ABSTRACT
Assessment of the optic nerve head or the retinal nerve fiber layer is essential for the early diagnosis and monitoring of glaucoma. We compared mean retinal nerve fiber layer[RNFL]thickness with Average, and compared RNFL CSA with Integral between Heidelberg Retina Tomograph[HRT] and GDx nerve fiber analyzer[GDx]at global, superior, inferior, nasal and temporal area. Mean RNFL thickness in HRT was significantly greater than Average in GDx at all quadrants[p<0.001], and correlated with Average at global, superior and inferior area[p<0.05]. RNFL CSA in HRT was significantly greater than Integral in GDx at superior, inferior and nasal quadrants[p<0.001], and correlated with Integral at superior and inferior quadrants[p<0.05]. In conclusion, the two parameters related to nerve fiber layer in HRT were measured greater than those in GDx. Correlations of the above parameters between HRT and GDx were mainly present at superior and inferior quadrant. These results may come from regional difference in measurement between HRT and GDx, and uncorrected disc tilting in HRT appears to have adverse effects on the correlations of the above parameters between HRT and GDx at nasal or temporal quadrant.
