Area classification and analysis according to the surgical method using compass microperimetry The macular area was divided into four areas. Area 1 was around the superior arcade, where neither internal limiting membrane (ILM) peeling nor indocyanine green (ICG) staining was performed. Area 2 was inferior to Area 1 and above the fovea, where ILM peeling but not ICG staining was performed. Area 3 was below the fovea, where both ILM peeling and ICG staining were performed. Area 4 was around the inferior arcade below Area 3, where ICG staining but not ILM peeling was performed. The mean retinal sensitivity of four points within each area was manually calculated
