    Abstract:
    PURPOSE: To evaluate the efficacy of repeat pars plana vitrectomy and gas tamponade for persistent macular holes (MHs), especially looking at a predictive value of optical coherence tomography parameters in revisional surgery. METHODS: Retrospective, nonrandomized interventional case series of consecutive patients with a persistent MH that underwent revisional pars plana vitrectomy and gas tamponade. The primary outcome measure was anatomical closure of the MH after revisional surgery. The secondary outcome measure was a functional outcome of the MH closure based on the best-corrected visual acuity. The changes of minimum linear diameter and MH index after the primary surgery were evaluated to see if they were prognostic markers of success for the revisional surgery. RESULTS: A total of 27 patients with a persistent MH after primary MH surgery were identified, all of whom underwent a second operation with pars plana vitrectomy and gas tamponade with an internal limiting membrane peel extension in 20 cases. The MH closure rate after revisional surgery was 89% (24/27). Twenty-two cases were included in the optical coherence tomography analysis, of which 14 MHs that showed both a reduction of the minimum linear diameter and an increase in the MH index after the primary repair closed after revisional surgery. The mean best-corrected visual acuity before revisional surgery was 0.86 logMAR (20/145 Snellen) but increased significantly postoperatively to 0.69 (±0.15) logMAR (20/98 Snellen) at 3 months and to 0.49 logMAR (20/62 Snellen) at 12 months. CONCLUSION: For a persistent idiopathic MH, simple repeat pars plana vitrectomy with gas tamponade has a good anatomical and functional success rate in selected cases. The minimum linear diameter and MH index can be useful optical coherence tomography markers for prognostic guidance.
