ABSTRACT

PURPOSE: To determine the associations of visual field index (VFI) with advanced glaucoma intervention study (AGIS) score, mean deviation (MD), pattern standard deviation (PSD), and average retinal nerve fiber layer (RNFL) thickness as measured by optical coherence tomography (OCT) and to evaluate the diagnostic abilities of these parameters. METHODS: One hundred fifteen glaucomatous eyes and 78 healthy eyes were enrolled in this cross-sectional study. Each participant had a Humphrey visual field analyzer test and OCT done. The diagnostic abilities of these parameters were analyzed using the receiver operating characteristic (ROC) curve, and we sought to determine the association of these parameters with VFI by Pearson correlation analysis. RESULTS: The associations between analyzed parameters and VFI were statistically significant (all, p<0.001). The area under the ROC curve (AUROC) value of VFI was greater than that of the MD and AGIS score (all, p<0.001) but was not different from the PSD and RNFL average thickness measured by OCT (p=0.756, p=0.638). CONCLUSIONS: The VFI showed significant associations with AGIS score, MD, PSD, and average RNFL thickness as measured by OCT and revealed similar diagnostic abilities as these parameters.

ABSTRACT

PURPOSE: To evaluate and compare correlations between structural and functional loss in glaucoma as assessed by optical coherence tomography (OCT), scanning laser polarimetry (GDx VCC, as this was the model used in this study), standard automated perimetry (SAP), and the Humphrey Matrix (Matrix). METHODS: Ninety glaucomatous eyes identified with SAP and 112 eyes diagnosed using Matrix were independently classified into six subgroups, either S1/M1 (MD>-6dB), S2/M2 (-12

ABSTRACT

PURPOSE: To evaluate the correlation between central corneal thickness (CCT) and retinal nerve fiber layer thickness (RNFLT) as determined by optical coherence tomography (OCT) in glaucomatous subjects. METHODS: One hundred eyes diagnosed with glaucoma and 99 glaucoma suspect (GS) eyes were tested by visual field (VF), OCT, and ultrasonic pachymetry. The relationship between CCT and RNFLT measurements was assessed by Pearson correlation analysis. A mixed effect model was employed to determine the relationship between CCT and RNFLT in glaucoma and GS groups. We divided the patients into two groups depending on the thickness of their corneas: Thin ( or = 553.6 micrometer), and compared three parameters: VF mean deviation (MD), pattern standard deviation (PSD), and RNFLT between the two groups. RESULTS: There were no significant correlations between CCT and RNFLT in any participant (R2=0.00, p=0.88). There was no significant relationship between CCT and RNFLT in glaucoma and GS groups (p=0.11, p=0.46). There were no statistically significant differences in MD, PSD, or RNFLT between the thin and thick cornea groups (p=0.38, 0.32, 0.44). CONCLUSIONS: CCT is not significantly associated with RNFLT in glaucoma and GS subjects.
