To compare the retinal nerve fibre layer thickness (RNFLT)/visual field (VF) structure/function relationship with a newly created disc-centred visual field (DCF) and the fovea-centred standard automated perimetry (SAP).
50 eyes with ocular hypertension or open angle glaucoma were enrolled (average MD -9.4 ± 7.0dB, range +1.6 to -25.6dB). SAP was measured with the Humphrey 24-2 (full threshold). DCF was created using the Humphrey Field Analyzer (full threshold) (Figure 1). RNFLT was measured with Stratus optical coherence tomography (OCT). Linear regression between VF log (sector mean sensitivity in linear units) and log RNFLT was performed for each sector and for the whole VF. Residuals of linear regression fits were compared by paired t-tests.
The number of test points and R2 structure/function association values for each sector are shown in Table 1.
