Table 4 Capacity of different pupil variables (alone and combined) to discriminate Adie/Ross (A/R) from neuropathy (Neuro) patients.
| Variable | Threshold* | A/R | Neuro | χ2 | P | Sens (%) | Spec (%) |
|---|---|---|---|---|---|---|---|
| DL (O–E) | >+1.4 mm | 20/34 | 23/56 | 2.672 | 0.102 | 58.8 | 58.9 |
| AL | >1 mm | 18/34 | 7/56 | 17.247 | <0.001 | 52.9 | 87.5 |
| LR | <12.2% | 40/58 | 38/75 | 4.516 | 0.034 | 69.0 | 49.3 |
| NR | <24.4% | 30/53 | 41/66 | 0.372 | 0.542 | 56.6 | 37.9 |
| LND | <11.9% | 29/53 | 22/65 | 5.182 | 0.023 | 54.7 | 66.2 |
| SP | Present | 32/35 | 27/39 | 5.624 | 0.018 | 91.4 | 30.8 |
| AL+SP | As above | 14/24 | 3/29 | 11.765 | <0.001 | 58.3 | 89.7 |
| AL+SP+LND | 6/20 | 2/26 | 2.517 | 0.113 | 30.0 | 92.3 |
*Arbitrary thresholds giving maximum discrimination between patient groups.
DL (O–E), deviation from expected diameter in the light; AL, anisocoria in the light; LR, light response; NR, near response; LND, light‐near dissociation; SP, sector palsy. Sens, sensitivity; spec, specificity.
