Abstract
PURPOSE: To introduce and evaluate a modified therapeutic strategy for idiopathic macular holes (IMH). METHODS: A retrospective review of patients with diagnosis of IMH from July 2016 to January 2020 at Peking Union Medical College Hospital. These patients were managed strictly according to our therapeutic strategy. Their comprehensive clinical data were collected and analyzed. RESULTS: 209 eyes suffering stage II to IV IMH were identified. For stage II IMH, the spontaneous closure rate was 8.9%, the initial success rate of intravitreal injections (IVI) of expansile gas and pars plana vitrectomy (PPV) + internal limiting membrane peeling (ILMP) + air tamponade was 84.2% and 100%, respectively. The initial success rate of PPV + ILMP + air tamponade for stage III and stage IV IMH was 89.8% and 86.4%, respectively. Following our intervention strategy, stage II IMH achieved a final IMH closure rate of 100%, stage III of 99% and stage IV of 97%. The final best corrected visual acuity was significantly improved (P < 0.05). Sitting position air-fluid (A-F) exchange alone successfully induced IMH closure in 7/19 eyes that did not achieve IMH closure by initial PPV. For three refractory cases that failed additional PPV + ILM stuffing, intraoperative OCT assisted PPV + sub-retinal BSS injection successfully induced the IMH closure. As the remaining three unclosed IMH cases were dry and stable, no more interventions were conducted. CONCLUSION: The general IMH closure rate based on our therapeutic strategy was satisfactory with a favorable prognosis. IVI expansile gas and sitting position A-F exchange were effective and highly cost-effective under certain circumstances.
