Effect Of Optic Disk—Fovea Distance On Measurements Of Individual Macular Intraretinal Layers In Normal Subjects
Purpose: To investigate the effect of optic disk—fovea distance (DFD) on measurements of macular intraretinal layers using spectral domain optical coherence tomography in normal subjects. Methods: One hundred and eighty-two eyes from 182 normal subjects were imaged using spectral domain optical coherence tomography. The average thicknesses of eight macular intraretinal layers were measured using an automatic segmentation algorithm. Partial correlation test and multiple regression analysis were used to determine the effect of DFD on thicknesses of intraretinal layers. Results: Disk—fovea distance correlated negatively with the overall average thickness in all the intraretinal layers (r ≤ −0.17, all P ...
