We measured the retinal nerve fiber layer thickness (NFLT) in 50 normal eyes and 50 glaucomatous eyes, using a Nerve Fiber Analyzer GDx (GDx). The glaucomatous eyes showed mean deviation of -5dB or greater by Humphrey 30-2 program. We used the following 11 parameters: symmetry, superior ratio, inferior ratio, superior/na-sal, max. modulation, ellipse modulation, with the newly introducted parameters : normalized sup. area, normalized inf. area, elipse standard daviation, disciminant analysis, and sector analysis. When eyes were defined as abnormal if at least one parameter was abnormal, the sensitivity was 86% and the specificity was 54%. These findings show the po-tential usefulness of measurement of NELT using GDx with new parameters in the detection of early glaucoma.
