Polymerase Chain Reaction-Guided Diagnosis of Mycotic Keratitis: A Prospective Evaluation of Its Efficacy and Limitations

Abstract

PCR not only proved an effective rapid method for the diagnosis of fungal keratitis, but was also more sensitive in our hands than KOH wetmount and Gram's smear. Barring the potential limitations, PCR remains a promising tool for faster diagnoses of fungal keratitis.
