Purpose
To measure retinal nerve fiber layer thickness (RNFL) in patients with anterior ischemic optic neuropathy (AION) by scanning laser polarimetry and to asses the correlation between RNFL thickness and perimetric indices in AION eyes.

Material and methods
Polarimetric RNFL analysis (scanning laser polarimeter- NFA/GDx, software version 1.0.16, LDTinc) and standard automated perimetry (SAP- HFA, 24-2 thresold test) was done in 28 AION eyes and in 14 healthy age matched controls.

Results
In AION eyes most of the GDx parameters were statistically different from the control group (P<0.05). Some of the GDx parameters strongly correlated with SAP indices (MD) in AION eyes.

Conclusions
RNFL thickness measured with NFA/GDx is thinner in AION eyes than in healthy eyes and correlates with visual field loss.
