Factors Related to Superior and Inferior Hemifield Defects in Primary Open-Angle Glaucoma

Figure 1

(a) A representative eye with glaucoma with superior hemifield defects measured by spectral-domain optical coherence tomography (SDOCT). Circumpapillary retinal nerve fiber layer (cpRNFL) thickness map (left) and macular ganglion cell complex (mGCC) thickness map (right). ST: superior-temporal; TU: temporal-upper; TL: temporal-lower; IT: inferior-temporal; IN: inferior-nasal; NL: nasal-lower; NU: nasal-upper; SN: superior-nasal. (b) Evaluation of the central visual field defect. The VF defects correspond to the cpRNFL and mGCC maps at the top panels. In the pattern deviation plot of the visual field measured by the Humphrey field analyzer, the prevalence of significant () points in 16 points within central 10 degrees and 4 points within central 5 degrees is measured. (Left) The central visual field defect is defined because of at least 1 significant point lying in 16 points (squeal line) within central 10 degrees. (Right) The central visual field defect is not defined because of no significant point lying in 4 points (squeal dot line) within central 5 degrees.
