| Summary: |
Purpose: 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.
Material and methods: Polarimetric RNFL analysis (scanning
laser polarimeter- NFA/GDx, software version 1.0.16,
LDTinc) 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. |
