ABSTRACT
Fungal keratitis is an opportunistic infection caused by pathogenic fungi in the cornea. The most common responsible infectious agents for fungal keratitis are filamentous fungi. Fusarium and Aspergillus are the most important and frequently seen filamentous fungi. Eye injuries, existing ocular diseases, topical antibiotics and steroids, contact lens use, systemic diseases (diabetes mellitus (DM)), weakening of the immunity are predisposing causes. Aspergillus flavus keratitis is an eye infection with poor prognosis, difficult to treat and can lead to loss of vision so we aimed to emphasize the importance of Aspergillus flavus isolated in a 54 year old male patient with type 2 DM.
