ObjectiveTo systematically evaluate the effect of pars plana vitrectomy (PPV) combined total peeling of internal limiting membrane (ILM) versus fovea-sparing peeling of ILM for myopic foveoschisis. MethodsA evidence-based medicine study. Chinese and English as search terms for myopic foveoschisis, vitrectomy, and peeling of internal limiting membrane were used to search literature in China National Knowledge Infrastructure, Wanfang database, VIP database, PubMed of National Library of Medicine, Medline, Embase, and Cochrane Library. The high myopic macular schisis was selected as the research object, the intervention method was PPV combined with complete ILM peeling and combined with foveal preservation ILM peeling surgery clinical control study between Jan 1, 2010, and Jun 31, 2021. Incomplete or irrelevant literature and review literature were excluded. The method of Newcastle-Ottawa Scale system was used to evaluate the included literature. The literature was meta-analyzed by RevMan5.3 software. The mean difference (MD) and a confidence interval (CI) of 95% were used to describe the effect sizes of continuous data, fixed effects model was performed. The data including the best corrected visual acuity (BCVA), central fovea thickness (CFT), and postoperative macular hole (MH) were analyzed. ResultsIn those databases, 232 articles based search stratery were totally retrieved, and 10 articles (417 eyes) were finally included for meta-analysis with 245 eyes for PPV combined total peeling of ILM and 172 eyes for PPV combined fovea-sparing peeling of ILM. Meta-analysis results showed there was no significant difference in BCVA and CFT between the two groups (BCVA: MD=0.05, 95%CI 0.00-0.11; P＞0.05; CFT: MD=－4.79, 95%CI －18.69-9.11, P＞0.05). It was compared with the incidence of MH, the difference was statistically significant (odds ratio=5.70, 95%CI 2.22-14.61, P＜0.05). ConclusionBCVA and CFT could be improved by PPV combined total and fovea-sparing peeling of ILM for myopic foveoschisis; compared with complete ILM peeling, the incidence of MH was lower after foveal-sparing ILM peeling.
