Chorioretinitis is an inflammatory process of the choroid which is caused by toxoplasmosis and cytomegalovirus infections. This eye condition affects young children or immunocompromised subjects, such as people with AIDS. Congenital toxoplasmosis via transplacental transmission can also lead to sequelae such as chorioretinitis along with hydrocephalus and cerebral calcifications. Other possible causes of chorioretinitis are bacterial and protozoal infections. The choroid is a vascular layer of the eyeball, located between the retina and sclera, and since it lines and supplies the retina, a chorioditis triggers a retinitis, hence the name of this condition: chorioretinitis.
Symptoms of chorioretinitis are blurry vision, the presence of black spots, pain, redness in the eye, and excesive tears. As a treatment for this eye disease, a combination of corticosteroids and antibiotics is used. If there is an underlying cause such as AIDS, specific therapy can be started as well.
