Multifocal choroiditis

What causes multifocal choroiditis?

Multifocal choroiditis occurs spontaneously and the cause is not currently known (idiopathic). It is possible that a bacterial or viral infection may trigger an immune response that causes the inflammation seen with MFC, though more research is needed in this area.

How is multifocal choroiditis diagnosed?

Multifocal choroiditis (MFC) is diagnosed by an ophthalmologist, using a series of imaging techniques. A test called flourescein angiography uses a special dye and camera to study blood flow in the back layers of the eye. When a person has MFC, lesions in the eye will appear as fluorescent spots. Vision tests may also show an enlarged blind spot or a decrease in visual clarity. Often, doctors may order blood tests to check if the symptoms are caused by a viral disease rather than MFC.

What is the long-term outlook for multifocal choroiditis?

The long-term outlook (prognosis) for multifocal choroiditis (MFC) differs case by case. Symptoms often recur after treatment in one or both eyes, but the frequency and severity varies. Some people maintain normal vision throughout the course of the disease, while others may experience complications that cause more severe vision loss. It is recommended that people with MFC have their eyes checked frequently by an ophthalmologist to monitor symptoms and disease progression.

How might multifocal choroiditis be treated?

Multifocal choroiditis (MFC) is generally treated with steroid medication that can be taken orally or injected into the affected eye. These treatments may be successful in managing symptoms, though there is no permanent cure for the disease and symptoms may return. If a person no longer responds to steroid treatment, drugs that suppress the immune system, such as cyclosporine, may be recommended. People with more severe vision loss may also benefit from laser therapy. Frequent monitoring by an ophthalmologist is recommended to determine how well treatment is working.
