Correlation between the ganglion cell complex and functional measures in glaucoma patients and suspects.

The purpose of the study was to correlate the Fourier-domain OCT ganglion cell complex (GCC) parameters with automated perimetry (AP) functional measures of the optic nerve. This retrospective study included patients who had previously undergone examination with the RTVue-100 OCT and AP, SITA strategy. The parameters of GCC (average, superior, inferior, S-I [superior inferior difference], S-I SD [standard deviation of S-I], GLV [global loss volume] and FLV [focal loss volume]) were correlated with the mean deviation (MD) and pattern standard deviation (PSD) values of AP using linear and logarithmic regression analysis.

Correlation between the ganglion cell complex and structural measures of the optic disc and retinal nerve fiber layer in glaucoma.

To correlate the ganglion cell complex (GCC) parameters with structural measures of the optic nerve head (ONH) and retinal nerve fiber layer (RNFL) as evaluated by Fourier-Domain optic coherence tomography (OCT). This retrospective study included patients with glaucoma, ocular hypertensive patients and glaucoma suspects who had previously undergone OCT examination with the RTVue-100. The parameters of GCC (average, superior, inferior, focal loss volume [FLV], global loss volume [GLV]) were correlated with the values of the ONH (cup volume, cup area, horizontal cup-to-disk ratio, vertical cup-to-disk ratio, and rim area) and RNFL (average, superior, and inferior) using Pearson's correlation coefficient.
