Deep lamellar keratoplasty for pellucid marginal degeneration: review of management options for corneal perforation.

Abstract To report a case of unilateral corneal perforation associated with pellucid marginal degeneration (PMD) and rapid onset and progression of PMD in the second eye. Both eyes underwent subsequent successful management with deep anterior lamellar keratoplasty (DALK). Case presentation with corneal topographic correlation, along with the relevant literature pertaining to surgical techniques used in PMD. DALK was undertaken in both eyes with stable improvement in visual outcome and no rejection episode. DALK is a useful surgical alternative in the management of PMD. The technique provides useful visual rehabilitation in patients with PMD even in the presence of previous corneal perforation.
