Crescentic Lamellar Keratoplasty for Terrien Marginal Degeneration

Contributors: Jesse M. Vislisel, MD and Kenneth M. Goins

September 24, 2015

This patient with Terrien marginal degeneration had severe thinning in the right eye (see related atlas entry for pre- and post-operative photos and diagnostic studies). He was filtering aqueous through the area of superior thinning, resulting in positive Seidel testing and creation of an adjacent conjunctival bleb. He underwent a crescentic lamellar keratoplasty to repair the defect and offer tectonic stability, as seen in this procedural video.
