How GDxPRO measures RNFL Integrity


GDxPRO measures RNFL structural organization
  • SLP passes polarized light through the RNFL and creates a high resolution map from over 32,000 data points.
  • A phase shift occurs because light polarized parallel to RNFL micro-structures travels more slowly than light polarized perpendicular to them.
  • The size of this shift, termed RNFL Integrity, depends upon both the thickness of the RNFL and the cumulative level of organization of its micro-structures.
