Study summary

To report cases who had received previous fovea-sparing internal limiting peeling membrane and developed secondary fovea epiretinal membrane contraction

Read the detailed description

Purpose: To report the rare complication of foveal epiretinal membrane (ERM) formation on residual internal limiting membrane (ILM) with severe contraction after previous fovea-sparing internal limiting membrane (ILM) peeling.

Study design: Retrospective case series Methods: We report patients who previously received fovea-sparing ILM peeling and complicated with foveal ERM formation and contraction.
