Vitrectomy with inverted internal limiting membrane flap versus internal limiting membrane peeling for macular hole retinal detachment in high myopia: a systematic review of literature and meta-analysis.

ABSTRACT: PURPOSE:To evaluate the effect of vitrectomy with inverted internal limiting membrane (ILM) flap for the treatment of macular hole retinal detachment (MHRD) in high myopia compared with that of ILM peeling. METHODS:PubMed, EMBASE, Web of Science, MEDLINE, Ovid, Wan Fang and CNKI were systematically reviewed. The primary outcome parameters were the MH closure rate, retinal reattachment rate and postoperative BCVA. Secondary outcome parameters, included intraoperative or postoperative complications. RESULTS:Seven retrospective comparative studies including 228 eyes were selected. No significant difference was detected in either postoperative BCVA (MD -0.07; 95% CI: -0.17 to 0.03; p?=?0.16) or the improvement in postoperative BCVA (MD -0.17; 95% CI: -0.50 to 0.16; p?=?0.32) between the ILM flap group and ILM peeling group. The retinal reattachment rate using inverted ILM flap was not significantly different from that using ILM peeling (odds ratio (OR) 2.24; 95% CI: 0.75-6.73; p?=?0.15). The MH closure rate was higher with inverted ILM flap than with ILM peeling (OR 11.86; 95% CI: 5.65 to 24.92; p?

Project description:BackgroundVitrectomy with internal limiting membrane (ILM) peeling is an effective surgical procedure for the treatment of macular holes (MHs). However, there is a possibility of poor postoperative anatomical closure with conventional ILM peeling for MHs larger than 400 μm. Therefore, a novel inverted ILM flap technique was developed for such cases.ObjectivesThis meta-analysis study was performed to evaluate and compare the anatomical and visual outcomes of the inverted ILM flap technique and ILM peeling in large MHs.MethodsThe Cochrane Library, PubMed, and Embase databases were searched to identify randomized controlled trials (RCTs). The trial eligibility and risk of bias were assessed according to Cochrane review methods. The primary outcome measures included MH closure rate and postoperative visual acuity (VA). Subgroup analysis of postoperative VA based on follow-up time was also conducted. Pooled odds ratios (ORs), weighted mean difference (WMD), and 95% confidence intervals (CIs) were calculated. Statistical analysis was performed using RevMan 5.3 software.ResultsFive RCTs with a total of 155 eyes in the inverted ILM flap group and 161 eyes in the ILM peeling group were included in this meta-analysis. Statistical meta-analysis revealed that the overall MH closure rate in the inverted ILM flap group was significantly higher than that in the ILM peeling group (OR = 3.10; 95% CI: 1.25-7.66; p = 0.01). The postoperative VA was significantly better in the inverted ILM flap group than the ILM peeling group (WMD = -0.14; 95% CI: -0.21 to -0.07; p = 0.0002). The subgroup meta-analysis indicated that the postoperative VA was significantly better in the inverted ILM flap group than the ILM peeling group (WMD = -0.17; 95% CI: -0.26 to -0.08; p = 0.0004) at the 3-month follow-up. However, no significant difference was observed between the 2 groups at the 6-month follow-up (WMD = -0.09; 95% CI: -0.20 to 0.02; p = 0.10).ConclusionsVitrectomy with the inverted ILM flap technique showed a higher anatomical closure rate as well as visual gain - although only in the short term as no difference in visual recovery was found at the 6-month follow-up - than did ILM peeling in large MHs. The inverted ILM flap technique should be considered as a preferred and routine procedure for the treatment of patients with MHs larger than 400 µm.
