Mean deviation of affected and less affected hemifields in patients with altitudinal asymmetric field defects are presented (median, 10, 90% percentiles). Furthermore the mean defects of the temporal superior and inferior field of NPG with symmetric field defects are given (median, 10, 90% percentiles)
| Mean deviation affected branch (dB) | Mean deviation less affected branch (dB) | Mean deviation superior field (dB) | Mean deviation inferior field (dB) | Significance | |
| NPG with altitudinal asymmetric field defects | −9.1 (−25.3; −3.2) | −1.7 (−6.9; 0.5) | p=0.002 | ||
| NPG with symmetric field defects | −4.1 (−15.1; 0.5) | −3.4 (−15.4; 0.4) | p=0.88 |
