Foveal hernia: morphological characteristics and result after idiopathic epiretinal membrane peeling

Foveal hernia (FH) can be detected by optic coherence tomography. FH refers to the prolapse of the innermost retinal layers into the vitreal cavity. It occurs in patients with an epiretinal membrane that does not cover the central foveal area. This present case exposes the sudden development of contractility in an idiopathic epiretinal membrane after years of stable follow-up, with no signs of progression. Additionally, this case report also shows the rapid recovery of the retinal structure after removal of the membrane. In surgical imaging with membrane staining and during its extraction, the eyelet (or slot/opening) on the foveal surface is clearly visible.
