A man in the United States (US), experienced a nightmarish ordeal that caused him to go partially blind. Acanthamoeba keratitis, a severe infection that affects the cornea and may cause irreversible vision loss, is said to have spread to the man’s eye.
What is Acanthamoeba keratitis?
Acanthamoeba keratitis is a rare but serious eye infection caused by the amoeba Acanthamoeba, which is commonly found in soil, water, and air. This infection can affect anyone, but it is most commonly seen in people who wear contact lenses.
Symptoms of Acanthamoeba keratitis may include:
- Eye pain
- Redness and inflammation of the eye
- Blurred or hazy vision
- Sensitivity to light
- Excessive tearing or discharge from the eye
- The feeling of something in the eye.
If left untreated, Acanthamoeba keratitis can lead to permanent vision loss or even blindness.
Treatment for Acanthamoeba keratitis
The treatment typically involves the use of prescription eye drops or ointments that contain specific antimicrobial agents that can kill the amoeba. In some cases, oral medications may also be prescribed. Treatment can be lengthy, often taking several months to clear the infection. Surgery may also be necessary in severe cases which may include penetrating keratoplasty (PK). A PK is a full-thickness corneal transplant. A cornea from a donor replaces your damaged cornea.
How to prevent Acanthamoeba keratitis?
It is essential to maintain good hygiene when handling contact lenses. This includes:
- Washing your hands thoroughly before handling lenses
- Using fresh contact lens solution every day
- Avoid using tap water to rinse lenses or lens cases.
- Remove contact lenses before swimming or using a hot tub.
- Never sleep while you have your contacts on
Additionally, it is important to have regular eye exams to detect any early signs of infection. Consult your healthcare provider at the first signs of eye pain, redness or sensitivity. Don’t wait until you experience vision loss.
