a Tabandeh et al. performed a distal superior ILM flap from the MH and transposed it over the MH. b Formation of pedicle ILM by Hu et al. PFCL was injected to protect the MH and the exposed RPE before staining the ILM with ICG or BBG. Then the ILM peeling was performed circumferentially around the MH for at least 2 DD and left attached to the superior temporal retina. The pedicle ILM then rotated and transposed over the MH, with its nasal part fully covered the MH while stabilised and flattened under a larger bubble of PFCL followed by air-fluid-PFCL exchange. The authors chose either SO or autologous whole blood with C3F8 gas to prevent displacement of the ILM pedicle transposition and patients were advised to prone-posturing for 3 days
