A Re-scraping was done. In spite of this treatment, the cornea became thinner and an enlargement of the infiltrate was observed. Steroids were not used One month later, second PK was performed in an attempt to improve visual acuity. This entity is not a common cause of corneal infection, but it represents one of the major causes of infectious keratitis in tropical areas of the world. It is important to consider fungus as a possible cause of infectious keratitis because of the devastating ocular damage that it can produce if it is not diagnosed and treated promptly and effectively.
Yeast produce characteristic creamy, opaque, pasty colonies on the surface of culture media.
Candida is the most representative pathogen in this group, affecting primarily corneas compromised by topical steroids, surface pathology, or both. A feathery, or powdery growth on the surface of culture media is produced by septate filamentary fungi, which are the most common cause of keratomycosis. However, the epidemiology of keratomycosis is climate specific. In the Southern United States, Fusarium species are the most common cause of keratomicosis, with an especially high incidence in Florida. Organisms that infect pre-existent epithelial defects belong to the normal microflora of the conjunctiva and adnexa.
