[Multiple evanescent white dot syndrome. A diagnostic dilemma].

PURPOSE/METHOD: We present a patient with multiple evanescent white-dot syndrome (MEWDS). On presentation the patient was not initially diagnosed. The diagnosis was established eighteen months later by the clinical, angiographic and electrophysiologic features. We emphasize the difficulties to establish the diagnosis, especially in those cases that like ours present differences with regard to the initial description of the syndrome.

RESULTS/CONCLUSIONS: To establish the diagnosis of MEWDS may be a difficult task because early on presentation it can be misdiagnosed. Because of this, some unnecessary tests may be performed and the patient can receive ineffective treatments and suffer possible side effects.
