What is Terrien's Marginal Degeneration?
Terrien's marginal degeneration is a rare, slowly progressive, non-inflammatory thinning of the peripheral cornea, typically starting superiorly. It causes increasing against-the-rule astigmatism as the thinning progresses, making vision correction with standard glasses increasingly difficult. The peripheral thinning can eventually threaten corneal integrity. Scleral lenses are effective for vision correction, and Pentacam tomography is used to monitor progression.
