. Pellucid marginal degeneration is diagnosed by corneal topography. Corneal pachymetry may be useful in confirming the diagnosis.
