title: [Objective retinal nerve fiber laser assessment by scanning laser polarimetry in patients with chiasmal compression].
abstract: OBJECTIVE
  To assess the evaluation ability of retinal nerve fiber layer (RNFL) in patients with visual tracts' compression and to assess the correlation between visual field loss and changes in RNFL.
  
  
  METHODS
  Polarimetric RNFL analysis (scanning laser polarimeter- NFA/GDx, software version 1.0.16, LDT(inc)) and kinetic perimetry were done in 41 eyes with different types of optic chiasma compression and in 40 healthy eyes, age matched controls.
  
  
  RESULTS
  In eyes with optic chiasma compression most of the GDx parameters were statistically different from the control group (P<0.05). In eyes with normal visual fields and with optic chiasma compression most of GDx parameters were statistically different from the other analyzed groups.
  
  
  CONCLUSIONS
  GDx may be a helpful tool in diagnosis of optic chiasma diseases. GDx is a useful visual prognostic indicator in the preoperative assessment of optic chiasma compression. Objective RNFL assessment is especially important in patients with serious visual field loss and poor visual acuity.
