The correlation between optical coherence tomography retinal shape irregularity and axial length.

ABSTRACT: PURPOSE:To describe the retinal contour in optical coherence tomography (OCT) images, and report the relationship between retinal contour and axial length. METHODS:Retinal contour was defined by the path of the retinal pigment epithelial (RPE) line in macular and extra-macular OCTs of 70 eyes of 70 participants recruited from ophthalmology clinics in South Australia. The shape of this contour was described by the best-fit curvature (K), and Fourier analysis of the difference between K and the RPE. The Fourier transformation was summarised by total difference (sumdiff), maximum single frequency difference (MaxE), and root mean square difference (rmse) between each B scan residual and the average normal. All-of-eye and regional median and interquartile range (IQR) shape features were correla
