Meta-Analysis Review
TOPIC
A variety of different tamponade agents are used with vitrectomy combined with internal limiting membrane (ILM) peeling for the treatment of idiopathic macular holes. These agents include air, gas (sulfur hexafluoride [SF], hexafluoroethane [CF], and perfluoropropane [CF]), and silicone oil. The optimal tamponade agent is uncertain, and we aimed to review the effect of tamponade choice on hole closure and visual outcomes.
CLINICAL RELEVANCE
Although most surgeons initially chose to use long-acting gas (CF), there has been a gradual change in practice to the increasing use of the medium- (CF) and short-acting gases (SF) or even air. However, there is no consensus regarding their relative efficacies.
METHODS
Systematic review and meta-analysis of randomized controlled trials (RCTs) and prospective and retrospective comparative cohort studies comparing different tamponade agents in patients undergoing vitrectomy and ILM peeling for primary idiopathic macular holes. For RCTs, the risk of bias was assessed using the Cochrane Risk of Bias tool for RCTs, whereas for nonrandomized studies, the Risk of Bias in Nonrandomized Studies of Interventions tool was used.
RESULTS
Thirteen publications, including 2 RCTs, were identified. Overall, there was no significant difference in the anatomic closure rates between studies using SF compared with either CF or CF (odds ratio [OR] = 0.74; 95% confidence interval [CI] = 0.51-1.08). A subgroup analysis showed a significantly higher closure rate using SF (OR = 0.49; 95% CI = 0.30-0.79) in patients without postoperative posturing but not in those who were advised to posture facedown. The visual outcomes and adverse events were not significantly different. The comparisons of anatomic closure rates of patients treated with gas tamponade vs. silicone oil and with air vs. SF showed no significant differences. The included studies had a number of methodological limitations and heterogeneities, making conclusions imprecise, with low or very low certainty by the Grades of Recommendation, Assessment, Development and Evaluation approach.
CONCLUSION
The current evidence base for tamponade selection with vitrectomy and ILM peeling for full-thickness macular hole has several major limitations. Further appropriately designed studies are needed to guide tamponade selection.

Retina (Philadelphia, Pa.) May 2021To investigate the correlation between postoperative metamorphopsia and macular deformation after macular hole surgery.
PURPOSE
To investigate the correlation between postoperative metamorphopsia and macular deformation after macular hole surgery.
METHODS
This study included 28 eyes of 28 patients who underwent vitrectomy and internal limiting membrane removal for an idiopathic macular hole. The retinal vasculatures were compared between preoperative and postoperative photographs, and postoperative deformation of the macula was assessed as deformation of the square grid. The displacement of each node was measured, and deformation of the grid was calculated as differences in the coordinates of the adjacent nodes. These parameters were analyzed to find correlation with metamorphopsia measured using the M-charts after 6 postoperative months.
RESULTS
The average deformations in the vertical and horizontal lines of the grid were 94.29 μm and 49.72 μm, respectively. Perifoveal deformation was significantly greater than parafoveal deformation (P = 0.001∼0.019). The multiple regression analysis demonstrated that the vertical M-score correlated with superior perifoveal deformation of the vertical line on the fovea (P = 0.036), and the horizontal M-score correlated with temporal perifoveal deformation of the horizontal line on the fovea (P = 0.032).
CONCLUSION
The parafoveal tissue was displaced with the fovea concurrently after internal limiting membrane removal in macular hole surgery causing perifoveal deformation, which correlated with postoperative metamorphopsia.

BACKGROUND
The aim of this retrospective study was to evaluate commonly used clinical and OCT-morphological parameters, including perifoveal pseudocysts, as prognostic factors for postoperative outcome after macular hole surgery in a retinal referral clinic in North Rhine-Westphalia, Germany.
METHODS AND MATERIAL
This was a retrospective analysis of all patients who underwent surgery because of idiopathic MH between 2011 and 2017 in Augenklinik Tausendfensterhaus, Duisburg, Germany. Statistical evaluation of clinical and OCT-based parameters, including the areas of intraretinal pseudocysts, was conducted. The main statistical outcomes were surgical success and visual acuity. Only parameters with a highly significant correlation to the outcome parameters (postoperative visual acuity (VA); surgical success) in univariate analysis were entered in linear and logistic regression analyses.
RESULTS
A total of 189 eyes of 178 patients (71.4% female; mean age 67.5 ± 8.2 a) who underwent surgery because of MH were included. The overall closure rate was 86.8%. The mean best corrected VA increased from 0.7 ± 0.3 logMAR before surgery to 0.5 ± 0.3 logMAR (p < 0.0001). While several clinical and OCT-based parameters as well as calculated indices showed a significant correlation with the outcome measures, the regression analysis showed that the minimum linear diameter was the only parameter that both predicted surgical success (p = 0.015) and was correlated with postoperative VA (p < 0.001).
CONCLUSION
The minimum linear diameter serves as an easily assessed prognostic factor with the best predictive properties. This result is of great importance for clinical practice, as it simplifies the postsurgical prognosis.

Korean Journal of Ophthalmology : KJO Apr 2021To assess the prevalence and progression of a stage 0 macular hole in the fellow eye of patients with an idiopathic full-thickness macular hole.
PURPOSE
To assess the prevalence and progression of a stage 0 macular hole in the fellow eye of patients with an idiopathic full-thickness macular hole.
METHODS
The fellow eyes of 189 patients who underwent idiopathic full-thickness macular hole surgery were examined by biomicroscopy and spectral domain-optical coherence tomography (SD-OCT). A subset of 21 fellow eyes with a stage 0 macular hole was observed. Changes in the macular hole were evaluated by biomicroscopy and SD-OCT for an average of 29 months.
RESULTS
Among the 21 eyes, 15 showed no change in perifoveal vitreous detachment (71.4%). Two eyes (9.5%) developed complete vitreofoveal separation, and one of the two developed a separation after progression to stage 1A. Among 21 eyes, 5 (23.8%) developed above stage 1A, and one of the five progressed to stage 1B after five years, which was successfully treated with vitrectomy and gas tamponade.
CONCLUSIONS
Perifoveal vitreous detachment in the fellow eye on SD-OCT, defined as a stage 0 macular hole, occurred at an earlier phase than stage 1A macular holes and may progress to an advanced stage. Therefore, patients who undergo macular hole surgery and have a stage 0 macular hole or perifoveal vitreous detachment in the fellow eye should be followed closely.

PURPOSE
Epiretinal proliferation is a distinct clinical entity from epiretinal membrane that classically is associated with lamellar macular holes, but its prevalence and association with full-thickness macular holes (FTMH) have not been well described. We characterized macular hole-associated epiretinal proliferation (MHEP) and its effects on long-term surgical outcomes.
DESIGN
Multicenter, interventional, retrospective case-control study.
PARTICIPANTS
Consecutive eyes that underwent surgery for FTMH with a minimum of 12 months follow-up.
METHODS
All eyes underwent pars plana vitrectomy, removal of any epiretinal membranes, and gas tamponade, with or without internal limiting membrane (ILM) peeling. Spectral-domain OCT imaging was obtained before and after surgery.
MAIN OUTCOME MEASURES
Improvement in visual acuity and single-surgery hole closure rates in eyes with, versus without, MHEP at 12 months.
RESULTS
Seven hundred twenty-five charts were analyzed, and 113 patients met inclusion criteria. Of 113 eyes with FTMH, 30 (26.5%) showed MHEP. Patients with FTMH and MHEP were older (P < 0.002) and more often men (P = 0.001), and showed more advanced macular hole stages than those without MHEP (P = 0.010). A full posterior vitreous detachment was more common in eyes with MHEP (P < 0.004). Twelve months after surgery, FTMH with MHEP patients showed significantly less improvement in visual acuity (P = 0.019) with higher rates of ellipsoid and external limiting membrane defects (P < 0.05) and with a higher rate of failure to close with 1 surgery compared to FTMH without MHEP (26.7% vs. 4.8%; P = 0.002]). Peeling the ILM was associated with improved rates of hole closure in FTMH with MHEP (P < 0.001). Multivariate testing confirmed that the presence of MHEP was an independent risk factor for less visual improvement (P = 0.031) and for single-surgery nonclosure (P = 0.009) and that ILM peeling improved single-surgery closure rates (P = 0.026).
CONCLUSIONS
We found that FTMH with MHEP showed poorer anatomic and visual outcomes after vitrectomy compared with FTMH without MHEP. Internal limiting membrane peeling was associated with improved closure rates and should be considered when MHEP is detected before surgery.

Indian Journal of Ophthalmology Nov 2019To study the utility and predictive ability of newer macular hole (MH) indices for closure following surgery. (Comparative Study)
Comparative Study
PURPOSE
To study the utility and predictive ability of newer macular hole (MH) indices for closure following surgery.
METHODS
In this retrospective study, pre- and post-operative optical coherence tomography images of 49 eyes with idiopathic full-thickness MH were reviewed and analysed. Various quantitative parameters of MH like maximum outer diameter (OD), minimum diameter between edges, height, nasal and temporal arm lengths, macular hole angle were noted. Indices including hole form factor, Macular Hole Index, (MHI), Diameter Hole Index (DHI) and Tractional Hole Index (THI) were calculated. Newer area indices like macular hole area index (MAI), cystoid space area index (MCSAI) and tissue area index (MTAI) were calculated using Image J (Ver. 1.51). Receiver operating characteristic (ROC) curves and cut-off values were derived for indices predicting type 1 or type 2 closure. Stepwise regression analysis and binary logistic regression analysis were carried out to predict the chances of hole closure.
RESULTS
ROC curve analysis showed indices like MHI, THI and MCSAI were capable of successfully predicting type 1 closure while OD, DHI and MAI predicted type 2 closure. On stepwise regression analysis, MAI was identified as the most important index in predicting the type of hole closure. Using the binary logistic regression analysis, the predictive ability of the model to identify success or failure following MH surgery was 89.7% and 80% respectively.
CONCLUSION
MAI measurement could be used as a single important index in predicting hole closure in idiopathic MH. Further research is required to study this area index in detail.

BACKGROUND
The internal limiting membrane (ILM) insertion technique was widely used to treat large macular hole (MH) for the high closure rate. However, the prognosis of closed MH after ILM insertion compared to ILM peeling remains controversial. This study aimed to compare foveal microstructure and microperimeter in large idiopathic MH surgically closed by ILM peeling and ILM insertion.
METHODS
This retrospective, non-randomized, comparative study included patients with idiopathic MH (minimum diameter ≥ 650 μm) who underwent primary pars plana vitrectomy (PPV) with ILM peeling or ILM insertion. The initial closure rate was recorded. Patients with initially closed MHs were divided into two groups according to the surgery methods. The best-corrected visual acuity (BCVA), optical coherence tomography (OCT) and microperimeter-3 (MP-3) outcomes of two groups were compared at baseline, 1 and 4 months postoperatively.
RESULTS
For idiopathic MH (minimum diameter ≥ 650 μm), ILM insertion had a significantly higher initial closure rate than ILM peeling (71.19% vs. 97.62%, P = 0.001). Among 39 patients with initially closed MHs who were on regular follow-up, twenty-one were assigned to the ILM peeling group and 18 to the ILM insertion group. Postoperative BCVA improved significantly in both groups. The final BCVA (logMAR) (0.40 vs. 0.88, P < 0.001), macular hole sensitivity (19.66 dB vs. 14.14 dB, P < 0.001), peripheral sensitivity of macular hole (24.63 dB vs. 21.95 dB, P = 0.005), and fixation stability (FS) within 2 degrees (82.42% vs. 70.57%, P = 0.031) were significantly better and external limiting membrane (ELM) defect (330.14 μm vs. 788.28 μm, P < 0.001) and ellipsoid zone (EZ) defect (746.95 μm vs. 1105.11 μm, P = 0.010) were significantly smaller in the ILM peeling group than in the ILM insertion group.
CONCLUSION
For initially closed MHs (minimum diameter ≥ 650 μm), both ILM peeling and ILM insertion significantly improved the microstructure and microperimeter in the fovea. However, ILM insertion was less efficient at microstructural and functional recovery after surgery.

Meta-Analysis Review
Vitrectomy with internal limiting membrane peeling versus inverted internal limiting membrane flap technique for macular hole-induced retinal detachment: a systematic review of literature and meta-analysis.
BACKGROUND
To evaluate the effects on vitrectomy with internal limiting membrane (ILM) peeling versus vitrectomy with inverted internal limiting membrane flap technique for macular hole-induced retinal detachment (MHRD).
METHODS
Pubmed, Cochrane Library, and Embase were systematically searched for studies that compared ILM peeling with inverted ILM flap technique for macular hole-induced retinal detachment. The primary outcomes are the rate of retinal reattachment and the rate of macular hole closure 6 months later after initial surgery, the secondary outcome is the postoperative best-corrected visual acuity (BCVA) 6 months later after initial surgery.
RESULTS
Four studies that included 98 eyes were selected. All the included studies were retrospective comparative studies. The preoperative best-corrected visual acuity was equal between ILM peeling and inverted ILM flap technique groups. It was indicated that the rate of retinal reattachment (odds ratio (OR) = 0.14, 95% confidence interval (CI):0.03 to 0.69; P = 0.02) and macular hole closure (OR = 0.06, 95% CI:0.02 to 0.19; P < 0.00001) after initial surgery was higher in the group of vitrectomy with inverted ILM flap technique than that in the group of vitrectomy with ILM peeling. However, there was no statistically significant difference in postoperative best-corrected visual acuity (mean difference (MD) 0.18 logarithm of the minimum angle of resolution; 95% CI -0.06 to 0.43 ; P = 0.14) between the two surgery groups.
CONCLUSION
Compared with ILM peeling, vitrectomy with inverted ILM flap technique resulted significantly higher of the rate of retinal reattachment and macular hole closure, but seemed does not improve postoperative best-corrected visual acuity.

OBJECTIVE
Herein, we introduce the infusion direction manipulation technique and the infusion off technique. These relatively simple methods control intra-vitreal fluid flow direction and turbulence and release negative pressure in the microforceps to facilitate handling of the internal limiting membrane. The aim of this study is to introduce an effective and uncomplicated method to handle the internal limiting membrane (ILM) during the temporal inverted ILM flap and free ILM flap techniques in macular hole surgery by controlling the direction and status of the infusion.
MATERIALS AND METHODS
The direction of the infusion flow was controlled with a free finger (usually the 4th finger) during the inverted ILM flap surgery to stabilize the flap location during the fluid-air exchange. A valved trocar was used, and the infusion was discontinued during the free ILM flap surgery. Turbulence was minimized, and negative pressure around the head-shaft junction of the microforceps was released.
RESULTS
The ILM flap remained stable in all patients who underwent macular hole surgery with our technique.
CONCLUSIONS
Infusion direction manipulation technique and infusion off technique are efficient and simple methods to handle the ILM during ILM surgery.

Although ocular toxoplasmosis is usually a self-limiting infection, it can lead to severe reduction in visual acuity due to intense vitreous inflammation or involvement of posterior segment structures. Depending on the severity of intraocular inflammation, serious complications, including epiretinal membrane or retinal detachment may develop. In this paper, we aim to present a case that complicated by both a full-thickness macular hole and retinal detachment secondary to toxoplasmosis chorioretinitis that developed shortly after the novel coronavirus disease (COVID-19) and discuss our treatment approach. After the patient was diagnosed based on a routine ophthalmological examination, fundus imaging, and serological examination, functional and anatomical recovery was achieved through systemic antibiotherapy and vitreoretinal surgery. Full-thickness macular hole and retinal detachment are rare complications of ocular toxoplasmosis. However, there are only few publications in the literature concerning these complications and their surgical treatment. In this case report, we demonstrated the success of vitreoretinal surgery combined with antibiotic therapy on the posterior segment complications of ocular toxoplasmosis.
