👉 Pellucid marginal corneal degeneration (PMCD) is a bilateral, noninflammatory, peripheral corneal thinning disease. 👉 It is characterized by peripheral thinning, usually in the inferior cornea. 👉 The ectatic zone, which is 1-2 mm from the limbus, lies above the point of the maximum corneal thinning. 👉 Usually associated with high degrees of against-the-rule astigmatism and low degrees of myopia. 👉 Can be treated by Intrastromal Corneal Ring Segments (ICRS) and has good postoperative results.
