Multiple evanescent white dot syndrome (MEWDS) can be characterized using multifocal electroretinogram (MFERG). MFERG abnormalities in MEWDS patients resolved with clinical symptom resolution.

Area of Science:

  • Ophthalmology
  • Neuroscience

Background:

  • Multiple evanescent white dot syndrome (MEWDS) is an idiopathic inflammatory condition affecting the outer retina.
  • Diagnosis typically relies on characteristic clinical findings and fluorescein angiography.

Observation:

  • A case study of a 22-year-old female presenting with acute monocular scotomata post-upper respiratory infection.
  • Fluorescein angiography confirmed findings consistent with MEWDS.

Findings:

  • Multifocal electroretinogram (MFERG) revealed localized areas of signal depression corresponding to scotomata.
  • These MFERG abnormalities resolved within 6 weeks, correlating with clinical symptom improvement.

Implications:

  • MFERG offers a more localized assessment of retinal function in MEWDS compared to full-field ERG.

  • MFERG may be a valuable diagnostic and monitoring tool for MEWDS and similar visual field-enlarging syndromes.
