What is Multiple evanescent white dot syndrome?

The multiple evanescent white dot syndrome (MEWDS) is an inflammatory retinal disorder, typically observed in young patients, that is characterized by unilateral visual loss and the presence of small, punctate, yellow-white lesions that involve the outer retina.

How do you treat white dot syndrome?

White dot syndromes have the potential for causing severe visual loss, but many of the diseases comprising white dot syndromes can be treated. Some are treated by attacking inflammatory pathways, while DUSN is treated by lasering the intraocular nematode.

What are the symptoms of white dot syndrome?

Typically seen in young, otherwise healthy adults, the white dot syndromes most often present with symptoms of photopsia, floaters, decreased night vision, blurred vision, and visual field loss.

How long does multiple evanescent white dot syndrome last?

MEWDS is a self limited disease with excellent visual recovery within 2-10 weeks. However residual symptoms including photopsia may persist for months.

How long does white dot syndrome last?

The white dots may disappear after the first few weeks of the disease. The cause is generally unknown, but a viral illness has been reported prior to MEWDS in one-third of cases.

Does white dot syndrome go away?

Treatment is required in the latter case to combat loss of vision. The white dots usually disappear naturally. Corticosteroids have been shown to speed up this process. The differences in the immune response of each patient may contribute to the differences seen between the white dot syndromes.

What causes white spots on retina?

The white spots (called “drusen”) are deposits of metabolism of the retinal cells. The metabolism weakens as a process of aging and macular cells become damaged. The macula is the part of the retina that is responsible for central fine vision.

What is white dot in eye?

What does white dot syndrome mean?

White dot syndromes are inflammatory diseases characterized by the presence of white dots on the fundus, the interior surface of the eye. The majority of individuals affected with white dot syndromes are younger than fifty years of age. Some symptoms include blurred vision and visual field loss.

What does a spot on the retina mean?

A Roth spot is a hemorrhage, which is blood from ruptured blood vessels. It affects your retina — the part of your eye that senses light and sends signals to your brain that allow you to see. Roth spots are also called Litten’s signs.
