​Infectious Diseases and Microbiology - Fusarium keratitis ( Fusarium) 
Fusarium keratitis is a highly consequential illness that affects the cornea. Contributing elements encompass physical injury, persistent eye conditions, and the use of contact lenses. Fusarium is an opportunistic fungus that belongs to the hyalohyphomycosis group, which also includes Scedosporium and Penicillium. This group is characterized by the presence of filamentous hyphae that lack color in their cell walls.

Keratitis is defined by ocular discomfort and inflammation of the cornea, accompanied by lacrimation, discharge, and sensitivity to light.
Fusariosis can manifest with various clinical signs, such as cutaneous lesions (most prevalent), rhinocerebral syndrome, endophthalmitis, pneumonia, and widespread infection. This is especially observed in individuals who are neutropenic, have burns, or have undergone transplantation.

The histopathology and pathophysiology of Fusarium closely resemble those of aspergillosis. Cell-mediated immunity is the primary factor that determines resistance to Fusarium.

The study of tissue biopsy specimens from patients with fusariosis shows hyphae that closely resemble Aspergillus, aiding in the diagnosis. Accurate diagnosis necessitates the identification of the culture.
Fusariosis exhibits varying reactions to treatment with amphotericin B or azoles.
