Structure-Function Relationship in Glaucoma Using Spectral-Domain Optical Coherence Tomography

Estimating Visual Field Mean Deviation using Optical Coherence Tomographic Nerve Fiber Layer Measurements in Glaucoma Patients

“…We demonstrated that this NFL weighted logarithmic average, compared to a simple logarithmic transform of the NFL average thickness, was better correlated with VF_MD. This result is consistent with the finding by some investigators that the correlation between VF and NFL is higher for sectors averages than overall average 18,27 .…”

Structure–function relationship among three types of spectral‐domain optical coherent tomography instruments in measuring parapapillary retinal nerve fibre layer thickness

“…This study (mean MD = −8.9 dB) included more eyes with severe visual field loss than Rao’s study (mean MD = −2.8 dB). As mentioned above, the base level was estimated at more than 60% of the average RNFL thickness by the three instruments, which was in the same line with Rao et al.’s reports (Rao et al. 2011).…”

Residual and Dynamic Range of Retinal Nerve Fiber Layer Thickness in Glaucoma: Comparison of Three OCT Platforms

“…23,24 Linear models of the relationship between cross-sectional SDOCT RNFL and SAP data have indicated that RNFL layer thickness measurements reach the lower end of their dynamic range while there is still remaining function. 13,25 This is corroborated by our findings that average RNFL thickness measured with Cirrus, Spectralis, and RTVue reached the floor at relative VF sensitivities of À10.4, À14.0, and À14.4 dB, respectively. In other words, since the relative VF sensitivity ranges between 0 dB (no loss corresponding to low-contrast stimulus, i.e., in healthy subjects) and approximately À35 dB (complete loss corresponding to high-contrast stimulus), 70.3%, 60.3%, and 58.9% of global function still remained at the time RNFL reached the measured floor.…”
