Abstract
BackgroundMyopic foveoschisis (MF) is among the leading causes of visual loss in high myopia. However, it remains controversial whether internal limiting membrane (ILM) peeling or gas tamponade is necessary treatment option for MF.MethodsPubMed, EMBASE, CBM, CNKI, WANFANG DATA and VIP databases were systematically reviewed. Outcome indicators were myopic foveoschisis resolution rate, visual acuity improvement and postoperative complications.ResultsNine studies that included 239 eyes were selected. The proportion of resolution of foveoschisis was higher in ILM peeling group than non-ILM peeling group (OR = 2.15, 95% CI: 1.06–4.35; P = 0.03). The proportion of postoperative complications was higher in Tamponade group than non-Tamponade group (OR = 10.81, 95% CI: 1.26–93.02; P = 0.03). However, the proportion of visual acuity improvement (OR = 1.63, 95% CI: 0.56–4.80; P = 0.37) between ILM peeling group and non-ILM peeling group and the proportion of resolution of foveoschisis (OR = 1.80, 95% CI: 0.76–4.28; P = 0.18) between Tamponade group and non-Tamponade group were similar.ConclusionsVitrectomy with internal limiting membrane peeling could contribute to better resolution of myopic foveoschisis than non-peeling, however it does not significantly influence the proportion of visual acuity improvement and postoperative complications. Vitrectomy with gas tamponade is associated with more complications than non-tamponade and does not significantly influence the proportion of visual acuity improvement and resolution of myopic foveoschisis.

Myopic foveoschisis (MF) is among the leading causes of visual loss in high myopia
6 studies, [21,22,23,24,25,26] 186 eyes (86 eyes in internal limiting membrane (ILM) peeling group, 100 eyes in non-ILM peeling group) were included in the meta-analysis of vitrectomy with ILM peeling versus that without ILM peeling for the treatment of MF
This study shows that vitrectomy with gas tamponade does not significantly improve resolution of MF and even has higher postoperative complications proportion than vitrectomy without gas tamponade
Summary
Myopic foveoschisis (MF) is among the leading causes of visual loss in high myopia It remains controversial whether internal limiting membrane (ILM) peeling or gas tamponade is necessary treatment option for MF. It has been named shallow detachment of the macula, foveal retinoschisis, macular retinoschisis or posterior retinoschisis [1]. Anomalous or incomplete posterior vitreous detachment as well as contraction of attached cortical vitreous are considered to be the major factors. For instance, excessive rigidity or poor elasticity of the internal limiting membrane (ILM), progressive
