title: [Static fundus perimetry in normals. Microperimeter 1 versus SLO].
abstract: BACKGROUND
  The Microperimeter 1 (MP-1) allows for fundus-controlled static perimetry of the central visual field. The purpose of this study was to compare MP-1 fundus perimetry with the already established scanning laser ophthalmoscope (SLO) fundus perimetry concerning detected threshold values of light increment sensitivity in normals.
  
  
  METHODS
  In 31 eyes of 31 healthy volunteers a fundus controlled static threshold perimetry was carried out each with the MP-1 (Nidek Technologies) and the SLO (Rodenstock). In the central 21 degrees x 12 degrees visual field light increment sensitivity threshold values for 40 corresponding stimulus locations were compared in a rectangular 3 degree-grid.
  
  
  RESULTS
  The average light increment sensitivity was 19.1+/-0.5 dB with the MP-1 and 17.2+/-0.9 dB with the SLO. On average the threshold values of the 40 corresponding test locations were 1.9+/-1.3 dB higher with the MP-1 than with the SLO.
  
  
  CONCLUSIONS
  Both the MP-1 and SLO offer the possibility of a reproducible functional analysis of the central retina under simultaneous fundus control. For comparison of results of the MP-1 and SLO fundus perimetry, a correction factor of approximately 2 dB should be used.
