title: Visualization of the Retinal Vasculature Using Wide-Field Montage Optical Coherence Tomography Angiography.
abstract: OBJECTIVE
  To evaluate the technique of wide-field montage optical coherence tomography angiography (OCTA) for improved visualization of the retinal vasculature in the posterior pole.
  
  
  METHODS
  In this prospective case series, five eyes (three healthy and two diseased) of three patients were imaged using a novel technique to create wide-field montage OCTA images by combining nine 3 × 3-mm OCTA scans from the prototype AngioVue software of the RTVue XR (Optovue, Fremont, CA). Features seen on montage OCTA were compared to those visualized on fluorescein angiography (FA) and single-scan 8 × 8-mm OCTA.
  
  
  RESULTS
  The montage OCTA showed the retinal vasculature in the greatest detail. The technique successfully detected vascular abnormalities seen on FA, and in some instances, montage OCTA visualized pathology that was not detected by FA and 8 × 8-mm OCTA.
  
  
  CONCLUSIONS
  Wide-field montage OCTA imaging is a noninvasive, high-resolution technique to improve visualization of the retinal vasculature in the posterior pole.
