Abstract: Objective: To investigate the agreement between scanning laser ophthalmoscopy (Heidelberg retinal tomograph 3; HRT-3) and high-definition optical coherence tomography (HD-OCT) for measurements of optic nerve head (ONH) parameters. Methods: As part of a population-based cross-sectional study, 913 consecutive Chinese subjects aged 40 years and older underwent HRT-3 and HD-OCT imaging of the ONH after pupillary dilation. Limits of agreement (LOA) derived from Bland - Altman analysis were calculated for ONH measurements. Results: The mean age (±SD) of study participants was 54.2±7.2 years and 52.0% were men. The two instruments showed no difference in mean optic disc area measurements (1.98±0.37 for HD-OCT vs 1.98±0.39 mm for HRT-3, p=0.95). HD-OCT showed smaller rim area (1.29±0.24 vs 1.46±0.27 mm, p
