Meta-Analysis Review
PURPOSES
The purposes of this study were to (i) determine macular hole (MH) closure rates and visual outcomes by comparing two methods of managing traumatic MH (TMH)-an event resulting in severe loss of visual acuity (VA); (ii) characterize patients who undergo spontaneous TMH closure; (iii) determine which TMH patients should be observed before resorting to surgical repair; and (iv) elucidate factors that influence postoperative visual outcomes.
METHODS
Studies (n=10) of patients who were managed by surgery or observation for TMH were meta-analyzed retrospectively. Management modalities included surgical repair (surgery group) and observation for spontaneous hole closure (observation group). In addition, a 12-case series of articles (1990-2014) on spontaneous hole closure was statistically summarized. SAS and Comprehensive Meta-Analysis (CMA) (version 3.0) were used for analysis.
RESULTS
For surgery group patients, the fixed-model pooled event rate for hole closure was 0.919 (range, 0.861-0.954) and for observation group patients, 0.368 (range, 0.236-0.448). The random-model pooled event rate for improvement of visual acuity (VA) for surgery group patients was 0.748 (range, 0.610-0.849) and for observation group patients, 0.505 (range, 0.397-0.613). For patients in both groups, the mean age of spontaneous closure was 18.71±10.64 years; mean size of TMHs, 0.18±0.06 decimal degrees (DD); and mean time for hole closure, 3.38±3.08 months. The pooled event rate for visual improvement was 0.748 (0.610-0.849).
CONCLUSIONS
Hole closure and VA improvement rates of surgery group patients were significantly higher than those for observation group patients. Patients of ≤ 24 years of age with MH sizes of ≤ 0.2DD were more likely to achieve spontaneous hole closure. The interval of time from injury to surgery was statistically significantly associated with the level of visual improvement.

Review
PURPOSE
The optimal management of pediatric traumatic macular holes (TMH) is unclear from lack of prospective randomized trials. The literature is divided into early (≤1month post-trauma), delayed (>1 month) pars plana vitrectomy (PPV), and observation. Our aim is to find which group can achieve best-superior spectacle corrected visual acuity (VA), visual gain, and time for hole closure.
DESIGN
Systematic review.
METHODS
This systematic review was registered with PROSPERO (ID:CRD42022383134). The databases searched from inception until July 31, 2023, were MEDLINE OVID, Scopus, Web of Science, Embase, and Google Scholar. The articles were screened for title and abstract then for full text. Risk of bias was also assessed. Three outcome measures were analyzed: final VA, visual gain, and time to closure of macular hole (MH). MH size was divided into small (≤250 µm), medium (>250-500 µm), and large (>500 µm).
RESULTS
Ninety eight (98) studies with 234 patients in the PPV group and 87 patients in the observation group were included in the review. Final VA (logarithm of the minimum angle of resolution) and visual gain were respectively in PPV vs observation groups: (1) small MH 0.37 ± 0.52 vs 0.42 ± 0.56 (P = .484) and -0.96 ± 0.83 vs -0.49 ± 0.40 (P = .005); (2) medium MH 0.58 ± 0.39 vs 0.34 ± 0.34 (P = .06) and -0.36 ± 0.42 vs -0.74 ± 0.44 (P < .001); (3) large MH 0.62 ± 0.42 vs 0.59 ± 0.35 (P = .337) and -0.31 ± 0.48 vs -0.62 ± 0.37 (P = .11). Small TMH had comparable closure time: 3.21 ± 2.52 months vs 3.49 ± 4.43 (P = .954) in the PPV and observation groups. Early and late PPV yielded comparable final VA 0.67 ± 0.66 vs 0.54 ± 0.35 (P = .576) and visual gain -0.58 ± 0.69 vs -0.49 ± 0.48 (P = .242) in the PPV and observation groups.
CONCLUSIONS
PPV was very effective in closing TMH and VA gain in children throughout a wide range of hole size. Early and delayed PPV yielded similar anatomic and visual results. Observation and PPV yielded comparable final VA and closure time. Clinicians can choose either early PPV or delayed PPV when healing biomarkers are absent on periodic optical coherence tomography.

Meta-Analysis Review
PURPOSE
The treatment of refractory macular holes is controversial, with human amniotic membrane grafts emerging recently as an attractive option. We performed a meta-analysis and systematic review in this paper to assess the results of human amniotic membrane (hAM) in the treatment of refractory macular hole (MH).
METHODS
We searched the Cochrane Database of Systematic Reviews, Web of Science, PubMed, Embase, China National Knowledge Infrastructure databases, VIP database, Wanfang Data Knowledge Service Platform, Sinomed, Chinese Clinical Trial Registry, and Clinical Trials.gov. Studies reporting hAM for the treatment of refractory MH were included. The outcomes are MH closure rate, visual acuity (VA) improvement rate, and graft dislocation/contracture rate.
RESULTS
A total of 8 studies on 103 eyes were included, all of which had undergone failed vitrectomy and internal limiting membrane (ILM) peeling. In all studies, the VA improvement rate was 66% (95%CI: 45 to 84%), the MH closure rate was 94% (95%CI: 84 to 100%) and the hAM graft dislocation/contracture rate was 6% (95%CI: 0 to 15%). In the studies using cryopreserved hAM grafts, the MH closure rate was 99% (95%CI: 94 to 100%) and the hAM graft dislocation/contracture rate was 3% (0%, 10%). The VA improvement rates were 94% (95%CI: 79 to 100%) in the retinal detachment subgroup, 37% (95%CI: 20 to 56%) in the pathologic myopia subgroup, and 62% (95%CI: 14 to 100%) in the idiopathic MH subgroup.
CONCLUSION
Human amniotic membrane in the treatment of refractory MH results in visual improvement. It has a high macular hole closure rate and low dislocation/contracture rate. Cryopreserved hAM grafts might have better outcomes than dehydrated grafts.

Meta-Analysis Review
TOPIC
The importance of postoperative face-down positioning (FDP) to achieve anatomic and functional success after full-thickness macular hole (FTMH) surgery is explored in this meta-analysis of randomized controlled trials (RCTs).
CLINICAL RELEVANCE
There is considerable variability in clinical practices regarding the need and length of FDP recommended to patients after FTMH surgery. There is also a lack of robust clinical guidelines on the topic. As such, an updated estimate of the effect size of FDP on clinically important outcomes is critical to inform practice.
METHODS
Ovid MEDLINE, EMBASE, CENTRAL, and SCOPUS databases were searched from inception to October 3, 2021, for RCTs evaluating FDP versus non-FDP (nFDP). Data were collected for 7 clinically important outcomes after macular hole surgery: closure rate, visual acuity (VA) improvement, recurrence of FTMH, visual function, quality of life, patient satisfaction, and complication rates. We used the Cochrane risk-of-bias tool for randomized trials (RoB 2) to assess the risk of bias and followed the Grade of Recommendations, Assessment, Development, and Evaluation (GRADE) approach to assess the certainty in the evidence across outcomes. We conducted meta-analyses using random-effects modeling. Subgroup analyses were carried out based on hole size, type of gas, and duration of FDP.
RESULTS
Eight RCTs of 709 eyes were included. The relative risk (RR) of FTMH closure rate comparing FDP versus nFDP was RR 1.05 (95% confidence interval [CI]: 0.99, 1.12, P = 0.09, I = 44%, GRADE rating: LOW). The mean difference (MD) regarding VA improvement comparing FDP and nFDP was MD -0.07 (95% CI: -0.12 to 0.01, P = 0.03, I = 16%, GRADE rating: LOW).
CONCLUSION
The current review did not demonstrate a difference between FDP and nFDP with respect to FTMH closure, although the CIs were wide. There was a visual benefit to FDP; however, the CIs included values of trivial clinical significance. Subgroup analyses demonstrated that the VA benefit observed was driven by large holes. Limited data precluded analysis regarding the rate of FTMH recurrence, measures of visual function, quality of life measures, and patient satisfaction metrics. Further prospective trials are required to assess the gaps in the literature and improve the certainty of evidence for the outcomes examined.

Ophthalmology. Retina Aug 2023Comparing the efficacy and safety between combined and sequential pars plana vitrectomy and phacoemulsification for macular hole (MH) and epiretinal membrane (ERM). (Meta-Analysis)
Meta-Analysis Review
TOPIC
Comparing the efficacy and safety between combined and sequential pars plana vitrectomy and phacoemulsification for macular hole (MH) and epiretinal membrane (ERM).
CLINICAL RELEVANCE
The standard of care for MH and ERM is vitrectomy, which increases the risk of developing cataract. Combined phacovitrectomy eliminates the need for a second surgery.
METHODS
Ovid MEDLINE, EMBASE, and Cochrane CENTRAL were searched in May 2022 for all articles comparing combined versus sequential phacovitrectomy for MH and ERM. The primary outcome was mean best-corrected visual acuity (BCVA) at 12 months follow-up. Meta-analysis was conducted using a random effects model. Risk of bias (RoB) was assessed using the Cochrane RoB 2 tool for randomized controlled trials (RCTs) and Risk of Bias in Nonrandomized Studies of Interventions tool for observational studies (PROSPERO, registration number, CRD42021257452).
RESULTS
Of the 6470 studies found, 2 RCTs and 8 nonrandomized retrospective comparative studies were identified. Total eyes for combined and sequential groups were 435 and 420, respectively. Meta-analysis suggested no significant difference between combined and sequential surgery for 12-month BCVA (combined = 0.38 logarithm of the minimum angle of resolution [logMAR]; sequential = 0.36 logMAR; mean difference = + 0.02 logMAR; 95% confidence interval = -0.04 to 0.08; P = 0.51; I = 0%; n = 4 studies, 398 participants), as well as absolute refractive error (P = 0.76; I = 97%; n = 4 studies, 289 participants), risk of myopia (P = 0.15; I = 66%; n = 2 studies, 148 participants), MH nonclosure (P = 0.57; I = 48%; n = 4 studies, 321 participants), cystoid macular edema (P = 0.15; I = 0%; n = 6 studies, 526 participants), high-intraocular pressure (P = 0.09; I = 0%; n = 2 studies, 161 participants), posterior capsule opacification (P = 0.46; I = 0%; n = 2 studies, 161 participants), posterior capsule rupture (P = 0.41; I = 0%; n = 5 studies, 455 participants), and retinal detachment (P = 0.67; I = 0%; n = 6 studies, 545 participants).
CONCLUSION
No significant difference was detected between combined and sequential surgeries for visual outcomes, refractive outcomes, or complications. Given that most studies were retrospective and contained a high RoB, future high-quality RCTs are warranted.

This systematic review and meta-analysis aimed to determine the traumatic macular hole (TMH) closure rate and visual acuity (VA) improvement rate by comparing two treatment methods for TMH: vitrectomy and observation for spontaneous closure. PubMed, Cochrane, Web of Science Library, Embase, CNKI, Wanfang, VIP, and Sino Med were systematically searched from their inception to June 10, 2021. Studies in the surgery group ( = 32) and studies in the observation group ( = 12) were meta-analyzed. The primary outcomes were the TMH closure and VA improvement rates in the surgery and observation groups. The secondary outcomes were best-corrected visual acuity (BCVA) improvement in the surgery group. Stata software (version 15.1) was used for the analyses. Thirty-six studies that included 1,009 eyes were selected for this meta-analysis, among which 33 were retrospective studies and 3 were prospective studies. The meta-analysis showed that the random-model pooled event rate for TMH closure was 0.37 (95% confidence interval [CI], 0.26-0.48) in the observation group, while it was 0.9 (95% CI, 0.85-0.94) in the surgery group. The fixed-model pooled event rate for VA improvement was 0.39 (95% CI, 0.33-0.45) in the observation group, while the random-model pooled event rate of VA improvement for the surgery group was 0.72 (95% CI, 0.63-0.80). The pooled event rate for BCVA improvement in the surgery group was 0.39 (95% CI, 0.33-0.46). This meta-analysis suggests that TMH hole closure and VA improvement rates in the surgery group were significantly higher than those in the observation group. Vitrectomy is an effective method for treating TMH. However, further randomized controlled trials (RCTs) are required to evaluate the efficacy and safety of surgery and observation for TMH treatment. https://www.crd.york.ac.uk/PROSPERO/#recordDetails, identifier: CRD42021276684.

Review
BACKGROUND
Lamellar macular holes (LMHs) are small, partial-thickness defects of the macula defined by characteristic features on optical coherence tomography (OCT), including a newly recognised type of epiretinal membrane termed 'epiretinal proliferation'. There may be a rationale to recommend surgery for individuals with LMHs, particularly those with functional or anatomical deterioration, or poor baseline vision causing significant disability, to stabilise the LMH and prevent further visual deterioration; however, there is currently no evidence-based consensus.
OBJECTIVES
To assess the effect of surgical interventions on post-operative visual and anatomical outcomes in people with a confirmed LMH.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE Ovid, Embase Ovid, Scopus SciVerse, ISRCTN registry, US National Institutes of Health Ongoing Trials Register, ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). We also searched reference lists of included trials to identify other eligible trials which our search strategy may have missed. The date of the search was 20 July 2021.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) involving participants with a confirmed LMH diagnosis which reported one or more surgical intervention(s), alone or in combination, in at least one arm of the RCT.
DATA COLLECTION AND ANALYSIS
We used standard methods as expected by Cochrane. Two study authors independently extracted data and assessed the risk of bias for included trials. Trial authors were contacted for further information and clarification.
MAIN RESULTS
A single RCT was eligible for inclusion. Thirty-six participants were randomised in a 2:1 ratio; 24 were allocated to undergo surgery (pars plana vitrectomy, peeling of the epiretial proliferation followed by fovea-sparing removal of the internal limiting membrane) and 12 (10 following two participant dropouts) to observation. Overall, the certainty of the evidence was low for all outcomes due to selection and detection bias, and the low number of participants enrolled in the study which may affect the accuracy of results and reliability of conclusions. At six-month follow-up, change in vision was better in the surgery group (-0.27 logMAR improvement) than observation (0.02 worsening) (mean difference (MD): -0.29 logMAR, 95% confidence intervals (CI): -0.33 to -0.25). Central retinal thickness increased in the surgery group over 6 months 126 μm increase) compared with observation group (decrease by 11μm) (MD: 137 μm, 95% CI: 125.87 μm to 148.13 μm). Finally, at six-month follow-up, retinal sensitivity was better in the surgery group (3.03 dB increase) compared with the observation group (0.06 dB decrease) (MD: 3.09 dB, 95% CI: 2.07 to 4.11 dB). Vision-related quality of life and metamorphopsia were not reported. No adverse outcomes or complications were reported in the study, however, authors could not provide information on whether any individuals developed deterioration in vision of 0.2 logMAR or worse.
AUTHORS' CONCLUSIONS
The included single trial demonstrated improvements in visual and anatomical outcome measures for participants with a LMH who underwent surgery compared with observation only. Therefore, we can conclude that participants who undergo surgery may achieve superior post-operative best corrected visual acuity and anatomical outcomes compared with observation only. However, the results of a single and small RCT provides limited evidence to support or refute surgery as an effective management option for LMHs. Future RCTs with a larger number of participants and with fewer methodological limitations and biases are necessary to inform future clinical practice.

Meta-Analysis Review
PURPOSE
To assess the literature regarding macular hole reopening rates stratified by whether the internal limiting membrane (ILM) was peeled during vitrectomy surgery.
METHODS
Systematic review and meta-analysis of studies reporting on macular hole reopenings among previously surgically closed idiopathic macular holes. A comprehensive literature search using the National Library of Medicine PubMed interface was used to identify potentially eligible publications in English. The minimum mean follow-up period for reports to be included in this study was 12 months. Analysis was divided into eyes that underwent vitrectomy with and without ILM peeling. The primary outcome parameter was the proportion of macular hole reopenings among previously closed holes between the two groups. Secondary outcome parameters included duration from initial surgery to hole reopening and preoperative and postoperative best-corrected correct visual acuities among the non-ILM peeling and ILM peeling groups.
RESULTS
A total of 50 publications reporting on 5,480 eyes met inclusion criteria and were assessed in this meta-analysis. The reopening rate without ILM peeling was 7.12% (125 of 1,756 eyes), compared with 1.18% (44 of 3,724 eyes) with ILM peeling (odds ratio: 0.16; 95% confidence interval: 0.11-0.22; Fisher's exact test: P < 0.0001). There were no other identifiable associations or risk factors for reopening.
CONCLUSION
The results of this meta-analysis support the concept that ILM peeling during macular hole surgery reduces the likelihood of macular hole reopening.

Meta-Analysis Review
Ocriplasmin for treatment of vitreomacular traction and macular hole: A systematic literature review and individual participant data meta-analysis of randomized, controlled, double-masked trials.
Ocriplasmin is used to treat vitreomacular traction (VMT), with or without full-thickness macular hole (MH). We systematically reviewed the evidence on ocriplasmin's effect on vitreomacular adhesion resolution (VMAR), MH closure, vitrectomy, and best-corrected visual acuity (BCVA) and investigated the effect of baseline covariates on outcome. We applied individual participant data meta-analyses to the entire population and to subgroups defined by MH or epiretinal membrane (ERM) presence. Safety data were pooled and tabulated. Five randomized controlled trials (1,067 participants) were included. Six months after treatment, ocriplasmin achieved higher rates of VMAR and MH closure versus control, lowered vitrectomy odds, and increased the likelihood of a ≥10-letter BCVA increase. VMAR rates were lower when ERM, broad VMA (> 1500 µm), diabetic retinopathy, or pseudophakia were present and higher in younger participants, women, and eyes with MHs. Ocriplasmin-treated participants experienced more short-term visual impairment that was not predictive of final BCVA, as well as vitreous floaters, photopsia, photophobia, eye pain, blurred vision, and dyschromatopsia. The most common serious adverse events for ocriplasmin and control, respectively, were MH progression (22.5%, 17.3%), new MH (1.5%, 3.4%) and retinal detachment (0.8%, 1.2%). Ocriplasmin promotes VMAR and MH closure. Transient visual phenomena are not uncommon.

Meta-Analysis Review
BACKGROUND
A macular hole is an anatomic opening in the retina that develops at the fovea. Macular holes can be seen in highly myopic eyes or following ocular trauma, but the great majority are idiopathic. Pars plana vitrectomy was introduced to treat full-thickness macular holes, which if left untreated have a poor prognosis since spontaneous closure and visual recovery are rare.Vitrectomy is a surgical technique involving the removal of the vitreous body that fills the eye. The surgeon inserts thin cannulas into the eyes through scleral incisions to relieve traction exerted by the vitreous or epiretinal membranes to the central retina and to induce glial tissue to bridge and close the hole.
OBJECTIVES
The primary objective of this review was to examine the effects of vitrectomy for idiopathic macular hole on visual acuity. A secondary objective was to investigate anatomic effects on hole closure and other dimensions of visual function, as well as to report on adverse effects recorded in included studies.
SEARCH METHODS
We searched the Cochrane Eyes and Vision Group Trials Register (4 March 2015), the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 2), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to March 2015), EMBASE (January 1980 to March 2015), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to March 2015), the Web of Science Conference Proceedings Citation Index-Science (CPCI-S) (January 1980 to March 2015), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 4 March 2015.
SELECTION CRITERIA
We included randomised controlled trials comparing vitrectomy (with or without internal limiting membrane peeling) to no treatment (that is observation) for macular holes.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. Two review authors independently extracted the data. We estimated best corrected visual acuity and macular hole closure at 6 to 12 months of follow-up.
MAIN RESULTS
Three studies provided data on the comparison between vitrectomy and observation in eyes with macular hole and visual acuity less than 20/50. Two studies, conducted in the USA and published in 1996 and 1997, used a similar protocol and included participants with stage II macular hole (42 eyes randomised, 36 analysed, number of participants not reported) or participants with stage III/IV hole (129 eyes of 120 participants, 115 eyes in analyses). The third study, conducted in the UK and published in 2004, included 185 eyes of 174 participants with full-thickness macular hole (41 eyes with stage II holes and 74 eyes with stage III/IV holes in analyses). Studies were of good quality for randomisation and allocation concealment, whereas visual acuity measurement was unmasked.At 6 to 12 months, visual acuity was improved by about 1.5 Snellen lines (-0.16 logMAR, 95% confidence intervals -0.23 to -0.09 logMAR, 270 eyes, moderate-quality evidence). The chances of macular hole closure at 6 to 12 months were greatly increased using vitrectomy, yielding an odds ratio of 31.4 (95% confidence intervals 14.9 to 66.3, 265 eyes, high-quality evidence; raw sum data: 76% vitrectomy, 11% observation). Vitrectomy was beneficial both in smaller (stage II) and in larger (stage III/IV) macular holes.The largest study reported that cataract surgery was needed in about half of cases at two years after operation and that retinal detachment occurred in about 5% of operated eyes.
AUTHORS' CONCLUSIONS
Vitrectomy is effective in improving visual acuity, resulting in a moderate visual gain, and in achieving hole closure in people with macular hole. However, these results may not apply to modern surgery due to technological improvements in vitrectomy techniques.
