What is Fungal Keratitis?
Fungal keratitis is an infection of the cornea. The cornea is the clear, dome-shaped window of the front of your eye and focuses light into your eye. Fungal keratitis can develop quickly from an eye injury or contact lens use. It can cause blindness if it is not treated. In some cases, treatment cannot restore vision. In these cases, permanent vision impairment or blindness may occur.
There are many different fungi that can infect the cornea such as Fusarium, Aspergillus or Candida.
