Fungal eye infections are very uncommon, yet they may be severe, leading to lasting visual problems, including blindness. An eye injury is the most common cause of a fungal eye infection, particularly if the harm was inflicted by plant material such as a thorn. Several microbes, including bacteria, viruses, amoeba, and fungi, may cause eye infections.
Fungi of several sorts may enter the eye and produce an infection. Fusarium, Aspergillus, and Candida are examples of fungi that can cause an infection. The fungus usually enters the eye through an injury, such as unintentionally scratching the eye with a tree branch. In exceptional cases, a person’s body may acquire a fungal infection that extends to their eyes.
