Diagnostic performance of combinations of SS-OCT single scans for two-quadrant gonioscopic angle closure
| Combinations of SS-OCT scans | AUC | 95% CI |
| Horizontal (0–180)–vertical (90-270) | 0.8031* | 0.7738 to 0.8325 |
| Diagonal 45 (45–225)–diagonal 135 (135–315) | 0.8001* | 0.7696 to 0.8305 |
| Horizontal–vertical–diagonal 45–diagonal 135 | 0.7922* | 0.7634 to 0.8211 |
*P<0.001, χ2 compared with scan 80°–260° (AUC 0.82).
AUC, area under the receiver operating characteristic curve; SS-OCT, swept-source optical coherence tomography.
