Purpose: To investigate prognostic factors related to the surgical outcome of vitrectomy in myopic traction maculopathy(MTM). Methods: Medical records of patients with MTM who underwent pars plana vitrectomy with internal limitingmembrane peeling and follow-up over 12 months were reviewed retrospectively. Best-corrected visual acuity(BCVA), fundoscopic examination and spectral-domain optical coherence tomography findings were evaluatedpostoperatively. Functional success was defined as visual acuity gain and anatomical success was defined asreduction or resolution of foveoschisis without complications. Results: This study included 40 eyes of 36 patients. BCVA improved from 0.70 ± 0.44 to 0.63 ± 0.57 logarithmof minimum angle of resolution and central macular thickness decreased from 526.6 ± 132.1 to 277.8 ± 92.1μm at final follow-up. Functional success was achieved in 24 (60.0%) eyes, and 33 (82.5%) eyes reachedanatomical success. Presence of foveal detachment (FD) and higher category of myopic maculopathy wereassociated with both functional (p = 0.014, 0.021, respectively) and anatomical (p = 0.011, 0.022, respectively)failure. Longer preoperative axial length showed an association with functional failure but not with anatomicalfailure (p = 0.041). In multivariate analysis, FD was the only prognostic factor for both functional and anatomicaloutcome (p = 0.041, 0.043, respectively). Preoperative BCVA (r2 = 0.259, p = 0.001), axial length (r2 = 0.172,p = 0.008), and myopic maculopathy category (r2 = 0.336, p < 0.001) showed significant correlation with finalBCVA. Conclusions: More severe myopic maculopathy and the presence of FD are associated with poorer functionaland anatomical outcomes of pars plana vitrectomy in MTM. Better preoperative BCVA, shorter axial length,and less severe myopic maculopathy are correlated with better final BCVA.
