Fungal keratitis
Fungal Keratitis
Fungal keratitis (pronounced: fun-gal ker-a-ti-tis) is a serious infection of the cornea, the clear front surface of the eye. This condition is often caused by fungi in the Fusarium or Aspergillus species, but can also be caused by other types of fungi.
Etymology
The term "fungal keratitis" is derived from the Greek words "mykes" (fungus) and "kerato" (horny, referring to the cornea).
Causes
Fungal keratitis is most commonly caused by the Fusarium and Aspergillus species of fungi. These fungi are often found in organic matter such as soil, plants, and decaying fruits. Other fungi that can cause keratitis include Candida, Penicillium, and Cryptococcus.
Symptoms
Symptoms of fungal keratitis can include redness, pain, blurred vision, sensitivity to light, and excessive tearing or discharge. In severe cases, it can lead to blindness.
Diagnosis
Diagnosis of fungal keratitis typically involves a detailed examination of the eye, including a slit lamp examination. Laboratory tests, such as cultures or biopsy, may also be used to identify the specific type of fungus causing the infection.
Treatment
Treatment for fungal keratitis usually involves antifungal medication, either in the form of eye drops or oral medication. In severe cases, surgery may be required to remove the infected cornea and replace it with a healthy donor cornea.
Prevention
Prevention of fungal keratitis involves good eye hygiene, avoiding injury to the eye, and proper care of contact lenses. People who work in environments where they are exposed to fungi (such as gardeners or farmers) should wear protective eyewear.
