What Is a Fungal Eye Infection?

A fungal eye infection occurs when fungi invade the cornea or internal eye structures. The corneal form, called fungal keratitis, is more common and often linked to eye injury involving plant material or contaminated lenses. Severe cases can affect deeper tissues inside the eye. Symptoms include redness, pain, tearing, and reduced clarity. These infections require prompt medical care to prevent lasting damage.

What Causes a Fungal Eye Infection?

Fungal infections often develop after trauma involving soil, wood, or plant matter. Contact lens wearers can be exposed if lenses or solutions become contaminated. Certain fungi thrive in warm, humid environments and can enter through small scratches. People with weakened immune systems are more vulnerable. Early detection helps limit complications.

Common Symptoms of Fungal Eye Infection

Fungal involvement usually produces noticeable signs.

  • Redness, pain, and tearing.
  • Light sensitivity.
  • White or gray corneal infiltrates.
  • Slow-developing symptoms compared with bacterial infections.
  • Blurred vision as the infection progresses.

How Is a Fungal Eye Infection Diagnosed?

Doctors examine the cornea using a slit lamp to look for patterns linked to fungal growth. They may scrape the cornea to obtain a sample for lab testing. Imaging helps assess deeper involvement. Medical history, trauma details, and lens hygiene habits guide diagnosis. Early identification supports more targeted treatment.

How Is a Fungal Eye Infection Treated?

Treatment involves antifungal drops, oral medication, or both. Some cases require injections near the eye to control deeper infection. Severe corneal damage may need surgery to remove infected tissue. Follow-up visits track healing and look for recurrence. Quick medical attention limits long-term impact.
