Quadrantal thicknesses of the intraretinal layers in patients with MS compared with controls. (A) After removal of the central 1-mm zone of the fovea, quadrantal division was performed using 45° and 135° medians according to the ETDRS definition. Significant thickness reductions were found in the TRT, mRNFL, and GCIPL in MSON compared with those of MSFE and HC in quadrantal partitions using GEE models (P < 0.05). (B–H) GCIPL thickness in each quadrant of TRT and six intraretinal layers. S, superior quadrant; T, temporal quadrant; N, nasal quadrant; I, inferior quadrant. Bars = SEs.
