Summary | PURPOSE:To determine the degree of misalignment between the center of foveal avascular zone (FAZ) and the center of foveal photoreceptors in eyes with an idiopathic epiretinal membrane (ERM).METHODS:We reviewed the medical records of 61 eyes with an idiopathic ERM. A 3×3 mm area centered on the fovea was scanned with optical coherence tomography angiography (OCTA) before and at 6 months after surgery. The center of FAZ and the center of foveal photoreceptors were detected by en face OCTA images and sequential OCT B-sections in the macular region. The presence or absence of ectopic inner foveal layers (EIFLs) was also evaluated.RESULTS:The mean distance from the center of foveal photoreceptors to the center of FAZ was 111.7 ± 106.8 μm in eyes with preoperative ERM. This distance was significantly correlated with the preoperative central foveal thickness (r = 0.33, P = 0.0104). Preoperatively, the EIFLs were present in 27 (44.3%) of 61 eyes. The foveal misalignment was greater in eyes with EIFLs than in those without EIFLs (158.6 ± 140.0 μm vs 74.4 ± 45.4 μm, P < 0.0003). At 6 months after ERM surgery, the foveal misalignment was significantly reduced to 73.7 ± 48.0 μm (P = 0.0018).CONCLUSION:Determining the degree of misalignment between center of FAZ and center of foveal photoreceptors might be a useful way to evaluate the degree of ERM traction. |
