|Description:||This photomicrograph was from a tissue sample from a patient diagnosed with a case of mycotic keratitis, also referred to as fungal keratitis, which was due to a Fusarium sp. fungal organism.|
Keratitis is an inflammation of the cornea (the clear, front part of the eye) and is often caused by an infection. Bacteria, viruses, amoeba, and fungi can all cause keratitis. Fungal keratitis is an inflammation of the cornea that is caused by a fungus. Types of fungi that have been known to cause fungal keratitis include:
- Fusarium species
- Aspergillus species
- Candida species
Fusarium and Aspergillus species live in the environment, often in association with plant matter. Candida species are some of the microorganisms that normally live on human skin and mucous membranes. Although fungal keratitis can be a serious condition, it is very rare.
