Corneal perforation associated with pellucid marginal degeneration and treatment with crescentic lamellar keratoplasty: two case reports.
OBJECTIVE
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.
