Fungal keratitis is a serious infection of the cornea that can result in severe visual impairment. It is caused by various types of fungi, including Fusarium species and Aspergillus species.
Causes[edit]
Fungal keratitis is most commonly caused by the Fusarium species of fungi, but it can also be caused by the Aspergillus species and other types of fungi. These fungi are often found in the environment, particularly in soil and decaying organic matter.
Symptoms[edit]
The symptoms of fungal keratitis can vary, but they often include eye pain, blurred vision, redness of the eye, sensitivity to light, and excessive tearing or discharge. In some cases, a white or gray patch may be visible on the cornea.
Diagnosis[edit]
Diagnosis of fungal keratitis typically involves a thorough examination of the eye, including a slit lamp examination. In some cases, a sample of tissue may be taken from the cornea for laboratory testing.
Treatment[edit]
Treatment for fungal keratitis usually involves the use of antifungal medications, which may be applied as eye drops or given orally. In severe cases, surgery may be required to remove the infected portion of the cornea.
Prevention[edit]
Prevention of fungal keratitis primarily involves good eye hygiene and proper care of contact lenses, if used. It is also important to seek prompt medical attention for any eye injuries, particularly those involving plant material or soil.
