How can you tell the difference between retinitis and Choroiditis?

Retinitis appears as a whitish patch with ill-defined borders. It is superficial, with severe overlying vitritis. In contrast, choroiditis lesions appear as yellow patches, with regular borders, deeper to the retinal vessels, causing mild vitritis.

What is toxoplasmosis Chorioretinitis?

Toxoplasma chorioretinitis, more simply known as ocular toxoplasmosis, is possibly the most common cause of infections in the back of the eye (posterior segment) worldwide. The causitive agent is Toxoplasma gondii, and in the United States, most cases are acquired congenitally.

Can toxoplasmosis cause Vitritis?

Ocular toxoplasmosis most often presents as a focal necrotizing retinitis. It is generally associated with vitritis and often with anterior uveitis. Less commonly, it may present as a papillitis.

What is CMV retinitis?

Cytomegalovirus (CMV) retinitis is a viral infection of the retina of the eye resulting in inflammation. Cytomegalovirus is a large herpes-type virus commonly found in humans that can cause serious infections in people with impaired immunity.

Does Chorioretinitis cause blindness?

Chorioretinitis is inflammation of the retina and choroid of the eye and is a type of uveitis. The condition is typically caused by a bacterial, parasitic or viral infection. Chrorioretinitis can cause vision loss and even blindness if not treated promptly and properly by an eye doctor.

Does CMV cause Chorioretinitis?

In immunocompetent children, chorioretinitis is usually associated with congenital infection; acquired infection is a less likely cause. T gondii and CMV are the leading causes of congenital infections associated with chorioretinitis.

Can toxoplasmosis cause blindness?

A toxoplasmosis infection that affects the eye usually attacks the retina and initially resolves without symptoms. However, the inactive parasite may later reactivate causing eye pain, blurred vision, and possibly permanent damage, including blindness.

Does toxoplasmosis cause uveitis?

Ocular toxoplasmosis is the most common cause of infectious posterior uveitis, and the diagnosis is made by clinical findings in the majority of the cases.

What does CMV do to eyes?

CMV retinitis is an infection that attacks the light-sensing cells in the retina. It is a serious disease that should be diagnosed and treated immediately, because it can lead to loss of vision, and in the worst cases, blindness.

Is CMV retinitis curable?

The anti-viral drugs commonly used to treat CMV retinitis are ganciclovir (Cytovene), foscarnet (Foscavir) and cidofovir (Vistide). They can slow down the progression of CMV, but they can’t cure it.
