PURPOSE: To investigate if the structure-function relationship between circumpapillary retinal nerve fibre layer (cpRNFL) thickness and visual field (VF) thresholds is stronger when using the Goldmann V target rather than the Goldman III target where glaucomatous damage is advanced.
METHODS: Optical coherence tomography (OCT) and VF (Humphrey Field Analyzer 24-2 or 30-2) measurements with Goldmann III (SITA standard) and V (full-threshold) targets were carried out in 51 eyes of 51 patients with primary open angle glaucoma. The relationship between cpRNFL thicknesses in supero- and infero-temporal sectors, and VF sensitivity with the Goldmann III or V target was investigated.
RESULT: Visual field sensitivities (dB) both with the Goldmann III target and Goldmann V target showed a floor effect in the structure-function relationship against cpRNFL thickness, at approximately 60 μm. There was no significant relationship between visual field sensitivity measured with the Goldmann V target (dB scale: p = 0.12, 1/Lambert scale: p = 0.40; linear mixed models) and cpRNFL thickness, when corresponding visual field sensitivity, measured with the Goldmann III target, was <20 dB.
CONCLUSION: There was no improvement in the structure-function relationship using the Goldmann V target (full-threshold), compared to using the Goldmann III target (SITA standard), where glaucomatous damage was advanced.
