OBJECTIVE: To evaluate the association between contrast sensitivity (CS), vessel density (VD), and functional parameters in patients with glaucoma of varying severity.
METHODS: Ninety-four eyes of 94 patients (57 men and 37 women, aged 56.52 ± 11.28 years) were divided into mild and moderate to advanced glaucoma groups. The mild glaucoma group was further subdivided based on the presence of central visual field defect (CVFD). Pearson\'s correlations were used to evaluate the associations between area under the log CS function (AULCSF), best-corrected visual acuity (BCVA), 10 - 2 visual field (VF), and structural parameters, including VD. The area under the receiver operating characteristic (AUROC) curve was calculated to detect abnormal CS (AULCSF < 1.2).
RESULTS: In mild glaucoma without CVFD, AULCSF was associated with radial peripapillary capillary VD (γ = 0.597, P = 0.001), with an AUROC of 0.840 (P = 0.006) for detecting abnormal CS. In mild glaucoma with CVFD, AULCSF worsened and was associated with superficial parafoveal VD (γ = 0.569, P = 0.017) and macular whole image VD (γ = 0.632, P = 0.007), with AUROCs of 0.833 (P = 0.021) and 0.792 (P = 0.043), respectively. In moderate to advanced glaucoma, the relationship between AULCSF and the mean deviation of 10 - 2 VF and BCVA was more robust than that observed in structural measures.
CONCLUSIONS: Decreased VD is linked to early CS impairment. Radial peripapillary capillary and macular VD can serve as indicators of CS function in the early stages of glaucoma. KEY  MESSAGES: What is known Contrast sensitivity loss has been reported in glaucoma patients but its relationship with glaucoma-related structural and functional changes in different glaucoma severity and central visual field defect (CVFD) remains elusive. What is new Decline in RPC peripapillary vessel density was associated with early impairment of contrast sensitivity in mild glaucoma without CVFD. Decline in macular vessel density and central 16 points of 10-2 visual field damage were associated with contrast sensitivity reduction in mild glaucoma with CVFD. Microvasculature change can serve as an indicator for abnormal contrast sensitivity.

OBJECTIVE: This study sought to identify the most effective testing program for detecting visual-field defects in mild-stage glaucoma with central visual-field defects.
METHODS: A multicenter, retrospective diagnostic testing evaluation.
METHODS: The study involved 93 eyes (83 patients) with mild-stage glaucoma (median mean deviation [interquartile range]: -1.79 [2.16] dB) with central visual-field defects and 69 eyes (63 patients; median mean deviation, -1.38 [2.31] dB) with mild-stage glaucoma without central visual-field defects, from Jikei University School of Medicine and Tajimi Iwase Eye Clinic.
METHODS: Patients underwent 10-2 Swedish Interactive Thresholding Algorithm (SITA) Standard, 24-2 SITA Standard, and 24-2C SITA Faster tests. Central visual-field defects were defined using 10-2 SITA Standard and optical coherence tomography (OCT). A detection power of 4 points in the 24-2 that coincided with 10-2 (Center4), 12 points that lie within 10° (24-2-12), and 22 points that lie within 10° of 24-2C (24-2C-22) were analyzed using receiver operating characteristic (ROC) curves based on logistic regression analysis, using total deviation (TD) and pattern deviation (PD) probability plots.
METHODS: Area under the receiver operating characteristic curve (AUC) of the Center4, 24-2-12, and 24-2C-22 tests.
RESULTS: In the upper-central visual field, AUCs of the TD plot were 0.50 (0.40-0.58) for the Center4, 0.75 (0.67-0.83) for 24-2-12, and 0.85 (0.78-0.91) for 24-2C-22, with 24-2C-22 AUC significantly exceeding 24-2-12 AUC. For the PD plot, AUCs were 0.53 (0.44-0.63), 0.81 (0.74-0.89), and 0.84 (0.77-0.90), respectively. In the lower-central visual field, using a total plot, AUCs were 0.27 (0.18-0.36), 0.57 (0.47-0.69), and 0.57 (0.46-0.68) for the Center4, 24-2-12, and 24-2C-22, respectively. Using the PD plot in the upper field, AUCs were 0.27 (0.19-0.36), 0.64 (0.53-0.75), and 0.81 (0.72-0.90), respectively, with the AUC of the 24-2C-22 significantly exceeding that of 24-2-12. The 24-2C test was significantly faster than both the 24-2 and 10-2 tests, reducing testing duration by 46% and 52%, respectively.
CONCLUSIONS: The 24-2C SITA Faster test is highly effective and efficient for detecting mild-stage glaucoma with central visual-field defects. This, and its reduced duration, makes it a valuable tool in clinical settings.

OBJECTIVE: To evaluate the relationship between peripapillary tilt and visual field (VF) defects in glaucomatous eyes with axial myopia.
METHODS: Retrospective cross-sectional study.
METHODS: One hundred four eyes of 104 patients with primary open-angle glaucoma (POAG) with myopia were included (52 eyes with high myopia [HM], 26.5 mm ≤ axial length [AL] < 30.0 mm; and 52 eyes without HM, 24.0 mm < AL < 26.5 mm). The direction and magnitude of the peripapillary tilt were evaluated using optical coherence tomography. The eyes were divided into 12 groups according to the tilt directions defined by clock-hour sectors in a clockwise direction in the right eyes and in a counterclockwise direction in the left eyes. The mean deviation (MD) and central VF (CVF) values, ie, the mean threshold values of 4 paracentral points within 5 degrees of the Swedish Interactive Threshold Algorithm 30-2 test, were evaluated.
RESULTS: The direction of the tilt was toward sector 9 (47.1%) and sector 8 (34.6%). The MD and CVF values were significantly worse (P = 0.013 and P = 0.019, respectively) in the sector 9 group than in the sector 8 group. Furthermore, the smaller peripapillary tilt magnitude in the sector 9 group was negatively correlated (P = 0.0019) with the CVF but not with the MD (P = 0.1) among the POAG eyes with HM. In contrast, the ovality index in the sector 9 group was not significantly correlated with the MD (P = 0.4) or the CVF (P = 0.36).
CONCLUSIONS: A smaller temporal peripapillary tilt correlated with CVF defects in POAG eyes with HM. The peripapillary tilt direction and magnitude affect the CVF defect in POAG eyes with HM.

OBJECTIVE: To investigate the characteristics of postoperative central visual field defect (cVFD) in patients with macular hole (MH).
METHODS: Eighteen eyes from 18 MH patients were involved in this retrospective study which reviewed square root of loss variance (sLV) and mean defect (MD) of the visual field test in all subjects. The relationship between cVFD and MH stage, as well as the postoperative ellipsoid zone disruption were evaluated using Spearman\'s correlation test.
RESULTS: Our analysis determined Spearman coefficient is 0.705 for the correlation between sLV and MH stage (P<0.01), 0.877 for the correlation between sLV and postoperative ellipsoid zone disruption (P<0.01) and 0.721 for the correlation between MD and postoperative ellipsoid zone disruption (P<0.01). A significant relationship was also detected between postoperative ellipsoid zone disruption and MH stage (r=0.470, P<0.05). Univariate regression analysis indicated that sLV and MD were associated with postoperative ellipsoid zone disruption (P<0.01, P<0.01, respectively).
CONCLUSIONS: Postoperative cVFD is highly correlated with MH stage and postoperative ellipsoid zone disruption in patients with MH.

OBJECTIVE: To evaluate the characteristic appearance of induced central visual field defects unrelated to the nerve fiber layer on standard automated perimetry using the Swedish Interactive Threshold Algorithm (SITA), and to compare the findings to the appearance on existing Full Threshold (FT) and FASTPAC (FP) algorithms.
METHODS: Thirty right eyes of 30 healthy young participants were examined using four Humphrey 24-2 program algorithms: FT, FP, SITA-Standard (SS), and SITA-Fast (SF). Central visual field defects were induced using a high-density white opacity filter centered on a plano lens. The test duration, fovea threshold, mean sensitivity (MS), mean deviation (MD), pattern standard deviation (PSD), visual field index (VFI), and defect size and depth were compared among all algorithms.
RESULTS: The mean test duration was 21 % to 71 % shorter (p < 0.01), the fovea threshold 0.9 to 2.6 dB higher (p < 0.05), MS 1.1 to 1.7 dB higher (p < 0.05), MD 0.84 to 1.48 dB higher, PSD 0.33 to 0.60 lower, and VFI 2 % higher (p < 0.05) on SS and SF than on FT and FP. The defect size was approximately four points larger and the defect depth 127 to 156 dB shallower on SS and SF than on FT and FP (p < 0.01).
CONCLUSIONS: Central visual field defects unrelated to the nerve fiber layer were wider and shallower and global indices were higher on SITA than on conventional FT and FP. These findings indicate that careful attention is required when converting from FT and FP to SITA.
