Determination of Ischemia Onset Based on Automatically Generated Spectralis SD-OCT Values in Acute Central Retinal Artery Occlusion

Figure 2

Time-dependent increase of the relative retinal thickness over 10 hours. The figure displays the RRTI in all ETDRS sectors: (a) inferior, (b) superior, (c) nasal, and (d) temporal (n = 15). In every figure, the x-axis represents time to OCT (TTO) and the y-axis the RRTI in percent in the respective sectors. Every dot represents an analyzed patient. The straight line is the ordinary least squares (OLS) regression over the first 10 hours after ischemia onset. The grey region around the regression line describes the 95% confidence interval for the expected value of y given x. It reflects the confidence in estimated parameters.
