• Three case reports illustrate a manifestation of Terrien's marginal corneal degeneration, the pseudopterygium. When present, the pseudopterygium has a characteristic appearance, which is of diagnostic value. This condition occurs at positions other than the 3- and 9-o'clock positions, and it grows onto the cornea at an oblique axis and has a rather broad, flat, leading edge. The pseudopterygium may appear extremely early in the disease when the marginal furrow may still be a subtle finding.
