Chorioretinitis is an inflammation of the choroid (thin pigmented vascular coat of the eye) and retina of the eye. It is a form of posterior uveitis. If only the choroid is inflamed and not the retina, the condition is termed choroiditis.[1] The ophthalmologist's goal in treating these potentially blinding conditions is to eliminate the inflammation and minimize the potential risk of therapy to the patient.

Symptoms[edit]

Symptoms may include the presence of floating black spots, blurred vision, pain or redness in the eye, sensitivity to light, or excessive tearing.[2]

Causes[edit]

Ophthalmoscopic findings during vitrectomy. The video shows the whitish cloudy cords and the white retinal spots found during vitrectomy. In a case of placoid chorioretinitis due to Treponema pallidum.

Chorioretinitis is often caused by toxoplasmosis and cytomegalovirus infections (mostly seen in immunodeficient subjects such as people with AIDS or on immunosuppressant drugs).[3] 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 syphilis, sarcoidosis, tuberculosis, Behcet's Disease and onchocerciasis.

Treatment[edit]

It is treated with a combination of corticosteroids and antibiotics. If there is an underlying cause such as AIDS, specific therapy can be started as well.
