We demonstrate the gradual resolution of foveal herniation with optical coherence tomography (OCT) images after epiretinal membrane (ERM) removal. A young male presented with diminished vision in the left eye (OS). Examination of OS revealed an ERM and thickening of the foveal region. OCT delineated the ERM clearly. It also showed a central defect in the ERM through which the inner retinal layers had prolapsed into the vitreous cavity leading to foveal herniation. The patient underwent vitrectomy and surgical removal of the ERM. After removing the source of macular traction, over a period of 4 months, gradual reduction in height of the elevated central foveal tissue was observed. At 6 months, the foveal bulge had reduced remarkably and remained stable. The resolution of foveal herniation after ERM removal is a slow process. The OCT images convey that it may take few months for the foveal bulge to decrease in height. When the outer retinal layers are normal, visual recovery, though delayed, is appreciable.
我们通过光学相干断层扫描（OCT）图像展示了视网膜前膜（ERM）切除术后黄斑裂孔疝的逐渐消退。一名年轻男性左眼（OS）视力下降。对OS的检查发现有ERM和黄斑区增厚。OCT清晰地勾勒出了ERM。它还显示ERM中有一个中央缺损，通过该缺损，视网膜内层脱垂到玻璃体腔，导致黄斑裂孔疝。患者接受了玻璃体切除术并手术切除了ERM。去除黄斑牵引源后，在4个月的时间里，观察到中央黄斑组织隆起高度逐渐降低。6个月时，黄斑隆起明显减小并保持稳定。ERM切除术后黄斑裂孔疝的消退是一个缓慢的过程。OCT图像显示，黄斑隆起高度可能需要几个月才能降低。当视网膜外层正常时，视力恢复虽然延迟，但很明显。
