Toxoplasmosis is the most common cause of posterior uveitis in immunocompetent subjects: 30% of the world population may be affected, with wide variability. However, despite high seroprevalence, the incidence of ocular toxoplasmosis (OT) is limited to about 2% of infected patients; thus, about one million patients in France may be estimated to have active or cicatricial OT. Microbiological tools available to the clinician have considerably advanced over the last two decades, allowing the diagnosis of toxoplasmosis to be confirmed in the vast majority of suspected cases. Regardless of the route of infection (congenital or acquired), laboratory confirmation of OT plays a major role in the patient's management, particularly in atypical cases.

D014125 Toxoplasmosis, Congenital Prenatal protozoal infection with TOXOPLASMA gondii which is associated with injury to the developing fetal nervous system. The severity of this condition is related to the stage of pregnancy during which the infection occurs; first trimester infections are associated with a greater degree of neurologic dysfunction. Clinical features include HYDROCEPHALUS; MICROCEPHALY; deafness; cerebral calcifications; SEIZURES; and psychomotor retardation. Signs of a systemic infection may also be present at birth, including fever, rash, and hepatosplenomegaly.

D014126 Toxoplasmosis, Ocular Infection caused by the protozoan parasite TOXOPLASMA in which there is extensive connective tissue proliferation, the retina surrounding the lesions remains normal, and the ocular media remain clear. Chorioretinitis may be associated with all forms of toxoplasmosis, but is usually a late sequel of congenital toxoplasmosis. The severe ocular lesions in infants may lead to blindness.
