Outcomes of Pythium keratitis: a meta-analysis of individual patient data.

Background: Pythium keratitis is a difficult-to-treat corneal infection.

Methods: A meta-analysis of individual patient data from observational studies of Pythium keratitis was performed. The outcomes of interest were therapeutic penetrating keratoplasty (TPK) and globe removal (evisceration, enucleation, or exenteration); the main exposures were linezolid and azithromycin use.
