“…Identification of central visual field defects is possible using sparse test grids (24-2 and 24-2C), even if a traditional "cluster" criterion cannot be met, which could then signal the clinician to perform additional focussed central testing. 12,13,18,40,41 The 10 extra locations tested by the 24-2C grid are derived from the same Cartesian coordinates of the 10-2 grid.…”

“…Despite the advantages afforded by the higher resolution 10-2 grid, recent studies have offered contrarian views on its additional usefulness compared to the 24-2. 12,13 A question for clinicians is which test to deploy in routine glaucoma assessments, as both central and peripheral tests may provide useful information for the individual patient, depending on their phenotype. Simultaneously performing testing using both grids may be valuable in comprehensively characterising the visual field with the complementary regions of testing.…”

“…IOP was not considered for the diagnosis, and all 21 eyes had gonioscopically open anterior chamber angles. Optic disk damage was evaluated with Spectralis optical coherence tomography (Heidelberg Engineering Inc., Heidelberg, Germany), and visual field examinations were performed using Humphrey automated perimetry (24-2 Swedish Interactive Threshold Algorithm standard [20]; Humphrey Visual Field Analyzer; Carl Zeiss Meditec, Inc., Dublin, CA). This study followed the tenets of the Declaration of Helsinki and was approved by the local Ethical Committee of Biomedical Research.…”

Purpose The use of face mask is globally recommended as a preventive measure against COVID-19. However, the intraocular pressure (IOP) changes caused by face masks remain unknown. The objective of this study was to assess the impact of wearing surgical and FFP2/N95 face masks during a 400-m walking protocol on IOP in primary open-angle glaucoma (POAG) patients. Methods Thirteen subjects diagnosed of POAG (21 eyes) were enrolled in this study. IOP was measured at baseline, during the 400-m walking protocol and after 5 min of passive recovery while POAG patients wore a surgical mask, FFP2/N95 mask and no mask in randomized order. From the 21 POAG eyes, we analyzed the IOP changes caused by physical exercise with two face masks and without wearing any face mask. Results At rest (baseline and recovery measurements), the use of the different face masks did not affect IOP levels (mean differences ranging from 0.1 to 0.6 mmHg). During physical activity, wearing an FFP2/N95 mask caused a small (mean differences ranging from 1 to 2 mmHg), but statistically significant, IOP rise in comparison to both the surgical mask and control conditions (Cohen’s d = 0.63 and 0.83, respectively). Conclusion Face masks must be used to minimize the risk of SARS-CoV-2 transmission, and POAG patients can safely use FFP2/N95 and surgical masks at rest. However, due to the IOP rise observed while walking with the FFP2/N95 mask, when possible, POAG patients should prioritized the use of surgical masks during physical activity.

“…These findings are consistent with previous studies. 13,14 Glaucoma affects both central and midperipheral vision. Patients with CVFDs would have greater impairment in visual function than those with the preserved central VF.…”

“…13 Yet, they have suggested 10-2 to 24-2 testing for detecting progressive paracentral field loss and functional progression, particularly in eyes with any abnormalities within the central 12 points on 24-2 VF. 13,14 The value of detecting a CVFD (defined as the abnormalities within the central 12 points, in the central 10 degrees on 24-2 VF) and related parafoveal scotomas with a 10-2 VF test to document glaucomatous damage to the macula is well recognized. 5,8,15 The macula, the central 8 degrees surrounding fixation, contains ∼40% of all retinal ganglion cells.…”

The severity of central visual field (VF) defects on 24-2 VF and related scotomas on 10-2 VF may be predicted by assessing perimetric defects at abnormal central 12 points on 24-2 VF in early glaucoma.Purpose: Investigating the association between perimetric parameters at abnormal central 12 points on 24-2 VF and the severity of central visual field defects (CVFDs) on 24-2 VF and related parafoveal scotomas on 10-2 VF.Methods: We examined 64 eyes of 56 glaucoma patients with CVFDs on 24-2 VF with a mean deviation better than −7 dB and completed 24-2 and 10-2 VF testing within 6 months. On the basis of 10-2 VFs' pattern defects, eyes were grouped into 3: an arcuate parafoveal scotoma, severe defect; partial arcuate, moderate defect; and minimal defect. VF parameters at abnormal points (P < 1%) within the central-most 4 and paracentral 8 points on total deviation/pattern deviation plots on 24-2 VF were analyzed to predict the severity of CVFDs.Results: Eyes with arcuate scotoma showed more functional loss than eyes without arcuate scotoma on 10-2 VF (P < 0.001). A significant association was observed between abnormal 24-2 VF points' (< 1%) threshold sensitivity lower than 20 dB [odds ratio (OR) = 7.2; P = 0.002 and OR = 5.1; P = 0.003 for the central 4 and paracentral 8 points, respectively] and defect values worse than −15 dB (OR = 8.0 and 5.6 for the central 4 and paracentral 8 points, respectively, P = 0.005) with arcuate scotoma on 10-2 VF. Superior nasal defect in the central 5 degrees on 24-2 VF was significantly associated with an arcuate defect on 10-2 VF (P < 0.001). Conclusion:Clinicians may predict the severity of CVFDs on 24-2 VF and parafoveal scotomas on 10-2 VF by measuring threshold sensitivities and defect values at abnormal central 12 points (< 1%) on 24-2 VF in early glaucoma.
