Background/aimsTo compare the structure–function relationship between compass microperimetry (CMP; CenterVue, Padova, Italy) and Humphrey field analyser (HFA; Carl Zeiss Meditec, Dublin, California, USA) in open-angle glaucoma (OAG) eyes with myopia.MethodsCircumpapillary retinal nerve fibre layer thickness (cpRNFLT) and visual field (VF) mean sensitivity (MS) were obtained in 90 OAG subjects using the optical coherence tomography, CMP and HFA in a random order. The global and sectoral structure–function relationships between the cpRNFLT and VFMS were assessed with different VF devices (CMP vs HHA) in OAG eyes with and without myopia.ResultsOverall, the global and regional structure–function relationships between the two devices did not show significant differences except for the superotemporal sector. In the myopic subgroup, the global association between the average cpRNFLT and VFMSCMP was significantly stronger than that between the average cpRNFLT and VFMSHFA (r=0.806 vs. 0.720, p=0.035). The presence of myopia and higher global cpRNFLT were significantly associated with the greater global VFMS differences between the two devices (p<0.05).ConclusionIn general, structure–function relationship is similar between CMP and HFA in OAG eyes. However, the global structure–function relationship is significantly stronger with CMP than with HFA in OAG eyes with myopia.

Abstract Uveitis is the most common inflammatory ocular disorder and frequently complicated by glaucoma, which is an important cause of irreversible sight loss. Inflammatory nature of the disease and widely fluctuating of intraocular pressure may affect visual function in patients with uveitis complicated by glaucoma. Therefore, we investigated the structure − function relationship and vision-related quality of life (VR-QoL) in 69 patients with uveitic glaucoma (UG), compared with 138 patients with primary open-angle glaucoma (OAG) using 25-item National Eye Institute Visual Function Questionnaire (VFQ-25). In a generalized linear model including age and corresponding structural metrics, the UG eyes had significantly lower mean deviation (MD) of the whole visual field (VF) and superior VF than the OAG eyes (p = 0.012 and 0.040). Patients with UG showed significantly lower composite score and 5 subscales of the VFQ-25, compared with those with OAG (p < 0.05, for all). In the OAG group, the composite score showed strongest associations with the whole binocular integrated VF (β = 1.156, p < 0.001), whereas in the UG group, a significant association was seen only with the inferior VF of the affected eye (β = 0.747, p = 0.005). In conclusion, eyes with UG exhibited a distinctive structure–function relationship and worse VR-QoL that differentiated them from OAG eyes.

Abstract Purpose To compare the blood flow situation in primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (PXG) using optical coherence tomography angiography (OCTA). Methods In this prospective study a total of 26 POAG and 23 PXG eyes were included. All patients underwent a complete ophthalmological examination including standard automated perimetry, stereoscopic photographs of the optic disc, peripapillary retinal nerve fibre layer analysis and examination of vascular parameters of the optic nerve head (ONH), the peripapillary region and macula using OCTA. In addition to the vascular parameters recorded by the device, the vascular images were graphically evaluated using Image J. All recorded vascular parameters were compared between both groups and correlated to structural and functional parameters. Results The mean superficial perifoveal plexus perfusion density (PD) was significantly lower in PXG eyes than compared to POAG eyes using OCTA (32.57% ± 3.57% vs. 34.92% ± 2.11%, p = 0.007). The mean PD parameters for the superficial peripapillary plexus (40.98% ± 3.04% vs. 42.09% ± 2.29%, p = 0.152) as well as the size of the foveal avascular zone (FAZ) (0.23 mm2 ± 0.1 mm2 vs. 0.23 mm2 ± 0.09 mm2) did not differ between both groups. Additional graphic evaluation using Image J showed no significant difference for superficial perifoveal plexus PD (32.97% ± 1.11% vs. 33.35% ± 0.95%, p = 0.194) and peripapillary plexus PD (46.65% ± 0.83% vs. 46.95% ± 0.5%, p = 0.127) between the groups. Retinal nerve fibre layer (RNFL) thickness correlated significantly with peripapillary plexus PD for both OCTA data and Image J data (p < 0.001, p = 0.032). Conclusion The severity of the glaucoma seems to be crucial for peripapillary and macular perfusion densities, and not the form of glaucoma. An additional graphic evaluation is a possible step that could be implemented to improve the comparability of OCTA scans and to optimize the possibility of quantitative perfusion analysis in the case of deviating quality criteria.
