The cause of MEWDS (Multiple Evanescent White Dot Syndrome) is idiopathic inflammation of the retina and choroid.
Understanding MEWDS Etiology
While the exact cause remains unknown (idiopathic), here's what we understand based on available information:
- MEWDS is characterized by inflammation affecting the retina and choroid layers of the eye.
- It primarily affects healthy, young, myopic females.
- The presentation is typically acute and unilateral (affecting one eye).
- A preceding viral illness is reported in approximately one-third of cases.
Contributing Factors: What We Know
Although the definitive cause is unknown, these factors are commonly observed in MEWDS cases:
- Age and Gender: Young females are more susceptible.
- Refractive Error: Myopia (nearsightedness) is a common finding.
- Prior Viral Infection: A significant portion of patients report a viral illness preceding the onset of symptoms.
Summary of MEWDS Causes
| Factor | Description |
|---|---|
| Primary Cause | Idiopathic inflammation of the retina and choroid |
| Demographics | Young, healthy, myopic females |
| Laterality | Typically unilateral |
| Associated Condition | Preceding viral illness (in about 1/3 of cases) |
