A representative case of normal-tension glaucoma with superior visual field defect. (A) Retinal nerve fibre layer thickness (RNFLT) measurements. (B) Visual field examination. (C) RNFLT map. (D) Ganglion cell complex thickness (GCCT) map. (E) Superior retinal blood flow (RBF) measurement. The upper left image shows the fundus photograph, the white line square shows the next photograph and the green line shows the measurement location. The upper right image shows the phase image. The lower left image shows the velocity waveform of the average velocity in the blood vessel, the black line shows the artery and the grey line shows the vein. The lower right image shows the velocity profile at the maximum velocity in the artery. (F) Inferior RBF measurement. Reduced RNFLT, GCCT, lower temporal artery RBF, and temporal vein RBF were observed in the inferior hemisphere compared with the superior hemisphere, which corresponded to the glaucomatous visual field defects shown in the superior hemifield in the total and pattern deviation plots. In the Topcon RNFLT deviation map, areas with RNFLT thinner than the fifth percentile and the first percentile of the normative database were marked in yellow and in red, respectively. dB, decibel; GHT, glaucoma hemifield test; I, inferior; MD, mean deviation; N, nasal; PSD, pattern SD; S, superior; T, temporal.
