Unspecified disseminated chorioretinal inflammation: Understanding the Condition

Unspecified disseminated chorioretinal inflammation is a rare eye condition that affects the retina and choroid, which are the two main layers of the eye. The condition is also known as multiple evanescent white dot syndrome (MEWDS) and is characterized by the appearance of small, white dots in the retina and choroid.

The exact cause of MEWDS is unknown, but it is believed to be an autoimmune condition, where the body's immune system attacks the retina and choroid. MEWDS usually affects young adults, and women are more commonly affected than men.

Symptoms of Unspecified Disseminated Chorioretinal Inflammation

The symptoms of MEWDS include:

  1. Blurred vision
  2. A blind spot in the central vision
  3. Flashing lights or floaters in the vision
  4. Loss of vision in one eye
  5. Eye pain or discomfort

The symptoms of MEWDS can be severe, but they usually improve over time. In some cases, vision may return to normal within a few weeks or months. However, in some rare cases, MEWDS can lead to permanent vision loss.

Treatment for Unspecified Disseminated Chorioretinal Inflammation

There is no specific treatment for MEWDS, but in most cases, the condition resolves on its own within a few months. However, some medications, such as corticosteroids, may be prescribed to reduce inflammation and hasten recovery.

Regular eye exams are recommended for individuals who have been diagnosed with MEWDS to monitor the progression of the condition and ensure that vision is not further compromised.


Unspecified disseminated chorioretinal inflammation is a rare eye condition that affects the retina and choroid. While there is no cure for the condition, most individuals experience a full recovery within a few months. If you are experiencing any of the symptoms associated with MEWDS, it is important to seek medical attention promptly to ensure that you receive an accurate diagnosis and appropriate treatment.
