title: [Confocal scanning laser Doppler retinal flowmetry in normal eyes].
abstract: OBJECTIVE
  To introduce a new noninvasive equipment to measure the blood flow of optic nerve head and retina.
  
  
  METHODS
  The scanning laser Doppler retinal flowmeter (Heidelberg Engineering, Heidelberg, Germany) was used to measure the blood flow of optic nerve head and retina of 82 eyes of 48 normal individuals.
  
  
  RESULTS
  The average blood flow volume, blood flow velocity and the erythrocyte flow velocity of the vessel in optic nerve head were 203.14 +/- 74.77, 6, 272.43 +/- 2,260.07, 13.14 +/- 2.58 respectively; they were 26.36 +/- 14.74, 467.99 +/- 270.15, 1.93 +/- 1.07 in lamina cribrosa; 22.90 +/- 11.32, 514.53 +/- 370.21, 1.69 +/- 1.12 in the temporal rim of papilla; 21.77 +/- 9.83, 493.21 +/- 290.29, 1.65 +/- 0.90 in nasal rim of papilla; 32.55 +/- 13.00, 558.63 +/- 293.45, 1.78 +/- 0.83 in the temporal juxtapapillary retina; 20.61 +/- 8.92, 358.64 +/- 212.66, 1.20 +/- 0.66 in the nasal juxtapapillary retina; 28.89 +/- 11.52, 497.97 +/- 278.70, 1.64 +/- 0.83 in the avascular area of temporal retina; 25.00 +/- 8.04, 455.87 +/- 203.65, 1.55 +/- 0.64 in the avascular area of nasal retina.
  
  
  CONCLUSIONS
  Confocal laser scanning Doppler retinal flowmetry, which is based on confocal laser scanning technology and Doppler flowmetry, is an effective clinical method to determine the blood flow in optic nerve head and retina.
