Agreement assessment of Wide scan circumpapillary retinal nerve fiber layer (cpRNFL) thickness between the Triton and Maestro in glaucoma eyes. (a) Bland–Altman plots showing mean differences of Wide scan cpRNFL thickness between the Triton and Maestro in glaucoma eyes were less than 3 µm. (b) Deming regression plot of thickness measurements of cpRNFL from the Wide scan between Triton and Maestro in glaucoma eyes. The plots illustrate the fitted linear models (red line) and the identity lines (Triton measurement = Maestro measurement, slope = 1) (black line). Intercepts and slopes of the fitted linear models, which are shown as mean (95% confidence interval), indicate measurements of the two devices were in excellent agreement.
