PARASITIC KERATITIS 

A Parasite is an organism that lives off another organism, for example, Acanthamoeba; this organism is usually in water bodies, soil, hearing, ventilating, and air conditioner units.

Keratitis caused by a parasite is called Acanthamoeba keratitis.

WHAT IS ACANTHAMOEBA KERATITIS?

Acanthamoeba keratitis is a rare infection that occurs when Acanthamoeba organisms from contaminated water or contact lens solutions enter the eye through tiny scrapes caused by contact lens wear or other minor injuries to the eye, the parasite Acanthamoeba is one-celled and surprisingly very common in nature; when it infects the cornea (outer transparent layer of the eyes), it results in an eye infection that can cause vision loss or blindness if left untreated.

SYMPTOMS OF ACANTHAMOEBA KERATITIS

• Sensation of something in the eye
• Eye pain and redness
• Blurred vision
• Sensitivity to light (Photophobia)
• Excessive tearing

RISK FACTORS OF ACANTHAMOEBA KERATITIS

Acanthamoeba keratitis can develop in anyone who gets in contact with contaminated water; contact lens wearers are more prone to this infection as certain practices increase the risk of infection. They may include:

• Sharing contact lenses
• Poor storage/ use of contact lenses
• Swimming while wearing contact lenses
• Eye injuries
• Use of contaminated water

DIAGNOSIS OF ACANTHAMOEBA KERATITIS

An optometrist diagnoses this condition after evaluating the symptoms and growth of the parasite; early diagnosis is essential to prevent complications from occurring and for effective treatments.

TREATMENT OF ACANTHAMOEBA KERATITIS

Treatment usually requires aggressive medical and surgical intervention; it involves a combination of prescribed medications such as antibiotics and anti-fungal. Consult an Optometrist to determine the best treatment options because the severity of infections may vary per individual.
