Abstract
Persistence represents the major reason for failure of primary macular hole repair. A variety of surgical approaches are available for treating persistent macular holes. To compare clinical outcome of re-pars plana vitrectomy combined with autologous platelet concentrate and sulfur hexafluoride 20% gas tamponade with heavy silicone oil in persistent macular hole. Records of 48 consecutive eyes with persistent macular holes which underwent re-pars plana vitrectomy with either heavy silicone oil (35 eyes, persistent macular-hole minimum linear diameter: 518.8 ± 171.1 µm) or autologous platelet concentrate and sulfur hexafluoride 20% (13 eyes, persistent macular hole-minimum linear diameter: 454.1 ± 211.3 µm) were reviewed retrospectively. All patients underwent measurements of anatomical persistent macular hole characteristics evaluated by optical coherence tomography and visual function. Cases in which anatomical success failed after first re-pars plana vitrectomy were treated with the other surgical techniques, comparable to a cross-over design. Persistent macular hole closure rate was 57.1% with autologous platelet concentrate and sulfur hexafluoride 20% and 45.7% with heavy silicone oil (p = 0.102). Functional results were comparable when persistent macular hole closure was achieved (p ⩾ 0.741), but significantly better for the autologous platelet concentrate with sulfur hexafluoride 20% group when persistent macular hole closure failed (p = 0.019). Re-pars plana vitrectomy combined with autologous platelet concentrate and sulfur hexafluoride 20% seems to achieve at least non-inferior persistent macular hole closure rates and comparable functional results when compared to heavy silicone oil, suggesting autologous platelet concentrate and sulfur hexafluoride 20% as a safe surgical alternative in persistent macular hole. Especially when persistent macular hole closure failed, autologous platelet concentrate with sulfur hexafluoride 20% seems to be superior regarding visual outcome.
