title: The outer Bruch membrane layer: a previously undescribed spectral-domain optical coherence tomography finding.
abstract: OBJECTIVE
  To report a previously undescribed spectral-domain optical coherence tomography finding, the outer Bruch membrane layer.
  
  
  METHODS
  Prospective case descriptions.
  
  
  RESULTS
  Patients with variable macular abnormalities were examined with spectral-domain optical coherence tomography scanning. All had areas of either retinal pigment epithelial elevation or atrophy with an underlying hyperreflective band that we interpret as the outer Bruch membrane layer.
  
  
  CONCLUSIONS
  The outer Bruch membrane is a consistent optical coherence tomography finding in areas of absent, atrophic, or elevated retinal pigment epithelium.
