The Temporal Field in Chronic Simple Glaucoma

Periphery kinetic perimetry: clinically feasible to complement central static perimetry

“…In our study, 86% of the glaucoma patients with moderate to severe central visual field defects had corresponding peripheral visual field defects in the forms of localized or diffuse depression of the isopters. Our findings are consistent with the previous studies suggesting that peripheral kinetic perimetry provides additional information to SAP in assessing the remaining visual field, and thus could be used to monitor disease progression in end-stage glaucoma [ 10 , 30 ]. Nowomiejska K et al showed that semi-automated kinetic perimetry (SKP) provides additional information over SAP in patients with end-stage glaucoma (this was observed in 54% cases), as defined by disc appearance (cup-to-disc ratio worse than 0.9) and SAP criteria (MD worse than 20 dB) [ 10 ].…”

Clinical Correlates of Computationally Derived Visual Field Defect Archetypes in Patients from a Glaucoma Clinic

“…Among candidate etiologies, myopia is a particularly interesting possibility; myopia has been previously shown to be associated with nasal retinal nerve fiber layer (RNFL) thinning and temporal VF defects, perhaps mediated by peripapillary atrophy and/or optic disc tilt and torsion. [96][97][98][99][100] In preliminary analysis of spherical equivalent refractive errors similar to that described above for AT4 (temporal wedge defect), patients with AT9 (inferotemporal defect) trended toward being more likely to be myopic in our study cohort. I did not have access to enough fundus images in this study to specifically test for associations with peripapillary atrophy or optic disc tilt and torsion, but these would be worth examining in the future.…”

Differences in visual field loss pattern when transitioning from SITA standard to SITA faster

“…Patterns aligned to the vertical meridian (i.e., temporal and nasal hemianopia) were considered “atypical for glaucoma”. The patterns classified as “possible glaucoma” (temporal wedge, central scotoma, near total loss, and concentric peripheral defect) can be found in glaucomatous VF but are less commonly found than the altitudinal defects and nasal steps that we classified as “typical for glaucoma” 20 , 22 , 23 . The AT compositional weights were summed within each group to derive a compositional weight for the four clinical phenotype groups rather than each of the 16 AT.…”
