Gradual resolution of foveal herniation after epiretinal membrane peeling

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.
