Background: Vitrectomy 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. Objectives: This 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. Methods: The 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. Results: Five 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 to 7.66; P = 0.01). The postoperative VA was significantly better in the inverted ILM flap group than 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 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 two groups at the 6-month follow-up (WMD, -0.09; 95% CI, -0.20 to 0.02; P = 0.10). Conclusions: Vitrectomy with 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.

Introduction and purpose. Idiopathic macular hole (IMH) is an urgent medical and social problem of the population of developed countries. It is known that microinvasive 3-port vitrectomy with gas-air tamponade is a generally accepted method of surgical treatment of IMH. There is still no clear understanding of the reasons for incomplete functional success in this category of patients, despite the anatomical success.Thus, there is a need to develop and implement in clinical practice a modification of the ILM peeling technique for the treatment of small and medium-diameter of IMH, which would not be inferior in anatomical effectiveness to existing methods and would be accompanied by a less damaging effect on the structures of the retina. Material and methods. The study included 10 patients with a diagnosis of IMH, who underwent a 3-port microinvasive 25G vitrectomy with the preservation of foveal ILM. Results. The analysis of the clinical and functional results of surgical treatment of IMH with the foveal fragment left revealed the complete closure of the macular tear, the absence of gross defects of the ellipsoid zone, an increase in the values of the average visual acuity and microperimetry from the 1st month of dynamic observation. Conclusion. The proposed low-traumatic method of fovea - sparing ILM peeling provides stable anatomical and functional result, the restoration of both morphological and functional parameters, and minimizes the mechanical impact on the retina in the fovea. Key words: macular rupture, internal limiting membrane, fovea-sparing ILM peeling.

Aim: To investigate the outcome of the inverted Internal Limiting Membrane (ILM) flap technique for extra large idiopathic macular holes (MHs).Methods: A retrospective non-comparative surgical case series of seven eyes of 7 patients with MHs (base diameter of at least 1000 ?m) was conducted. All the MHs were treated using pars plana vitrectomy and brilliant blue G (BBG)-assisted inverted ILM flap technique. Spectral Domain- Optical Coherence Tomography (SD-OCT) images were used to assess the anatomical outcomes of surgery including the macular microstructure, while Best Corrected Snellen Visual Acuity (BCSVA) was used to evaluate the functional outcomes.Results: The average MH size was 1241microns and average symptom duration was nineteen months. All eyes achieved successful anatomical closure and there was no occurrence of a flat open type closure. SD-OCT microstructural study revealed a reconstruction of the Ellispod Zone (EZ) and External Limiting Membrane (ELM), in only 3 eyes. There was an improvement in visual acuity in 5 eyes, while 2 eyes maintained the same as pre operative vision. The largest increase in post operative visual acuity gain was a 4-line improvement in Best Corrected Snellen Visual Acuity (BCSVA) noted in one of the 3 eyes with reconstructed EZ and ELM. The 3 months symptom duration in this patient was the shortest in this series.Conclusion: Inverted ILM flap technique is a safe and effective approach for the management of extra large chronic idiopathic MHs with demonstrably good anatomical and limited functional results in a majority of cases. Postoperative reconstruction of the microstructure is however seen only in a minority of eyes. Despite an absence of the outer retina (EZ and ELM), some eyes still experience an improvement in vision. The symptom duration may play a vital role in functional outcome in this subset of extra large chronic MHs.
