Correlation Between Main Outcome (Open or Closed Macular Hole) and Operative Technique (ILM Flap or ILM Peeling)
| Variable | Intervention n (%) | p | |
|---|---|---|---|
| ILM Flap | ILM Peeling | ||
| Overall | n = 48 | n = 61 | |
| Open | 1 (2.1) | 12 (19.7) | 0.006 |
| Closed | 47 (97.9) | 49 (80.3) | |
| Small MH | n = 6 | n = 22 | |
| Open | 0 (0.0) | 1 (4.5) | > 0.999 |
| Closed | 6 (100.0) | 21 (95.5) | |
| Medium MH | n = 18 | n = 19 | |
| Open | 1 (5.6) | 1 (5.3) | > 0.999 |
| Closed | 17 (94.4) | 18 (94.7) | |
| Large MH | n = 24 | n = 20 | |
| Open | 0 (0.0) | 10 (50.0) | < 0.001 |
| Closed | 24 (100.0) | 10 (50.0) | |
| High myopia | n = 7 | n = 9 | |
| Open | 0 (0.0) | 3 (33.3) | 0.213 |
| Closed | 7 (100.0) | 6 (66.7) | |
Notes: Small MH grade, ≤250 µm; Medium MH grade, >250 – < 400 µm; Large MH grade, ≥400 µm; High myopia: if it exceeded 6 dioptres or if an axial eye length was > 26 mm; n (%) was given for each variable; p < 0.05 was considered statistically significant; Analyses were made with Fisher’s exact test.
Abbreviations: n, number of subjects in a group; MH, macular hole.
