PRECIS
This systematic review and meta-analysis found that 360° selective laser trabeculoplasty (SLT) is significantly more effective than 180° SLT at reducing intraocular pressure at one month and one year follow-ups, without increased serious adverse event risk.
PURPOSE
To determine the efficacy of 180° versus 360° selective laser trabeculoplasty (SLT) in adults with open angle glaucoma (OAG) and ocular hypertension (OHT).
METHODS
A systematic review was performed using PubMed, Embase, and Scopus databases, from 1995 to December 30, 2023, for studies comparing 180° and 360° SLT in adults with OAG and OHT (PROSPERO ID: CRD42024497832). Meta-analyses were performed to calculate nominal percent and raw reductions in IOP between treatment groups at one-month, one-year, and two-year follow-ups, as well as success rates, defined as a 20% or greater IOP reduction.
RESULTS
Nine studies with 1044 eyes were included; 491 received 180°SLT and 553 received 360° SLT. At the one-month follow-up, 360° SLT reduced IOP by 3.45% more (WMD=3.45; 95% CI: 2.02-4.88; P<0.00001) and 0.87 mmHg more (WMD=0.87; 95% CI: 0.35-1.38; P=0.0010). At the one-year follow-up, 360° SLT reduced IOP by 4.33% more (WMD=4.33; 95% CI: 2.35-6.32; P<0.0001) and 1.15 mmHg more (WMD=1.15; 95% CI: 0.25-2.04; P=0.01). At two years of follow up, 360° SLT reduced IOP by 4.86% more (WMD=4.86; 95% CI: -0.32, 10.0; P=0.07) and 1.25 mmHg more (WMD=1.25; 95% CI: -0.29, 2.79; P=0.11), however the difference was not statistically significant. Compared to 360° SLT, 180° SLT had a significantly lower success rate (OR=0.50; 95% CI: 0.35-0.72; P=0.0002). There was no difference in serious complications between interventions.
CONCLUSION
360° SLT is more effective than 180° SLT at lowering IOP at one-month and one-year follow-ups as well as achieving successful IOP control without increased risk of serious complications.

Meta-Analysis
PRCIS
This systematic review and meta-analysis concludes that the PreserFlo Microshunt glaucoma drainage device significantly reduces intraocular pressure in primary open angle glaucoma patients at 12 months postinsertion.
PURPOSE
A systematic review and meta-analysis on the effect of the PRESERFLO MicroShunt (PF-MS) on intraocular pressure (IOP) at 12 months has been conducted.
METHOD
The PubMed/MEDLINE, Embase, CENTRAL, Google Scholar, Scopus, and Web of Science databases were searched. Inclusion criteria required a diagnosis of open angle glaucoma, PF-MS insertion, and examination of IOP over time. Meta-analyses were conducted on the primary outcome of IOP and the secondary outcome of glaucoma medication regime. Adverse events were also noted.
RESULTS
Fourteen studies were identified for inclusion in the meta-analyses, of which none had a high risk of bias. The meta-analyses found a significant mean reduction in IOP of 9.07 mm Hg (95% CI: 7.88-10.25; P <0.0001) and a significant mean reduction in mean glaucoma medication requirement of 2.37 medications (95% CI: 2.15-2.60; P <0.0001). Hypotony and hyphaema are common early complications.
CONCLUSIONS
The PF-MS device significantly reduced both IOP and glaucoma medication requirement at 12 months postinsertion in individuals with open angle glaucoma without a significant adverse event burden. Further research is required to determine the economic and environmental effects of widely implementing the PF-MS device into clinical practice.

Comparative Study
Age is an important risk factor for both glaucoma and cataract. As global life expectancy continues to rise, the prevalence of concomitant open-angle glaucoma (OAG) and cataracts is increasing. Currently, there is a lack of definitive consensus on the optimal management approach for such individuals. Conventionally, trabeculectomy (Trab) in combination with phacoemulsification is the preferred method. Recent developments in microinvasive glaucoma surgery (MIGS), which offer similar results with fewer complications, provide a new possible approach to this condition. This study aimed to assess the current knowledge of combination surgery in patients with cataract and OAG to provide a comprehensive understanding and help its implementation in clinical settings. A comprehensive systematic search was conducted in May 2021 on five databases (MEDLINE, Embase, SCOPUS, Proquest, EBSCO, and Cochrane Library). The results were filtered for English and human studies but not publication year. All studies published up to May 2021 were reviewed. Newcastle-Ottawa Scale and PEDro scale were used to screen studies for risk of bias where appropriate. Four studies satisfied the inclusion criteria and were subsequently added in this review. Study designs consisted of one RCT and three descriptive studies. Appropriate assessment tools were used; these studies demonstrated moderate to good quality. Postoperative mean IOP, IOP reduction, and qualified success rates were comparable in the Phaco-MIGS (Phaco-endoscopic cyclophotocoagulation (ECP), Phaco-ab interno trabeculectomy (AIT)) and Phaco-Trab group. Severe complication was reported only in the latter. Phaco-MIGS (in particular, trabectome) shows excellent promise as an option for individuals with OAG and concomitant cataract; further research through RCT is required to validate these findings.

Review
To investigate the relationship between glaucoma, pseudoexfoliation and hearing loss (HL). : A systematic literature search following PRISMA guidelines was conducted using the PubMed, Embase, Scopus and Cochrane databases from 1995 up to 28 August 2023. : Thirty studies out of the 520 records screened met the inclusion criteria and were included. Most articles (n = 20) analysed the association between pseudoexfoliation syndrome (XFS) and HL, showing XFS patients to have higher prevalence of sensorineural hearing loss (SNHL) at both speech frequencies (0.25, 0.5, 1 and 2 kHz), and higher frequencies (4 and 8 kHz) compared to controls in most cases. No significant differences in prevalence or level of HL between XFS and pseudoexfoliative glaucoma (XFG) were detected in most studies. Eight articles analysed the relationship between primary open-angle glaucoma (POAG) and HL. Overall, a positive association between the two conditions was highlighted across all studies except for two cases. Similarly, articles focusing on NTG and HL (n = 4) showed a positive association in most cases. The role of autoimmunity and, in particular, the presence of antiphosphatidylserine antibodies (APSA) in patients with NTG and HL suggested an underlying autoimmune or vascular mechanism contributing to their pathogenesis. Only one study analysed the relationship between angle-closure glaucoma (ACG) and HL, showing higher incidence of ACG in patients with SNHL compared to normal hearing controls. : Most studies detected an association between XFS and HL as well as POAG/NTG/ACG and HL, suggesting the presence of a similar pathophysiology of neurodegeneration. However, given the strength of the association of XFS with HL, it remains unclear whether the presence of XFG is further associated with SNHL. Further research specifically targeted to assess the correlation between glaucoma, XFS and HL is warranted to provide a more comprehensive understanding of this association.

PRECIS
There is evidence that cataract surgery can reduce intraocular pressure in patients with primary open angle-, normal tension-, or exfoliative glaucoma. The complete effect of phacoemulsification is masked by topical intraocular pressure-lowering medications.
PURPOSE
To assess the impact of phacoemulsification and intraocular lens implantation on intraocular pressure (IOP) level in individuals with primary open-angle glaucoma (POAG), exfoliative glaucoma (XFG), exfoliation syndrome (XFS), normal tension glaucoma (NTG), ocular hypertension (OH) or healthy controls 12 months after the surgery.
METHODS
In July 2023, a comprehensive literature review was conducted across six databases. The analysis focused on the phacoemulsification arms of randomized controlled trials (RCTs). The primary outcome of interest was the mean IOP change observed 12 months after phacoemulsification.
RESULTS
This meta-analysis included nine arms from nine RCTs, comprising a total of 502 participants. Overall, the average IOP was reduced by 3.77 mmHg (95%CI: -5.55 to -1.99, I2=67.9%) 12 months after surgery. The subgroup analysis, focused on whether a washout period was employed before measuring IOP, revealed that studies with a washout period exhibited a more pronounced IOP reduction of 5.25 mmHg (95%CI: -7.35 to -3.15, I2=0%), while studies without a washout period exhibited a reduction of 3.13 mmHg (95%CI: -5.46 to -0.81, I2=75.8%). The sensitivity analysis for the latter group, excluding an outlier study, showed a reduction of 1.81 mmHg (95%CI: -2.95 to -0.67, I2=0%).
CONCLUSIONS
The findings of this systematic review and meta-analysis indicate that cataract surgery meaningfully lowers IOP in POAG, XFG/XFS, or OH 12 months after surgery. However, the use of topical medications masks the precise impact of phacoemulsification upon postoperative IOP. Further research using appropriate washout periods is warranted.

Review
In order to support the positioning of Rho kinase inhibitors (Rhokis) in the European market for the treatment of glaucoma, scientific evidence comparing the efficacy and safety of Rhokis and beta-blockers (β-βs) in the treatment of open-angle glaucoma after 3 months was assembled through a systematic review and meta-analysis (meta-A) of randomized controlled trials (RCTs). Relevant articles were searched for on PubMed, EMBASE, and the Cochrane Library. Of the 251 articles found, three met all eligibility criteria. These three articles were assessed for risk of bias. Data were extracted and a random effects meta-A was performed. The studies' methods were homogeneous but there was great heterogeneity within the data (I = 92-93%; < 0.001). All studies had low risk of bias. The meta-A showed statistically better efficacy of β-βs, resulting in an intraocular pressure (IOP) reduction mean difference of 1.73 (1.19-2.27) at 8 a.m., 0.66 (0.19-1.15) at 10 a.m. and 0.49 mmHg (0.001-0.98) at 4 p.m., compared to Rhokis. This difference is not clinically significant as intra-operator variability of IOP measurements varies from ±2 to ±3 mmHg The adverse effects of Rhokis were essentially topical, whereas β-βs mainly caused systemic side effects. This Meta-A showed that Rhokis are clinically non-inferior to beta-blockers in reducing IOP. Rhokis have a better safety profile.

Review
TOPIC
To investigate differences in peripapillary choroidal thickness (PPCT) between primary open-angle glaucoma (POAG), normal tension glaucoma (NTG), and healthy eyes, additionally comparing differences between POAG and NTG eyes.
CLINICAL RELEVANCE
Peripapillary choroidal thickness is a well-established OCT parameter in eyes with glaucoma and other ocular pathologies. The relationship between PPCT and glaucoma, if better understood, may facilitate the development of PPCT as a potential diagnostic and monitoring metric for glaucoma. In particular, there has yet to be a synthesis that directly compares PPCT between POAG eyes and NTG eyes.
METHODS
A comprehensive literature search was performed on PubMed, EMBASE, and Cochrane Library, identifying studies from inception to December 2022. We included studies that measured PPCT using OCT in POAG, NTG, and healthy eyes. Mean difference (MD) among groups was calculated. Statistical analysis was performed using R version 4.2.0. Risk of bias of included studies was assessed using the Newcastle Ottawa Scale (NOS).
RESULTS
Eighteen studies were included in this meta-analysis, with a pooled total of 935 healthy control eyes, 446 NTG eyes, and 934 POAG eyes. There was a significant reduction of PPCT in POAG eyes compared with healthy eyes [MD = -16.32; 95% confidence interval (CI) (-27.55 to -5.09)]. Reduction in PPCT was also significant in NTG eyes compared with healthy eyes [MD = -34.96; 95% CI (-49.97 to -19.95)]. NTG eyes had significantly reduced PPCT compared with POAG eyes [MD = -26.64; 95% CI (-49.00 to -4.28)].
CONCLUSIONS
Glaucomatous eyes appear to have significantly reduced PPCT compared with normal healthy eyes. In addition, PPCT in NTG eyes appear significantly thinner compared with that in POAG eyes.

Many forms of childhood glaucoma have been associated with underlying genetic changes, and variants in many genes have been described. Currently, testing is variable as there are no widely accepted guidelines for testing. This systematic review aimed to summarize the literature describing genetic changes and testing practices in childhood glaucoma. This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic review and Meta-Analyses (PRISMA) 2020 guidelines and registered with Prospero (ID CRD42023400467). A comprehensive review of Pubmed, Embase, and Cochrane databases was performed from inception through March 2, 2023 using the search terms: (glaucoma) AND (pediatric OR childhood OR congenital OR child OR infant OR infantile) AND (gene OR genetic OR genotype OR locus OR genomic OR mutation OR variant OR test OR screen OR panel). Information was extracted regarding genetic variants including genotype-phenotype correlation. Risk of bias was assessed using the Newcastle-Ottawa Scale. Of 1,916 records screened, 196 studies met inclusion criteria and 53 genes were discussed. Among study populations, mean age±SD at glaucoma diagnosis was 8.94±9.54 years and 50.4% were male. The most common gene discussed was CYP1B1, evaluated in 109 (55.6%) studies. CYP1B1 variants were associated with region and population-specific prevalence ranging from 5% to 86% among those with primary congenital glaucoma. MYOC variants were discussed in 31 (15.8%) studies with prevalence up to 36% among patients with juvenile open angle glaucoma. FOXC1 variants were discussed in 25 (12.8%) studies, which demonstrated phenotypic severity dependent on degree of gene expression and type of mutation. Overall risk of bias was low; the most common domains of bias were selection and comparability. Numerous genes and genetic changes have been associated with childhood glaucoma. Understanding the most common genes as well as potential genotype-phenotype correlation has the potential to improve diagnostic and prognostic outcomes for children with glaucoma.
