  Purpose: To investigate the agreement between two spectral domain optical coherence tomography (SD-OCT) instruments in Schwalbe’s line (SL) based anterior chamber angle parameters and to evaluate their repeatability and reproducibility. Methods: The inferior irido-corneal angle of 114 eyes from 59 participants (29 glaucoma and 30 normal) were scanned twice with the Optovue SD-OCT and Cirrus SD-OCT under controlled low luminance conditions. SL angle opening distance (SL-AOD) and SL trabecular-iris-space area (SL-TISA) were graded by masked certified graders at the Doheny Image Reading Center. Results: The mean SL-AOD/SL-TISA was 623±271μm/ 0.221 ± 0.106 mm2 for the Cirrus and 611 ± 267 μm/ 0.215 ± 0.112 mm2 for the RTVue. Excellent repeatability (intraclass correlation coefficient ICC&g..
