Objective To observe the long-term efficacy and safety of macular buckling (MB) in the treatment of high myopia traction maculopathy. MethodsA retrospective clinical study. From January 2014 to December 2017, 57 eyes of 57 patients with high myopia traction maculopathy who underwent MB treatment at Zhongshan Ophthalmic Center of Sun Yat-sen University were included in the study. Among them, there were 15 males with 15 eyes, average age was 51.80±10.72 years; there were 42 females with 42 eyes, average age was 59.14±11.51 years. There were 21 eyes of 21 cases with highly myopic macular hole with macular detachment (MHMD), and 36 eyes in 36 cases with highly myopic foveoschisis with macular detachment (FSMD), and they were grouped accordingly. All patients underwent best corrected visual acuity (BCVA), optical coherence tomography (OCT), and axial length (AL) measurements. The standard logarithmic visual acuity chart was used for BCVA examination, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. All patients underwent MB, either on its own or combined with vitrectomy. Patients with significant vitreous macular traction on OCT were treated with combined surgery. One, 3, 6 months and 1, 2, 3, and 4 years after the operation, the same equipment and methods before the operation were used to conduct related examinations, and the long-term efficacy and safety of the two groups of eyes were observed. ResultsBefore surgery, the logMAR BCVA of eyes in MHMD group and FSMD group were 1.35±0.47 and 1.17±0.59, respectively; 4 years after surgery, they were 1.02±0.49 and 0.73±0.55, respectively. The BCVA improved significantly at postoperative 4 years than preoperative in both groups (P=0.039, 0.001). In the eyes with MHMD, the BCVA was found to be significant improved 3 years after surgery (P=0.042). Whereas, in the eyes with FSMD, the BCVA was found to be significantly improved 3 months after surgery (P=0.013). Macular reattachment was achieved in 100% of cases, while macular hole closure rate was achieved in 66.7% in the MHMD group. In the FSMD group, either macular reattachment rate or the foveoschisis resolution rate was 97.2%. After surgery, choroidal neovascularization was observed in 2 eyes, and 3 eyes with intraretinal cyst. ConclusionMB may represent a safe and effective surgical option for the treatment of high myopia maculopathy.
