Long-Term Outcomes Of Vitrectomy And Internal Limitıng Membrane Peeling For Myopic Foveschisis

Abstract

INTRODUCTION: To evaluate the long-term results of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) peeling in patients with myopic foveoschisis (MF) METHODS: In this retrospective study, the medical records of the patients who underwent PPV combined with ILM peeling due to myopic foveoschisis were examined. The best corrected visual acuity (BCVA) and the change in BCVA were evaluated. Preoperatively fovea detachment (FD), presence of postoperative ellipsoid zone defect (EZD), and preoperative and postoperative central macular thickness (SMC) were evaluated using optical coherence tomography (OCT). RESULTS: Twenty-five eyes of 20 patients were included in the study. The mean preoperative BCVA was 1.41 +- 0.32 logMAR (1.0-1.8 logMAR) and postoperative BCVA was 0.87 +- 0.41 logMAR (0.3-1.8 logMAR). Postoperative visual acuity improved in 20 eyes (80%). Postoperatively, 4 eyes (16%) had no change in visual acuity and 1 eye (4%) had a decrease in visual acuity. The mean CMT was 683.8 µm +- 155.4 and 262.6 µm +- 46.5 preoperatively and postoperatively, respectively. There was a significant decrease in CMT in the first year after surgery when it was compared with the preoperative CMT (p <0.001). In 20 (80%) eyes, foveoschisis was completely resolved anatomically in the first year after surgery. In 5 eyes (20%), there was a decrease in CMT in the OCT, and a partial improvement in the foveoschisis. DISCUSSION AND CONCLUSION: It is concluded that vitrectomy combined with ILM peeling in the treatment of myopic foveoschisis is an effective and reliable surgical method for increasing visual acuity and providing anatomical improvement.
