Pellucid marginal degeneration
A rare disorder of the anterior segment of the eye characterized by slowly progressive bilateral non-ulcerative non-inflammatory clear thinning of the inferior portion of the peripheral cornea (extending from the 4 o’clock to the 8 o’clock position) with an area of corneal protrusion above the point of maximal thinning resulting in against-the-rule astigmatism with decreased visual acuity. The central cornea is of normal thickness.
