Corneal Stiffness Parameters Are Predictive of Structural and Functional Progression in Glaucoma Suspect Eyes.

Glaucoma suspect eyes with higher corneal SPs and lower CCT, suggestive of thin and stiff corneas, are at greater risk of progression.

An Intraocular Pressure Polygenic Risk Score Stratifies Multiple Primary Open-Angle Glaucoma Parameters Including Treatment Intensity.

The IOP PRS was correlated positively with maximum IOP, disease severity, need for surgery, and number of affected family members.

SVEP1 as a Genetic Modifier of TEK-Related Primary Congenital Glaucoma.

We provide further evidence for PCG caused by TEK haploinsufficiency, affirm autosomal dominant inheritance in two pedigrees, and propose SVEP1 as a modifier of TEK expression during SC development, affecting disease penetrance and severity.

Prevalence of FOXC1 Variants in Individuals With a Suspected Diagnosis of Primary Congenital Glaucoma.

These data highlight the genetic and phenotypic heterogeneity of childhood glaucoma and support the use of gene panels incorporating FOXC1 as a diagnostic aid, especially because clinical features of Axenfeld-Rieger syndrome can be subtle.

Biallelic CPAMD8 Variants Are a Frequent Cause of Childhood and Juvenile Open-Angle Glaucoma.

Biallelic CPAMD8 variation was associated with a highly heterogeneous phenotype and in our cohorts was the second most common inherited cause of childhood glaucoma after CYP1B1 and juvenile open-angle glaucoma after MYOC.

Myocilin Gene Gln368Ter Variant Penetrance and Association With Glaucoma in Population-Based and Registry-Based Studies.

The MYOC p.Gln368Ter variant confers a very high-risk effect size for advanced glaucoma; the risk is lower in nonadvanced glaucoma and OHT.

Childhood and Early Onset Glaucoma Classification and Genetic Profile in a Large Australasian Disease Registry.

We report on the largest cohort of individuals with childhood and early onset glaucoma from Australasia using the CGRN classification.

Association Between Body Mass Index and Primary Open Angle Glaucoma in Three Cohorts.

Body mass index correlated with longitudinal and cross-sectional glaucomatous outcomes. This supports previous work illustrating a correlation between BMI and glaucoma.

Association of High Polygenic Risk With Visual Field Worsening Despite Treatment in Early Primary Open-Angle Glaucoma.

In this study, high polygenic risk was associated with more rapid structural and functional progression in early POAG, despite more intensive treatment.

Association of Monogenic and Polygenic Risk With the Prevalence of Open-Angle Glaucoma.

Monogenic and high polygenic risk were each associated with a more than 2.5-fold increased odds of developing glaucoma and an equivalent mean age at glaucoma diagnosis, with high polygenic risk more than 15 times more…

Attitudes Towards Polygenic Risk Testing in Individuals with Glaucoma.

These findings will help to facilitate the clinical implementation of PRS testing for glaucoma to reduce irreversible vision loss.

High Polygenic Risk Is Associated with Earlier Initiation and Escalation of Treatment in Early Primary Open-Angle Glaucoma.

This study demonstrated novel associations between glaucoma polygenic risk and risk of commencement or escalation of IOP-lowering therapy, building on previous work highlighting the potential clinical usefulness of genetic risk stratification in glaucoma.

Contribution of Mutations in Known Mendelian Glaucoma Genes to Advanced Early-Onset Primary Open-Angle Glaucoma.

Rare, potentially disease-causing variants in Mendelian POAG genes that showed enrichment in our dataset were found in 22.9% of advanced early-onset POAG cases.

A Polygenic Risk Score Predicts Intraocular Pressure Readings Outside Office Hours and Early Morning Spikes as Measured by Home Tonometry.

A validated IOP PRS was associated with higher early morning IOP and mean IOP outside office hours.

Comparison of Anterior Segment Abnormalities in Individuals With FOXC1 and PITX2 Variants.

Corneal abnormalities were more common in individuals with FOXC1 than in those with PITX2 variants and were often associated with early onset glaucoma.

A Multitrait Open-Angle Glaucoma Polygenic Risk Score Stratifies Risk of Glaucoma Diagnosis and Severity in Eyes with Pseudoexfoliation.

The PRSs for open-angle glaucoma, IOP, and VCDR stratify risk of glaucoma development and disease severity among individuals with PEX.

Attitudes Toward Glaucoma Genetic Risk Assessment in Unaffected Individuals.

Our results show strong interest in genetic risk assessment for glaucoma among unaffected individuals in Australia.

Physical Activity Is Associated With Macular Thickness: A Multi-Cohort Observational Study.

These results highlight the potential neuroprotective benefits of exercise on the human retina.

High Polygenic Risk Is Associated with Earlier Trabeculectomy in Patients with Primary Open-Angle Glaucoma.

This report identified clinically relevant correlations between glaucoma PRS and the need for surgical intervention in patients with glaucoma.

Uptake of Polygenic Risk Testing for Glaucoma in Unaffected Individuals.

This is the first study to demonstrate the potential uptake of polygenic testing for glaucoma among an unaffected population.

A Multitrait Polygenic Risk Score for Open-Angle Glaucoma Stratifies Risk of Pigmentary Glaucoma in Pigment Dispersion Syndrome.

A multitrait PRS for open-angle glaucoma stratifies risk of glaucoma onset and disease severity among individuals with PDS.

Healthcare professionals' knowledge and attitudes towards polygenic risk testing for glaucoma.

Our findings indicated that multiple groups of healthcare professionals were neither familiar nor confident with the concept of glaucoma polygenic risk testing, and identified training and education needs to support the implementation of testing into…

Occurrence of CYP1B1 Mutations in Juvenile Open-Angle Glaucoma With Advanced Visual Field Loss.

Patients with advanced JOAG based on visual field loss had enrichment of CYP1B1 pathogenic variants and a more severe phenotype compared with unaffected controls and patients with nonadvanced JOAG.

Copy number variations of TBK1 in Australian patients with primary open-angle glaucoma.

We report the presence of TBK1 copy number variations in our Australian normal-tension glaucoma cohort, including the first example of more than 1 extra copy of this gene in glaucoma patients (gene triplication).
