Background/aim: To examine the degree of the residual internal limiting membrane (ILM) after epiretinal mem-brane (ERM) peeling. Methods: Sixty-one eyes of 59 patients with ERM were enrolled. After ERM peeling, residual ILM was visualised with Brilliant Blue G (BBG). The residual ILM pattern was divided into three groups: (1) residual type (ILM mostly remained), (2) half type (approximately half of ILM remaind), (3) no residual type (ILM mostly removed with ERM). If ILM remained, residual ILM was removed in all cases and histologically examined using the flat mount method in 10 cases. The correlation between the degree of ERM evaluated by preoperative best-corrected visual acuity (BCVA) and residual ILM pattern was als
