title: PCR for the molecular diagnosis of mycotic keratitis.
abstract: Mycotic keratitis, an infection of the cornea caused by fungi, is a medical emergency, with patients presenting with considerable pain and distress. For effective management of the condition, a specific diagnosis must be made rapidly to permit early initiation of antifungal therapy. Currently, direct microscopic examination and culture of corneal material constitute the 'gold standard' for diagnosis. However, rapid, sensitive yet specific tests are needed to detect a small number of, or nonviable, fungi. PCR has many potential advantages when used as a diagnostic aid for mycotic keratitis; the present review covers these advantages, and possible limitations. An expert assessment is also made of studies that have used PCR for the diagnosis of mycotic keratitis. The review concludes with a Five-year view of the potential impact of PCR in management of mycotic keratitis.
