Surgical Outcomes of Vitrectomy for Macular Hole-induced Retinal Detachment According To Various Surgical Methods: A Multicenter Retrospective Study

Purpose To investigate the surgical outcomes of vitrectomy for macular hole-induced retinal detachment(MHRD), with respect to the surgical adjunctive method used.Method We performed retrospective multicenter study of patients who underwent vitrectomy for MHRD. The visual/anatomical outcomes after vitrectomy were analyzed. We also analyzed these outcomes according to surgical method and the presence of persistent macular hole after the vitrectomy.Result Thirty-four patients (34 eyes) from 6 hospitals were included in this study. The mean age of the patients was 64.56 ± 12.23 years; 31 patients (91.2%) were female. The mean LogMAR best-corrected visual acuity (BCVA) significantly improved 6 months after vitrectomy (p < .001). Retinal detachment completely improved in 32 eyes (94.1%). The visual prognoses and macular hole closure rates were not different depending on subretinal fluid drainage site. The presence or absence of a persistent macular hole after vitrectomy did not affect the visual outcomes. However, the recurrence of MHRD was significantly higher in eyes with persistent macular holes(p = .015).Conclusion The surgeries to treat MHRD differed in terms of the procedure depending on the surgeons, but the visual outcomes did not differ depending on the surgical adjunctive method employed. There were no differences in the visual prognoses, regardless of whether there was a persistent macular hole; however, recurrence was significantly higher in eyes with persistent macular holes. Therefore, further surgical treatment might be considered for eyes with persistent macular holes after MHRD surgery.
