Table 1 Change in BCVA through the study

From: Inverted ILM flap, free ILM flap and conventional ILM peeling for large macular holes

Surgical technique Baseline (logMAR) 1 month (logMAR) 3 months (logMAR) Alpha (3 months)
Group A
 (Conventional 360° ILM peeling) 0.925 ± 0.5 0.656 ± 0.06 0.707 ± 0.3 0.3
Group B
 (Inverted-flap technique) 0.953 ± 0.2 0.794 ± 0.3 0.616 ± 0.2 0.007*
Group C
 (Free-flap technique) 1.097 ± 0.4 0.951 ± 0.4 0.704 ± 0.3 0.06
Alpha among groups 0.6 0.6 0.1
  1. All three groups displayed a trend toward visual improvement, but only patients in group B reached statistical significance at the 3 months of follow-up
  2. BCVA best corrected visual acuity, ILM internal limiting membrane
  3. *Statistically significant
