Usually, present with reduced visual acuity owing to high irregular astigmatism in the fourth to fifth decades of life ( 4). The area between the limbus and thinning is clear, without scarring, lipid deposition, or vascularization. Typically the thinning extends from the 4-o’clock position to the 8-o’clock position, 1 mm from the limbus with intact epithelium and normal corneal thickness superiorly. The degeneration is distinguished from other ectatic corneal disorders by its characteristic location and the absence of inflammatory signs. ![]() Although classically described as an inferor entity, the site of involvement can be in any quadrant of the cornea, including the superior part, which is termed superior PMCD ( 2, 3). It is a bilateral disease, although one eye may be affected earlier and clinically diagnosed, while the other eye has no clinical features ( 1). Pellucid marginal corneal degeneration (PMCD) is a noninflammatory ectatic corneal disorder mostly involving the inferior half of the cornea in a crescentic fashion (Fig.
