title: Recurrent focal choroidal excavation following multiple evanescent white dot syndrome (MEWDS) associated with acute idiopathic blind spot enlargement.
abstract: OBJECTIVE
  To present a recurrent case of conforming focal choroidal excavation (FCE) following multiple evanescent white dot syndrome (MEWDS) in a 25-year-old woman.
  
  
  METHODS
  Following spontaneous MEWDS sings resolution our patient noted a recurrent decrease in vision. Repeated OCT revealed elevation and mild disruption of RPE layer at fovea without previous angiographic MEWDS signs. At this time, short-term systemic steroid therapy was started and visual acuity became normal.
  
  
  RESULTS
  Following quiescence of the new-onset phase, the conforming type of FCE located in inferior macula appeared in OCT. In the following next 2 years recurrence of presumptive focal subfoveal choriocapillaritis occurred for three times presenting with blurred vision. During every acute attack, above-mentioned FCE disappeared and returned back again after resolution of presumptive focal choriocapillaritis.
  
  
  CONCLUSIONS
  This is the first and unique case of recurrent type of FCE following MEWDS. It seems to disappear during active phase of presumptive focal choriocapillaritis and then returns after the eye has become quiescent.
