|---|---|---|---|
| Preoperative size of the MH (µm) | 492±195 | 270±120 | 0.0669 |
| MH diameter ≤400 µm (n) | 3 | 6 | |
| MH diameter >400 µm (n) | 5 | 2 | |
| VM stage of the MH* | 0.2620 | ||
| Stage 1B | – | 1 | |

*Optical coherence tomography staging: stage 1B, impending macular hole, which opens the outer retinal layer; stage 2, full thickness idiopathic macular hole with vitreous attached to the edge of the hole through the pseudo operculum; stage 3, vitreous detached from the macula but attached to the optic disc; stage 4, complete posterior vitreous detachment.16
ILM, internal limiting membrane; MH, macular hole; VM, vitreomacular.
