Fig. 2 — a: Receiver operating curves (ROC) of different anterior segment optical coherence tomography (AS-OCT) parameters. b: Receiver operating curves (ROC) of different Pentacam parameters. c: Bland–Altman plots showing the agreement between the trabecular-iris angle (ITA) measurements by Pentacam and by AS-OCT in the temporal quadrant (regression equation: y = −16.2835 + 0.4229 x; coefficient of determination R²: 0.174; p = 0.0007). D: Bland–Altman plots showing the agreement between the trabecular-iris angle (ITA) measurements by Pentacam and by AS-OCT in the nasal quadrant (regression equation: y = −11.3866 + 0.2259 x; coefficient of determination R²: 0.062; p = 0.05). AS-OCT parameters: perpendicular angle opening distance from Schwalbe line (SL) to iris (AOD-SL-Perp temporal and nasal), vertical angle opening distance from Schwalbe line (SL) to iris (AOD-SL-Vert temporal and nasal), and iridotrabecular angle (ITA temporal and nasal). Pentacam anterior segment parameters: anterior chamber depth (ACD), anterior chamber volume (ACV), and anterior chamber angle (ACA)
