Comparison of Individual Retinal Layer Thicknesses after Epiretinal Membrane Surgery with or without Internal Limiting Membrane Peeling

Figure 2

Examples of epiretinal membrane surgery with and without internal limiting membrane peeling. (a) For the ILM peeling (P) group, initial removal of posterior hyaloid membrane and ERM was performed using intraocular forceps with assistance of triamcinolone injection for better visualization. The ILM was double stained with 0.2 mL of 1 mg/mL indocyanine green (ICG) solution (DID-Indocyanine Green inj, Dongindang Pharmaceutical, Siheung, Republic of Korea). The ILM, which was stained light-green, was peeled using a 25-gauge ILM forceps. An area of approximately 2 to 3 disc diameters centered on the macula of the ILM was peeled. After the initial ILM peeling, ICG dye solution was reinjected to visualize residual ILM. There was no residual ILM visible by ICG dye staining within 2 to 3 disc diameters of the macular center (black arrow). (b) For the non-ILM peeling (NP) group, after initial posterior hyaloid membrane and ERM removal, ICG dye solution was injected over the macula region to ensure that ILM remained intact (red arrow).
