Purpose:
To describe 2 cases of corneal perforation associated with pellucid marginal degeneration (PMD) and subsequent successful management with crescentic lamellar keratoplasty.
Methods:
Two cases are discussed along with the relevant literature.
Results:
Both patients presented with spontaneous corneal perforations and associated features consistent with PMD. In both cases, there was fellow eye evidence of PMD, and 1 of the patients was already known to our unit with this diagnosis. Initial conservative measures were unsuccessful, and both patients underwent crescentic lamellar keratoplasty as the definitive surgical management with a good visual outcome.
Conclusions:
Crescentic lamellar keratoplasty is an effective technique for the management of this rare complication of PMD.
