We conducted a meta-analysis of published retrospective studies and compared the effectiveness of pars plana vitrectomy with and without internal limiting membrane (ILM) peeling for idiopathic epiretinal membrane (IERM). The results revealed that patients in the IERM+ILM peeling group had better BCVA after surgery within 12 months than those in IERM peeling group. But patients in the IERM peeling group showed better BCVA in the 18th month. More retrospective studies or randomized controlled trials are required to investigate and compare the long-term effect of IERM removal with and without ILM peeling.

Aim: To evaluate long term macular changes following pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling for diabetic macular edema (DME) Methods: Forty eligible eyes of 37 patients were included in this retrospective study. Best corrected visual acuity (BCVA), central macular thickness (CMT) and 5-mm macular volume (5-MV) were examined preoperatively and at postoperative 1st, 2nd, 3rd, 6th, 12th, 24th months and final visits. Response to surgical treatment was considered as recurrence, reincrease and recovery of DME based on macular changes. Results: Mean follow-up time was 51.1±19.0 months following surgery. Recurrence (n=5) and reincrease (n=17) of DME was observed in 22 eyes (55%) and additional treatments were applied. Recovery of DME was observed in 18 eyes (45%). Preoperative and final visit mean BCVAs (logMAR) were 1.08±0.37 and 0.93±0.45, respectively (p=0.02). Preoperative and final visit mean CMTs were 514.74±155.65 µm and 281.87±112.58 µm, respectively (p<0.001). The 5-MV significantly decreased following surgery (8.18±1.57 mm3 to 6.52±1.39 mm3) (p<0.001). DME was present in 12 eyes (%30) at final visit. Conclusion: Although PPV with ILM peeling had an efficacy in DME management, this effect tends to decrease over time such that considerable amount of patients required additional treatment.

Purpose. To evaluate the outcome of 23 G PPV and ILM peeling with 14% C3F8 compared with silicone oil tamponade in cases of TMHs without spontaneous closure. Methods. A retrospective comparative study included 33 eyes with TMHs; 7 eyes healed spontaneously, and the remaining 26 eyes have been treated with PPV and ILM peeling. Silicone oil was used as a tamponade for children or adults who refused to adopt face-down position (10 cases). In all other cases (16 cases), 14% C3F8 was used. These cases were followed up for 6 months postoperatively. Results. 26 cases (22 males and 4 females) were reviewed, including 10 cases treated with silicone oil and 16 cases treated with 14% C3F8. Patients’ age ranged from 9 to 54 years. The success rate was 90% in the silicone-filled (9/10) and 94% in the gas-filled (15/16) eyes. At 6 months, the mean BCVA was 0.3 ± 0.25 in the silicone group and 0.2 ± 0.13 in the gas group (p<0.05). Conclusions. Cases of TMHs should be observed for spontaneous closure. PPV with ILM peeling should be conducted for nonclosing cases. Gas and silicone oil tamponades are equally successful in anatomical and visual outcomes. This trial is registered with CTRI/2017/06/008765.

Backgrounds and Objective: Pars Plana Vitrectomy (PPV) and epiretinal membrane (ERM) peeling is the standard surgical procedure of ERM surgery. However, the effect of adding Internal Limiting Membrane (ILM) peeling to the standard surgery on macular function and structure remains still controversial. This study was aimed at investigating the effect of ILM peeling on the macular function and structure in idiopathic ERM surgery. Method: Thirty-six eyes of 34 patients were evaluated in this prospective study. The patients were divided into two groups (ILM peeling and non-ILM peeling group). While the removal of ERM was undergone alone in 19 eyes, it was combined with ILM peeling in 17 eyes. Metamorphopsia scores Vertical Metamorphopsia (VM) and Horizontal Metamorphopsia (HM), were measured at preoperative and 4 months postoperatively. Results: There was a statistically significant decrease in metamorphopsia (VM and HM) scores in both groups after the surgery. However, no statistically significant difference was found between the two groups in terms of reduction in VM scores and HM scores after surgery. Conclusion: Our study indicated that ILM peeling combined with ERM did not affect metamorphopsia scores.

A 59 years male presented with painless diminution of vision in right eye for 4 months. His vision was 20/100 in right eye and 20/30 in left eye. Fundus examination revealed epiretinal membrane  in right eye with central macular thickness of 747 μm for which he underwent 25 guage pars plana vitrectomy. Intraoperatively after internal limiting membrane peeling, during removal of the pieces of the membrane from the forceps with the endoilluminator pipe, accidentally one blade from the tip of ILM peeling forceps broke. In this report, we describe first case of inadvertent intraoperative fracture of 25- gauge Grieshaber DSP End-Grasping ILM forceps in a case of ERM who underwent vitrectomy and removal of ERM with successful removal of fractured tip of ILM forceps.

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.

Background: Previous studies have shown that epiretinal membranes (ERMs) may be associated with abnormal outer retinal anatomy. However, long-term morphological and functional results of pars plana vitrectomy (PPV) with ERM and internal limiting membrane (ILM) peeling in eyes with central bouquet (CB) alterations have not yet been investigated. Methods: In a retrospective, consecutive study all patients underwent best corrected visual acuity (BCVA) testing and spectral domain optical coherence tomography (SD-OCT) before and after a mean of 20 months (range 3–70 months) postoperatively. CB abnormalities and ERMs were classified according to Govetto’s staging systems. Results: Of the 67 eyes, 22 (34%) showed CB abnormalities at baseline. The mean BCVA increased from 0.42 at baseline to 0.20 LogMAR at final follow-up (p < 0.001). Neither ERM stage (p = 0.06) nor CB stage (p = 0.939) at baseline were significant predictors of vision improvement following surgery. Conclusions: Our results show that baseline BCVA, but not classification of CB changes and ERM at baseline, seems to be a useful predictor for functional outcomes following PPV with ERM and ILM peeling in the long-term.
