Various types of pathogens can affect the eyes and lead to an infection. Although fungal infections are much less common than bacterial and viral eye infections, they can be very severe. Fungal eye infections can lead to permanent vision problems, including blindness. September 23rd marks the start of Fungal Disease Awareness Week and it’s an excellent time to learn more about fungal eye infections and how to prevent them. |
Symptoms
- Discharge from the eye
- Blurred vision
- Eye pain
- Excess tearing
- Sensitivity to light
- Redness
The symptoms above are similar to other infections, such as those caused by a virus or bacteria. At first glance, a doctor may not know the cause of an eye infection. That’s why it’s critical to see an eye doctor as soon as symptoms start, so tests can confirm the type of infection present.
Types of fungi that cause eye infections
- Aspergillus: This is a common fungus that lives in all kinds of environments and can be contracted indoors or outdoors.
- Candida: Candida is a type of yeast in the mucous membranes of the body. It is typically harmless and does not lead to infections. But when an overgrowth of yeast develops, it can become problematic.
- Fusarium: Fusarium is a fungus that is found outside, particularly in plants or soil.
Any one of the above fungi can lead to an eye infection. Possible infections include keratitis, which involves the cornea. Keratitis can either be superficial and only infect the outer layers of the cornea or affect the deeper layers. Another possible infection is endophthalmitis, which infects the inside of the eye.
Who gets fungal eye infections?
Diagnosis
To make a diagnosis, the doctor takes a medical history and performs an eye exam. A tiny sample of fluid or tissue from the eye may be taken to send to a lab for analysis. The specimen is examined or cultured to check for the presence of fungus. Once a definitive diagnosis is made, proper treatment can start.
Treatment
In more significant infections, oral antifungal drugs may be administered. If a person’s condition prevents them from taking oral medications, antifungal drugs can also be delivered through a vein or directly into the eye. Severe fungal infections that do not respond to medication may require surgery.
Prevention
- Wear swim goggles when swimming in a fresh body of water to prevent the fungus from getting into the eyes.
- When working with plants, soil, or on a farm, wear protective eyewear to avoid an eye injury.
- If you wear contacts, be sure to always wash your hands before handling your lenses.
