Question

How does fungal keratitis usually present?

Answer 1

Fungal keratitis presents with symptoms such as eye pain, redness, and vision reduction, and is diagnosed with laboratory tests. It is particularly risky for contact lens wearers due to pathogens thriving between the lens and the cornea, and can lead to blindness if not treated promptly with antifungal medication.

Step-by-step explanation:

Fungal keratitis typically presents as an inflammatory condition of the cornea caused by fungal pathogens. Symptoms may include eye pain, reduced vision, redness of the eye, excessive tearing or discharge, light sensitivity, and a sensation of something in the eye. Diagnosis is often made through clinical examination and confirmed with laboratory tests, including microscopy, culture, or biopsy, to detect the presence of fungal elements.

Contact lens wearers are at increased risk because pathogens like Acanthamoeba can thrive in the space between the contact lens and the cornea. Proper lens hygiene is crucial to prevent this type of infection. In severe cases, if left untreated, fungal keratitis can lead to vision impairment or blindness. Treatment often includes antifungal medication and can sometimes necessitate a corneal transplant.

Answer 2

Fungal keratitis usually presents with symptoms such as eye pain, redness, photophobia, and blurred vision. Improper disinfection of contact lenses is a common cause. Treatment involves antifungal medications.

Step-by-step explanation:

Fungal keratitis usually presents with symptoms such as eye pain, redness, photophobia (sensitivity to light), and blurred vision. The affected eye may also have discharge, swelling, and a feeling of grittiness. In severe cases, the cornea may develop white or gray patches. A common cause of fungal keratitis is improper disinfection of contact lenses or wearing them while swimming.

In order to confirm the diagnosis of fungal keratitis, the doctor may perform a corneal scraping and examine the sample under a microscope. If fungal infection is confirmed, treatment involves the use of antifungal medications, either as eye drops or oral medication, depending on the severity of the infection.
