title: Optical Coherence Tomography Angiography of Retinal Perfusion in Chiasmal Compression.
abstract: To evaluate the retinal perfusion in patients with chiasmal compression using optical coherence tomography angiography (OCTA).
  
  
  
  Retinal perfusion was evaluated using OCT angiograms in eight eyes of four patients with visual field (VF) defects due to chiasmal compression treated by tumor resection. The retinal perfusion in the area corresponding to the quadrants of the VF defects was investigated in each image. The vessel density was defined as the percentage area occupied by the vessels in the image.
  
  
  
  The decreased peripapillary retinal perfusion correlated with the quadrants of the VF defects on OCT angiograms in all patients. The binarized vessel density decreased, corresponding to the degree of VF defects in all patients.
  
  
  
  A decrease in peripapillary retinal perfusion correlates with the quadrants of the VF defects due to chiasmal compression. This decrease can be noninvasively measured by OCTA. [Ophthalmic Surg Lasers Imaging Retina. 2016;47:724-729.].
