Meta-Analysis Review
PURPOSE
Glaucoma is the leading cause of global irreversible blindness. Present estimates of global glaucoma prevalence are not up-to-date and focused mainly on European ancestry populations. We systematically examined the global prevalence of primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG), and projected the number of affected people in 2020 and 2040.
DESIGN
Systematic review and meta-analysis.
PARTICIPANTS
Data from 50 population-based studies (3770 POAG cases among 140,496 examined individuals and 786 PACG cases among 112 398 examined individuals).
METHODS
We searched PubMed, Medline, and Web of Science for population-based studies of glaucoma prevalence published up to March 25, 2013. Hierarchical Bayesian approach was used to estimate the pooled glaucoma prevalence of the population aged 40-80 years along with 95% credible intervals (CrIs). Projections of glaucoma were estimated based on the United Nations World Population Prospects. Bayesian meta-regression models were performed to assess the association between the prevalence of POAG and the relevant factors.
MAIN OUTCOME MEASURES
Prevalence and projection numbers of glaucoma cases.
RESULTS
The global prevalence of glaucoma for population aged 40-80 years is 3.54% (95% CrI, 2.09-5.82). The prevalence of POAG is highest in Africa (4.20%; 95% CrI, 2.08-7.35), and the prevalence of PACG is highest in Asia (1.09%; 95% CrI, 0.43-2.32). In 2013, the number of people (aged 40-80 years) with glaucoma worldwide was estimated to be 64.3 million, increasing to 76.0 million in 2020 and 111.8 million in 2040. In the Bayesian meta-regression model, men were more likely to have POAG than women (odds ratio [OR], 1.36; 95% CrI, 1.23-1.52), and after adjusting for age, gender, habitation type, response rate, and year of study, people of African ancestry were more likely to have POAG than people of European ancestry (OR, 2.80; 95% CrI, 1.83-4.06), and people living in urban areas were more likely to have POAG than those in rural areas (OR, 1.58; 95% CrI, 1.19-2.04).
CONCLUSIONS
The number of people with glaucoma worldwide will increase to 111.8 million in 2040, disproportionally affecting people residing in Asia and Africa. These estimates are important in guiding the designs of glaucoma screening, treatment, and related public health strategies.

Meta-Analysis
SIGNIFICANCE
This study summarized primary angle-closure glaucoma (PACG)-related factors across different dimensions.
OBJECTIVES
This review aimed at systematically summarizing the associated factors of PACG in published literatures.
METHODS
A systematic review and meta-analysis were conducted by searching the electronic databases including PubMed, EMBASE, and Web of Science from their inception to November 2021. The pooled risk estimates of continuous and categorical variables were calculated using weighted mean difference (WMD) and odds ratio (OR; 95% confidence intervals [CIs]), respectively.
RESULTS
We included 45 studies in this review. In the meta-analysis, intraocular pressure (WMD, 3.13; 95% CI, 2.37 to 3.89), anterior chamber depth (WMD, -0.52; 95% CI, -0.70 to -0.34), axial length (WMD, -0.77; 95% CI, -1.26 to -0.28), retinal nerve fiber layer (WMD, -21.23; 95% CI, -30.21 to -12.25), and spherical equivalent (WMD, 1.02; 95% CI, 0.66 to 1.38) were the most common ophthalmic anatomic factors, and lower body weight (WMD, -3.65; 95% CI, -6.48 to -0.82) was the most significant general morphological indicators. The presence of cataract (OR, 3.77; 95% CI, 3.46 to 4.11) and hyperlipidemia (OR, 1.10; 95% CI, 1.02 to 1.20) were significantly associated with PACG. Increased level of triglyceride (WMD, 0.17; 95% CI, 0.06 to 0.27) was associated with PACG. In addition, an association between short-term antidepressant exposure (OR, 1.36; 95% CI, 1.08 to 1.70) and acute angle-closure glaucoma was observed.
CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS
This review identified a few consistent factors related to PACG, providing important information for primary care physicians, general ophthalmologists, and public health professionals to counsel their patients on PACG risks.

Review
BACKGROUND
Currently, there is no generally approved surgical treatment for patients with primary angle-closure glaucoma (PACG) and co-existing cataracts. The aim of this systematic review and meta-analysis was to compare the efficacy and safety of phacoemulsification and phacotrabeculectomy in PACG patients with cataract.
METHODS
Diverse databases were searched, including PubMed, MEDLINE, EMBASE, Cochrane Library, Chinese Journal Full-text Database (CNKI), Wanfang database, and China Science and Technology Journal Database, for randomized controlled trials (RCTs) on phacoemulsification and phacotrabeculectomy for the treatment of PACG published up to 30 June 2021. ReviewManager (RevMan) version 5.4 software was used for the meta-analysis, and the effective quantity of measurement data was measured by the mean difference (MD) and 95% confidence interval (CI). The effect of counting data was measured by odds ratio (OR).
RESULTS
Our search of the databases identified 14 RCTs that satisfied the search criteria. Meta-analysis of these 14 RCTs showed that at the 1 month postoperative follow-up, intraocular pressure (IOP) of patients in the phacoemulsification group was higher than that of patients in the phacotrabeculectomy group (MD 2.04, 95% CI 1.42-2.65; P < 0.00001). However, the postoperative IOP was not significantly different between the two groups at the 3, 6, and 12 months postoperative follow-ups (P = 0.52, P = 0.51, and P = 0.05, respectively). More medications for IOP reduction were required by patients in the phacoemulsification group compared with those in the phacotrabeculectomy group at 3 months postoperation (MD 0.76, 95% CI 0.33-1.18; P = 0.0005), 6 months postoperation (MD 0.66, 95% CI 0.15-1.18; P = 0.01), and 12 months postoperation (MD 0.76, 95% CI 0.22-1.30; P = 0.006). Patients in the phacoemulsification group obtained better best corrected visual acuity (BCVA) than those in the phacotrabeculectomy group (MD - 0.17, 95% CI - 0.34 to - 0.01; P = 0.04) at 3 months postoperation, but there was no significant difference in BCVA between the two groups at 6 and 12 months postoperation (P = 0.33 and P = 0.56, respectively). The deepened anterior chamber was more obvious in patients in the phacoemulsification group versus those in the phacotrabeculectomy group (MD 0.61, 95% CI 0.03-1.18; P = 0.04). Patients in the phacoemulsification group experienced fewer postoperative complications than those in the phacotrabeculectomy group (OR 0.27, 95% CI 0.17-0.42; P < 0.00001).
CONCLUSION
Our results provide evidence that phacotrabeculectomy has advantages over phacoemulsification for the treatment of PACG in terms of better IOP and reduced medication need during the early stage post surgery. However, in terms of the complication risk, phacoemulsification is the more secure treatment option.

Meta-Analysis Review
BACKGROUND
Primary angle closure glaucoma (PACG) is higher in Asians than Europeans and Africans, with over 80% of PACG worldwide in Asia. Previous estimates of PACG were based largely on early studies, mostly using inappropriate case definitions. Therefore, we did a systematic review and meta-analysis to estimate the prevalence of PACG in adult Asian populations and to quantify its association with age, gender, and region.
METHODS
All primary reports of population-based studies that reported the prevalence of PACG in adult Asian populations were identified. PACG case definition was compatible with the ISGEO definition. Twenty-nine population-based studies were included. The overall pooled prevalence estimates were calculated using a random effect model, and ethnicity-, age- and gender-specific pooled prevalence estimates were also calculated.
RESULTS
The overall pooled prevalence of PACG in those of adult Asians was 0.75% (95% CI, 0.58, 0.96). Ethnicity-specific pooled prevalence estimates were 0.97% (0.22, 4.27) in Middle East group, 0.66% (0.23, 1.86) in South East Asia group, 0.46% (0.32, 0.64) in India group, 1.10% (0.85, 1.44) in China group, and 1.19% (0.35, 3.98) in Japan group, respectively. Age-specific prevalence was 0.21% (0.12, 0.37) for those 40-49 years, 0.54% (0.34, 0.85) for those 50-59 years, 1.26% (0.93, 1.71) for those 60-69 years, and 2.32% (1.74, 3.08) for those 70 years or above. The overall female to male ratio of the PACG prevalence was 1.51∶1 (95% CI 1.01, 2.28).
CONCLUSIONS
PACG affects approximately 0.75% adult Asians, increasing double per decade, and 60% of cases being female. The prevalence rates vary greatly by ethnic region.

BACKGROUND
Primary angle-closure glaucoma (PACG) is characterized by a rise in intraocular pressure (IOP) secondary to aqueous outflow obstruction, with relative pupillary block being the most common underlying mechanism. There is increasing evidence that lens extraction may relieve pupillary block and thereby improve IOP control. As such, comparing the effectiveness of lens extraction against other commonly used treatment modalities can help inform the decision-making process.
OBJECTIVES
To assess the effectiveness of lens extraction compared with other interventions in the treatment of chronic PACG in people without previous acute angle-closure attacks.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase, one other database, and two trials registers (December 2019). We also screened the reference lists of included studies and the Science Citation Index database. We had no date or language restrictions.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) comparing lens extraction with other treatment modalities for chronic PACG.
DATA COLLECTION AND ANALYSIS
We followed standard Cochrane methodology.
MAIN RESULTS
We identified eight RCTs with 914 eyes. We obtained data for participants meeting our inclusion criteria for these studies (PACG only, no previous acute angle-closure attacks), resulting in 513 eyes included in this review. The participants were recruited from a diverse range of countries. We were unable to conduct meta-analyses due to different follow-up periods and insufficient data. One study compared phacoemulsification with laser peripheral iridotomy (LPI) as standard care. Participants in the phacoemulsification group were less likely to experience progression of visual field loss (odds ratio [OR] 0.35, 95% confidence interval [CI] 0.13 to 0.91; 216 eyes; moderate certainty evidence), and required fewer IOP-lowering medications (mean difference [MD] -0.70, 95% CI -0.89 to -0.51; 263 eyes; moderate certainty evidence) compared with standard care at 12 months. Moderate certainty evidence also suggested that phacoemulsification improved gonioscopic findings at 12 months or later (MD -84.93, 95% CI -131.25 to -38.61; 106 eyes). There was little to no difference in health-related quality of life measures (MD 0.04, 95% CI -0.16 to 0.24; 254 eyes; moderate certainty evidence), and visual acuity (VA) (MD 2.03 ETDRS letter, 95% CI -0.77 to 4.84; 242 eyes) at 12 months, and no observable difference in mean IOP (MD -0.03mmHg, 95% CI -2.34 to 2.32; 257 eyes; moderate certainty evidence) compared to standard care. Irreversible loss of vision was observed in one participant in the phacoemulsification group, and three participants in standard care at 36 months (moderate-certainty evidence). One study (91 eyes) compared phacoemulsification with phaco-viscogonioplasty (phaco-VGP). Low-certainty evidence suggested that fewer IOP-lowering medications were needed at 12 months with phacoemulsification (MD -0.30, 95% CI -0.55 to -0.05). Low-certainty evidence also suggested that phacoemulsification may have improved gonioscopic findings at 12 months or later compared to phaco-VGP (angle grading MD -0.60, 95% CI -0.91 to -0.29; TISA500 MD -0.03, 95% CI -0.06 to -0.01; TISA750 MD -0.03, 95% CI -0.06 to -0.01; 91 eyes). Phacoemulsification may result in little to no difference in best corrected VA at 12 months (MD -0.01 log MAR units, 95% CI -0.10 to 0.08; low certainty evidence), and the evidence is very uncertain about its effect on IOP at 12 months (MD 0.50 mmHg, 95% CI -2.64 to 3.64; very low certainty evidence). Postoperative fibrin reaction was observed in two participants in the phacoemulsification group and four in the phaco-VGP group. Three participants in the phaco-VGP group experienced hyphema. No data were available for progression of visual field loss and quality of life measurements at 12 months. Two studies compared phacoemulsification with phaco-goniosynechialysis (phaco-GSL). Low-certainty evidence suggested that there may be little to no difference in mean IOP at 12 months (MD -0.12 mmHg, 95% CI -4.72 to 4.48; 1 study, 32 eyes) between the interventions. Phacoemulsification did not reduce the number of IOP-lowering medications compared to phaco-GSL at 12 months (MD -0.38, 95% CI -1.23 to 0.47; 1 study, 32 eyes; moderate certainty evidence). Three eyes in the phaco-GSL group developed hyphemas. No data were available at 12 months for progression of visual field loss, gonioscopic findings, visual acuity, and quality of life measures. Three studies compared phacoemulsification with combined phaco-trabeculectomy, but the data were only available for one study (63 eyes). In this study, low-certainty evidence suggested that there was little to no difference between groups in mean change in IOP from baseline (MD -0.60 mmHg, 95% CI -1.99 to 0.79), number of IOP-lowering medications at 12 months (MD 0.00, 95% CI -0.42 to 0.42), and VA measured by the Snellen chart (MD -0.03, 95% CI -0.18 to 0.12). Participants in the phacoemulsification group had fewer complications (risk ratio [RR] 0.59, 95% CI 0.34 to 1.04), and the phaco-trabeculectomy group required more IOP-lowering procedures (RR 5.81, 95% CI 1.41 to 23.88), but the evidence was very uncertain. No data were available for other outcomes.
AUTHORS' CONCLUSIONS
Moderate certainty evidence showed that lens extraction has an advantage over LPI in treating chronic PACG with clear crystalline lenses over three years of follow-up; ultimately, the decision for intervention should be part of a shared decision-making process between the clinician and the patient. For people with chronic PACG and visually significant cataracts, low certainty evidence suggested that combining phacoemulsification with either viscogonioplasty or goniosynechialysis does not confer any additional benefit over phacoemulsification alone. There was insufficient evidence to draw any meaningful conclusions regarding phacoemulsification versus trabeculectomy. Low certainty evidence suggested that combining phacoemulsification with trabeculectomy does not confer any additional benefit over phacoemulsification alone, and may cause more complications instead. These conclusions only apply to short- to medium-term outcomes; studies with longer follow-up periods can help assess whether these effects persist in the long term.

Meta-Analysis
Genome-wide association studies (GWAS) have identified that single-nucleotide polymorphisms (SNPs) rs1258267 in CHAT and rs3753841 in COL11A1 are associated with primary angle-closure glaucoma (PACG). The purpose of the study was to evaluate the association of CHAT rs1258267 and COL11A1 rs3753841 with PACG. A comprehensive electronic database search was performed to include eligible studies, published from October 2010 to March 2022. By calculating summary odds ratios (ORs) and 95% confidence intervals (CI) under five genetic models, the risk of PACG related to these two SNPs could be estimated. Heterogeneity was measured with a Chi-square-based Q statistic test and the I statistic. By the Z test, we analyzed the overall effect of OR. We used funnel plots and Begg's funnel plots to evaluate the publication bias of included studies. The meta-analysis was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 checklist. There were eighteen studies associating CHAT rs1258267 with PACG indicating evidently decreased PACG risk in five genetic models. Thirty studies were included to demonstrate a notable increase in the risk of PACG-carrying COL11A1 rs3753841 genotypes. Subgroup analyses showed that the association of CHAT rs1258267 and COL11A1 rs3753841 with PACG was obvious in Asians, while no evidence was found to confirm this connection in Caucasians. This meta-analysis suggests that CHAT rs1258267 G/A polymorphisms could bring about a decreased risk of PACG susceptibility and COL11A1 rs3753841 G/A polymorphisms could cause an increased risk. These effects mainly manifest in Asians.

Efficacy and Safety of Different Types of Intraocular Pressure-Lowering Surgeries in Patients with Primary Angle Closure (PAC) or PAC Glaucoma: Systematic Review and Network Meta-Analysis of Randomized Clinical Trials.
OBJECTIVE
To compare the intraocular pressure (IOP)-lowering effect of different types of surgery available in the literature using a network meta-analysis (NMA) based on a systematic review.
METHODS
PubMed and the Cochrane database were searched. Randomized clinical trials involving surgical interventions for high IOP for PAC (primary angle closure) or PACG (primary angle closure glaucoma) were included. Descriptive statistics and outcomes were extracted. Bayesian NMA was performed to compare the IOP-lowering effect and the change in the number of antiglaucoma drugs required between baseline and endpoint, as well as success rates.
RESULTS
This NMA included 21 articles with 1237 eyes with PAC or PACG. Interventions were characterised as phacoemulsification (phaco), trabeculectomy, goniosynechialysis (GSL) with viscoelastic or blunt device, goniosurgery (GS) (trabeculotomy or goniotomy), micro-bypass stent (Istent®), endocyclophotocoagulation (ECPL) or various combinations of these procedures. Phaco+GSL [-1.73 (95%CrI: -3.53 to -0.13)] and phaco+GSL+GS [-3.92 (95%CrI: -6.91 to -1.31)] provided better IOP lowering effects than phaco alone. Phaco+trabeculectomy [-3.11 (95%CrI: -5.82 to -0.44)] was inferior to phaco+GSL+GS. Phaco+trabeculectomy [-0.45 (95%CrI: -0.81 to -0.13)] provided a better outcome in terms of reducing the need for antiglaucoma drug compared to phaco alone. There were no differences between the other surgeries in terms of reduction of antiglaucoma drug number and IOP lowering effect. Success rates were similar for all surgical procedures.
CONCLUSIONS
Phaco+GSL+GS showed the most promising results for lowering IOP. Phaco+trabeculectomy resulted in a significant reduction in the number of antiglaucoma drugs compared to phaco alone.

This meta-analysis aims to investigate the worldwide prevalence of primary angle-closure glaucoma (PACG) and its risk factors in the last 20 years. We conducted a systematic review and meta-analysis of 37 population-based studies and 144,354 subjects. PubMed, Embase, and Web of Science databases were searched for cross-sectional or cohort studies published in the last 20 years (2000-2020) that reported the prevalence of PACG. The prevalence of PACG was analyzed according to various risk factors. A random-effects model was used for the meta-analysis. The global pooled prevalence of PACG was 0.6% [95% confidence interval (CI) = 0.5-0.8%] for the last 20 years. The prevalence of PACG increases with age. Men are found less likely to have PACG than women (risk ratio = 0.71, 95% CI = 0.53-0.93, < 0.01). Asia is found to have the highest prevalence of PACG (0.7%, 95% CI = 0.6-1.0%). The current estimated population with PACG is 17.14 million (95% CI = 14.28-22.85) for people older than 40 years old worldwide, with 12.30 million (95% CI = 10.54-17.57) in Asia. It is estimated that by 2050, the global population with PACG will be 26.26 million, with 18.47 million in Asia. PACG affects more than 17 million people worldwide, especially leading a huge burden to Asia. The prevalence of PACG varies widely across different ages, sex, and population geographic variation. Asian, female sex, and age are risk factors of PACG.

Review
Iridoschisis is a rare condition defined as a separation of the anterior iris stroma from the posterior stroma and muscle layers. In this paper, we review current data about the epidemiology, pathophysiology, clinical characteristics and differential diagnoses of this condition and discuss the specificity of surgical treatment of concomitant ocular diseases in iridoschisis patients. Iridoschisis may pose a challenge for both an ophthalmologist in an outpatient setting and an ophthalmic surgeon. Glaucoma, primarily angle-closure glaucoma, is the most often described condition concomitant to iridoschisis. Other ocular abnormalities found relatively often in iridoschisis patients include cataract, lens subluxation and corneal abnormalities. Special attention has been paid to potential complications of cataract surgery and prevention thereof. Beside addressing the practical aspects, we point to discrepancies and suggest topics for further investigation.

Ophthalmology Jun 2016Systematic review and meta-analysis of the genetic associations of primary angle-closure disease (PACD). (Meta-Analysis)
Meta-Analysis Review
TOPIC
Systematic review and meta-analysis of the genetic associations of primary angle-closure disease (PACD).
CLINICAL RELEVANCE
To confirm the genetic biomarkers for PACD, including primary angle-closure glaucoma (PACG) and related phenotypes.
METHODS
We searched in the MEDLINE and EMBASE databases for genetic studies of PACG or other PACD published from the start dates of the databases to May 11, 2015. We estimated the summary odds ratios (ORs) and 95% confidence intervals (CIs) for each polymorphism in PACG, primary angle-closure suspect (PACS), and primary angle-closure (PAC) using fixed- or random-effect models. We also performed sensitivity analysis to test the robustness of the results.
RESULTS
Our literature search yielded 6463 reports. Among them, we identified 24 studies that fulfilled the eligibility criteria for meta-analysis, involving 28 polymorphisms in 11 genes/loci. We affirmed the association of PACG and combined PACS/PAC/PACG with 10 polymorphisms in 8 genes/loci, including COL11A1 (rs3753841-G, OR, 1.22; P = 0.00046), HGF (rs17427817-C, OR, 2.02; P = 6.9E-07; rs5745718-A, OR, 2.11; P = 9.9E-07), HSP70 (rs1043618, GG+GC, OR, 0.52; P = 0.0010), MFRP (rs2510143-C, OR, 0.66; P = 0.012; rs3814762-G, OR, 1.40; P = 0.0090), MMP9 (rs3918249-C, OR, 1.35; P = 0.034), NOS3 (rs7830-A, OR, 0.80; P = 0.036), PLEKHA7 (rs11024102-G, OR, 1.24; P = 8.3E-05), and PCMTD1-ST18 (rs1015213-A, OR, 1.59; P = 0.00013). Sensitivity analysis indicated that the results were robust.
CONCLUSIONS
In this study, we confirmed multiple polymorphisms in 8 genes/loci as genetic biomarkers for PACD, among which 3 were identified in a genome-wide association study (COL11A1, PLEKHA7, and PCMTD1-ST18), and 5 were identified in candidate gene studies (HGF, HSP70, MFRP, MMP9, and NOS3).
