Clinical effect of retinal inner limiting membrane peeling combined with flute needle drawing in the treatment of idiopathic macular hole without staining dye / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To investigate the efficacy of pars plana vitrectomy(PPV)with inner limiting membrane(ILMP)flap peeling and flute needle drawing in the treatment of idiopathic macular hole(IMH)without staining dye.<p>METHODS: A retrospective non-randomized case study on 76 patients(76 eyes)were diagnosed with IMH in our hospital from January 2018 to January 2019, 38 eyes were treated with PPV combined with ILMP and air tamponade without staining(group A), the remaining 38 eyes were treated with PPV combined with ILMP, needle drawing the Hole edge and air tamponde without staining(group B). The patients were followed up for more than 6mo, the macular hole closure, the best correct visual acuity(BCVA)and postoperative complication were analyzed in the two groups.<p>RESULTS: At 6mo after surgery, the closure rate of MH and BCVA improvement rate in group A were significantly lower than those in the group B(84% <i>vs</i> 100%, 76% <i>vs</i> 95%, <i>P</i><0.05). With the passage of postoperative time after surgery, the BCVA of two groups of patients gradually improved, and the BCVA of group B was better than that of group A at 7, 14d, and 1, 3, 6mo after surgery(<i>P</i><0.05). There were no postoperative complications in two groups.<p>CONCLUSION: PPV combined with ILM peeling without staining agent and flute needle drawing is effective in treating IMH, which is better than ILM-P group in both closure rate and BCVA improvement.
