What is Chorioretinitis : Causes, Symptoms, Treatment, Diagnosis

What is Chorioretinitis?

Chorioretinitis is an ophthalmological condition characterized by a group of disorders affecting the uvea and the choroid of the eye. The choroid and the uvea form the middle layer of the eye and have in them majority of the blood vessels of the eye. When this area gets inflamed due to any reason then it results in Chorioretinitis.

This inflammation may be serious enough to completely damage or destroy tissues of the eye resulting in significant visual impairment. Chorioretinitis can affect people of all ages but is mostly seen in people between the age group of 25 and 60. Chorioretinitis is mostly seen in people with HIV or with tumors or other infections in the eye. An injury to the eye may also cause Chorioretinitis.

Certain viral infections like the West Nile Virus may also cause Chorioretinitis. Certain medical conditions like multiple sclerosis, Kawasaki Disease, or rheumatoid arthritis also tends to cause Chorioretinitis. Apart from visual impairment, Chorioretinitis can also cause eye pain, sensitivity to light, and excessive tearing. The best way to treat Chorioretinitis is by way of steroids. If a bacterial infection is a suspect then antibiotics is the way to go in treating Chorioretinitis.

How is Chorioretinitis Treated?

The most preferred treatment for Chorioretinitis is steroids. This is usually given in the form of antiinflammatory steroid eyedrops to calm down the inflammation. In some cases, oral steroids or injectable steroid are also given for treatment of Chorioretinitis.
