Abstract:
·AIM:To explore the effectiveness of a new non-inverted pedicle internal limiting membrane ( ILM ) flap transposition technique in the treatment of large macular holes (MH). ·METHODS: This was a prospective pilot study which included 9 patients with 10 eyes in Jiangsu Province People's Hospital from December 2016 to February 2017. All patients was diagnosed with large MH (size >400μ m) by the spectra- domain optical coherence tomography (SD-OCT) and underwent the non-inverted pedicle ILM flap transposition surgery. Best-corrected visual acuity (BCVA), SD-OCT images, and MP-1 microperimetry tests were performed pre-operation, 1d, 1wk, 1, 3, and 6mo post-operation. ·RESULTS:The macular hole closure rate after 6mo was 100%. The averaged BCVA improved from 1. 19 ± 0. 54 (LogMAR) pre-operation to 0.70 ± 0.50 (LogMAR) post-operation (P=0.005). The mean retinal sensitivity within 8° and 2° improved from 3.14±4.52dB to 8.91±5.53dB(P=0.008), and 1.46 ± 2.94dB to 6.33 ± 4.90dB (P=0.008) respectively. Preoperative unstable fixation in seven eyes resolved at the last postoperative follow-up.·CONCLUSION: Our non-inverted pedicle internal ILM flap transposition technique shows effectiveness in the treatment of large macular holes with high MH closure rate and improving visual function.
