Table 1.

Averaged thickness measurements ($\text{mean}\pm \mathrm{SD}$) per scanning session, mean thickness values ($\mathrm{mean}\pm \mathrm{SD}$) calculated from the two scanning session’s data, coefficients of repeatability, and intraclass correlation coefficients obtained for retinal segments (including their corresponding foveal center measurements) and nine intraretinal layers shown in Fig. 1. Results were obtained after scanning twice (Sessions 1 and 2) 23 eyes of the 12 subjects under the same conditions by one examiner.
