Vitrectomy with Inverted Fovea-Sparing Internal Limiting Membrane for Myopic Foveoschisis

Purpose. To evaluate the efficacy and safety of vitrectomy with inverted fovea-sparing internal limiting membrane, as a modified surgical technique in the treatment of the eyes with myopic foveoschisis. Methods. This study was based on a consecutive, interventional case series. A standard 25-gauge (25-G), 3-port pars plana vitrectomy combined with inverted fovea-sparing internal limiting membrane was performed on 13 eyes. Preoperative and postoperative best-corrected visual acuity, optical coherence tomography image, and central foveal thickness were analyzed. Patients were followed up for at least 6 months. Results. All 13 eyes showed dramatical resolution of myopic foveoschisis during the follow-up. The mean logarithm of minimum angle of resolution best-corrected visual acuity showed remarkable improvement from 1.06 & PLUSMN; 0.42 to 0.45 & PLUSMN; 0.25 (p < 0.0001; paired t-test). The mean central foveal thickness significantly decreased from 479.62 & PLUSMN; 113.16 mu m to 372.38 & PLUSMN; 88.12 mu m, 316.18 & PLUSMN; 73.97 mu m, and 272.40 & PLUSMN; 61.32 mu m postoperatively at 1 month, 3 months, and 6 months, respectively (p < 0.0001; paired t-test; preoperation vs. latest follow-up). Conclusions. Vitrectomy with inverted fovea-sparing internal limiting membrane can resolve myopic foveoschisis with high efficacy and safety.
