peeling-reposition
"After dying with Brilliant Blue G (BBG, Brilliant Blue; Gender, Germany), a horizontal ILM strip is peeled off in inferior quadrant of macular area. Then the ILM was peeled from inferior to superior area continuously. The ILM roll was unfolded with assistance of perfluoro-n-octane (PFO). Finally, the position of the fixed ILM flap is adjusted under PFO bubble using flute needle or forceps.This was followed by a complete fluid-gas exchange using 14% perfluoropropane gas.Patients are introduced to maintain facedown position for two weeks postoperatively."
peeling
After dying with Brilliant Blue G (Brilliant Blue; Gender, Germany), a horizontal ILM strip is peeled off in inferior quadrant of macular area. Then, the strand of ILM was peeled off radially from the foveal center to vascular arcade. In result, a round -shaped with 2.5-3.5 disc diameter ILM -peeled area was created.This was followed by a complete fluid-gas exchange using 14% perfluoropropane gas. Patients are encourage to maintain facedown position for two weeks postoperatively.

We intravitreal injected 0.1ml of Brilliant Blue G (Brilliant Blue; Gender, Germany) to dye ILM before ILM peeling.
