a i-ILM Flap by Michalewska et al. Following core vitrectomy, ILM was stained with TB and ERM was removed if present. Approximately 2 DD of ILM was peeled circumferentially and left attached to the edges of the MH. The peripheral ILM was trimmed and the central remnant of ILM was massaged until inverted over the MH. Subsequently, air–fluid exchange was performed with intraocular gas tamponade. Patients were advised to stay in a position that allowed them to see the air bubble in their central vision for 3–4 days. b Left—Shin et al. stained the ILM using brilliant blue-G (BBG) and removed the surrounding ILM but a 1 DD-sized flap superiorly to MH. PFC was injected over the flap for stabilization and repositioning if needed. Right—Michalewska et al. performed temporal i-ILM flap and about 2 DD of ILM was peeled temporally to the MH edge. The flap was then inverted over the MH until adequate coverage was obtained
