Fungal Keratitis Diagnosis and Testing

Your eye doctor will examine your eye and may possibly take a tiny scraping of your cornea. The sample will be sent to a laboratory to be examined under a microscope or cultured. Polymerase chain reaction (PCR) and confocal microscopy are also being used as newer, faster forms of diagnosis; however, culture from corneal scrapings is considered to be the standard for definitive diagnosis of fungal keratitis.
