RESUMEN
PURPOSE: To describe a patient who fulfilled the criteria for both clinically definite multiple evanescent white dot syndrome (MEWDS) and multiple sclerosis. METHODS: We performed a complete ophthalmologic and neurological examination in a 30-year-old woman who was referred to our department for blurred vision in her left eye (LE) with photopsia. RESULTS: Following a complete ophthalmologic examination, the patient was diagnosed with MEWDS and coincident multiple sclerosis. She underwent therapy with intravenous methylprednisolone (1000 mg/day) for three days, followed by oral prednisone (1 mg/kg per day) for 15 days. Most of the symptoms and signs apparently regressed within one month, despite a still abnormal OCT macular scan, probably due to atrophic post-inflammatory changes in the outer and photoreceptor layers (rods and cones). CONCLUSION: This report, showing the clinical features of MEWDS associated with multiple sclerosis, strongly suggests common neuropathological and inflammatory mechanisms between MS and white dot syndromes.
