    Comparison of scanning laser ophthalmoscopy and high-definition optical coherence tomography measurements of optic disc parameters

    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 ...
