Abstract

Purpose: To compare the outcomes of vitrectomy with fovea-sparing internal limiting membrane peeling (FSIP) and complete internal limiting membrane peeling (ILMP) for myopic traction maculopathy (MTM). Study design: A retrospective, observational study. Patients and methods: In this study, we included 22 eyes of 21 consecutive patients who underwent vitrectomy with FSIP or ILMP for MTM and were monitored for at least 6 months. Eleven eyes were treated with FSIP, and 11, with ILMP. Results: With FSIP, the postoperative best-corrected visual acuity (BCVA) significantly improved from 0.61 (20/82) to 0.34 (20/44; P =.009) logarithm of the minimum angle of resolution (logMAR) units. With ILMP, the postoperative BCVA improved from 0.65 (20/89) to 0.52 (20/66) logMAR units, but was not significant (P =.106). The postoperative final central foveal thickness (CFT) reduced significantly after FSIP (from 557.6 to 128.8 µm, P =.003) and ILMP (from 547.3 to 130.3 µm, P =.008). The postoperative incidence of a macular hole was 0% (0/11 eyes) with FSIP and 27.3% (3/11 eyes) with ILMP. All patients with a macular hole had foveal detachment in association with a thin fovea preoperatively. With ILMP, postoperative BCVA with a macular hole worsened by −3.5 letters; in contrast, postoperative BCVA without a macular hole improved by +10.5 letters. With FSIP, postoperative BCVA without a macular hole significantly improved by +13.5 letters (P =.009). Conclusions: FSIP resulted in significant improvement in MTM and prevented postoperative macular hole development.
