The present study aimed to assess the ability of en face slab images of maculae to detect residual nerve fiber bundles in eyes with advanced glaucoma.


This study included 36 eyes with diffuse thinning of the ganglion cell and inner plexiform layers (GCL+IPL). Inclusion criterion was GCL+IPL thickness of <1% of the normative database level as detected using optical coherence tomography (OCT). En face slab images (50-μm thickness) were reconstructed from the macular cube scan data using advanced visualization settings. Thereafter, we assessed the agreement of the locations between hyperreflective nerve fiber bundles and normal points in the Humphrey visual field test 10-2 pattern deviation (PD) plots. Additionally, total deviation (TD) corresponding to hyperreflective and hyporeflective areas was compared.


Hyperreflective areas were detected in 31 out of 36 eyes; all 31 eyes exhibited at least one normal PD point despite the substantial GCL+IPL thinning in the macular region. Two eyes with abnormalities in all PD points showed no hyperreflective area. The remaining three eyes had normal PD points despite the lack of high reflectivity areas in the slab images. Therefore, 91.7% of eyes showed agreement between en face slab images and PD plots. Moreover, hyperreflective areas demonstrated significantly better TD than hyporeflective areas.


En face slab images of maculae were able to reveal the residual nerve fiber bundles in the eyes with advanced glaucoma despite the GCL+IPL thickness in the maculae being diffusely and substantially reduced.
