It’s an infection of the inner part of the eyes due to a parasite called toxoplasma gondii. It is the most common cause of uveitis. Uveitis is an inflammation of the uvea, which supplies blood to the iris and retina.

About 500 million people are infected with this parasite. It can be congenital or acquired throughout life. Toxoplasmosis can cause vision loss and in some cases even blindness. It can be acquired by contact with unwormed cats, vegetables or fruits that are not washed, and/or poorly cooked meats. It is worth mentioning that there are people who are immune to the parasite because they have the antibodies to fight it.

Ocular toxoplasmosis is an infection whose diagnosis is based on ocular findings and confirmed by blood tests.

Symptoms:

  • Blurry vision
  • Eye pain
  • Light sensitivity

Its treatment is based on the use of antibiotics and corticosteroids for at least one month and depending on the severity of the infection.

In advanced cases, the visual prognosis is reserved due to the location of the damage produced by the parasite in the retina. The retina of the eye is a primary site of infection with this microorganism, so the most common ocular manifestation of toxoplasmosis is chorioretinitis.

Toxoplasmosis is treatable but not curable, which means the parasite can reactivate and continue to cause damage to the inside of the eye. One trigger is stress and anxiety.

Visit your trusted ophthalmologist at least once a year for a comprehensive eye examination.
