  1. Abbreviation: n, number; IOP, intraocular pressure.
  2. *Group A: Vitrectomy was performed on the 1st–7th day upon injury.
  3. *Group B: Vitrectomy was performed on the 8th–14th day upon injury.
  4. *Group C: Vitrectomy was performed after 14 days upon injury.
  5. *X2/F: Chi-square test was applied to compare the differences among the three groups.
  6. **P < 0.05.
