title: Changes in optical coherence tomography findings in acute zonal occult outer retinopathy.
abstract: OBJECTIVE
  To report a case of acute zonal occult outer retinopathy (AZOOR) in a 39-year-old woman.
  
  
  METHODS
  Images were obtained with fundus photography and optical coherence tomography (OCT). A multifocal electroretinogram (mfERG) was also obtained to evaluate retinal function.
  
  
  RESULTS
  The patient's right visual acuity was 0.8. Fundus photographs showed no specific abnormal findings. OCT showed attenuation of the photoreceptor inner segment/outer segment (IS/OS) line and the cone outer segment tip (COST) line in the right eye. The mfERG showed corresponding amplitude reductions. One month after the initial visit, her right visual acuity improved to 1.2. There was partial recovery of the IS/OS line; however, the COST line was still absent, and there was no apparent improvement in the mfERG responses.
  
  
  CONCLUSIONS
  Our findings showed a discrepancy between the microstructural findings and visual function during recovery of AZOOR.
