Purpose To investigate if the structure‐function relationship between circumpapillary retinal nerve fibre layer (cp RNFL ) 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 cp RNFL 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 cp RNFL 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 cp RNFL 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.
