Fungal Keratitis

Fungal keratitis is an infection of the cornea, the clear outer layer of the eye, caused by a fungus. It is a serious eye infection that can cause vision loss if not treated promptly. Fungal keratitis is most common in tropical and subtropical climates, but can occur anywhere. It is more common in people who wear contact lenses, have a weakened immune system, or have an eye injury.

Causes of Fungal Keratitis

Fungal keratitis is caused by a fungus that enters the eye through an injury or trauma. It can also be caused by contact lens use, especially if the lenses are not cleaned properly. People with weakened immune systems are more likely to develop fungal keratitis.

Diagnosis of Fungal Keratitis

Fungal keratitis is diagnosed by an eye doctor through a physical examination and a slit-lamp examination. A sample of the cornea may also be taken for laboratory testing. The doctor may also order imaging tests such as an ultrasound or CT scan to look for signs of infection.

Complications of Fungal Keratitis

Fungal keratitis can cause serious complications, including vision loss, scarring of the cornea, and glaucoma. It can also spread to other parts of the eye, such as the lens or retina, and can cause permanent vision loss.

Prevention of Fungal Keratitis

The best way to prevent fungal keratitis is to practice good hygiene and avoid contact with contaminated objects. People who wear contact lenses should follow the instructions for cleaning and disinfecting the lenses. People with weakened immune systems should take extra precautions to avoid contact with contaminated objects.

What to Look For

If you experience any of the following symptoms, you should seek medical attention immediately:

• Redness in the eye
• Pain in the eye
• Blurred vision
• Sensitivity to light
• Discharge from the eye
• White or gray spot on the cornea

Diagnosis and Treatment

If you experience any of the symptoms of fungal keratitis, you should see an ophthalmologist right away. The doctor will perform a thorough eye exam and may take a sample of the discharge from the eye to test for the presence of a fungus. Treatment for fungal keratitis usually involves the use of antifungal medications, either in the form of eye drops or pills.

Diagnostic Tests for Fungal Keratitis

The diagnosis of fungal keratitis is usually made based on the patient's symptoms and a physical examination of the eye. The doctor may also order additional tests to confirm the diagnosis. These tests may include a slit-lamp examination, corneal scraping, and cultures of the eye discharge.

Slit-Lamp Examination

A slit-lamp examination is a type of microscope that is used to examine the eye. During the examination, the doctor will look for signs of infection, such as inflammation, ulcers, and scarring.

Corneal Scraping

Corneal scraping is a procedure in which a small sample of the cornea is taken and examined under a microscope. This test can help the doctor identify the type of fungus causing the infection.

Cultures of Eye Discharge

Cultures of eye discharge can also be used to identify the type of fungus causing the infection. The sample is taken from the eye and sent to a laboratory for analysis.

Treatment of Fungal Keratitis

Treatment of fungal keratitis depends on the type of fungus causing the infection. Antifungal medications are usually prescribed to treat the infection. In some cases, surgery may be necessary to remove the infected tissue.

Conclusion

Fungal keratitis is a serious eye infection that can lead to vision loss if not treated promptly. Diagnosis of fungal keratitis is important for proper treatment and to prevent further complications. Diagnostic tests such as a slit-lamp examination, corneal scraping, and cultures of the eye discharge can help the doctor identify the type of fungus causing the infection. Treatment of fungal keratitis depends on the type of fungus causing the infection and may include antifungal medications and/or surgery.
