Reactivation of a congenital infection was traditionally thought to be the most common cause of ocular toxoplasmosis, but an acquired infection is now considered to be more common. A toxoplasmosis infection that affects the eye usually attacks the retina and initially resolves without symptoms. However, the inactive parasite may later reactivate causing the ocular presentation of eye pain, blurred vision, and possibly permanent damage, including blindness. Although most cases of toxoplasmosis resolve on their own, for some, inflammation can be treated with antibiotics and steroids.
