Article Synopsis
  • * Conducted as a prospective cohort study, it involved 1,107 participants with varying degrees of glaucoma severity, who were either treatment naive or already receiving treatment at enrollment.
  • * Results indicated that a higher PRS significantly increased the likelihood of starting IOP-lowering therapy within 5 years and also led to a higher chance of treatment escalation for those already undergoing therapy.

Article Synopsis
  • The study aimed to investigate the relationship between the apolipoprotein E (E4) allele and the prevalence of glaucoma in large genetic cohorts, including data from over 438,000 participants in the UK Biobank and several other studies.* -
  • Results indicated that the E4 allele was inversely associated with glaucoma and negative control conditions like cataract and diabetic eye disease in the UK Biobank, suggesting a potential protective effect.* -
  • However, a separate association was found linking Alzheimer's dementia (AD) with both glaucoma and cataract, indicating complexities in the relationship between E4 and these eye conditions, with replication analyses failing to confirm initial findings.*

Purpose: associated ectopia lentis is a rare autosomal recessive condition that is primarily associated with crystalline lens displacement. However, the prevalence of other ocular and systemic manifestations of this condition is poorly understood. In this study, we summarize the ocular and systemic phenotypic spectrum of this condition.

Purpose: To investigate the association between the apolipoprotein E () E4 dementia-risk allele and prospective longitudinal retinal thinning in a cohort study of suspect and early manifest glaucoma.

Design: Retrospective analysis of prospective cohort data.

Participants: This study included all available eyes from participants recruited to the Progression Risk of Glaucoma: Relevant SNPs [single nucleotide polymorphisms] with Significant Association (PROGRESSA) study with genotyping data from which genotypes could be determined.

Purpose: To evaluate the association between genetic risk for cardiovascular disease and retinal thinning in early glaucoma.

Design: Prospective, observational genetic association study.

Participants: Multicohort study combining a cohort of patients with suspect and early manifest primary open-angle glaucoma (POAG), a cohort of patients with perimetric POAG, and an external normative control cohort.

Objective: Childhood glaucoma is a chronic vision-threatening condition that may significantly impact an individual's psychosocial well-being. There is a paucity of literature investigating the quality of life (QoL) in children with glaucoma. The aim of this study was to investigate and report on the QoL issues encountered by children with glaucoma.

Purpose: Axenfeld-Rieger syndrome encompasses a group of developmental disorders affecting the anterior chamber structures of the eye, with associated systemic features in some cases. This study aims to compare the difference in anterior segment phenotypes such as those involving the cornea, iris, lens, and anterior chamber angle between cases with disease-causing sequence variations in FOXC1 and PITX2 .

Methods: This cross-sectional study involved 61 individuals, from 32 families with pathogenic FOXC1 or PITX2 variants, who were registered with the Australian and New Zealand Registry of Advanced Glaucoma.

Purpose: Pseudoexfoliation syndrome (PEX) is a common systemic disease that results in severe and often irreversible vision loss. Despite considerable research effort, PEX remains incompletely understood. This study sought to perform the first RNAseq study in elucidate the pathophysiology of PEX, and contribute a publicly available transcriptomic data resource for future research.

Purpose: To investigate and report on the quality-of-life (QoL) issues experienced by caregivers of individuals with childhood glaucoma.

Design: Exploratory, qualitative study.

Participants: Thirty-five caregivers of individuals with childhood glaucoma (defined as disease onset before 18 years of age) recruited from the Australian and New Zealand Registry of Advanced Glaucoma.

Purpose: To report the relative frequencies of childhood and early onset glaucoma subtypes and their genetic findings in a large single cohort.

Design: Retrospective clinical and molecular study.

Participants: All individuals with childhood glaucoma (diagnosed 0 to <18 years) and early onset glaucoma (diagnosed 18 to <40 years) referred to a national disease registry.

Background: Ocular coherence tomography angiography (OCTA) is available in varying size and resolution. We sought to characterise associations of cardiometabolic factors with retinal microvascular changes using 3 × 3, 6 × 6 and 8 × 8-mm OCTA scans to determine differences in detection with varying scan size.

Methods: Cross-sectional study of 247 cardiovascular patients from a single-centre tertiary-care hospital.

Purpose: To investigate corneal stiffness parameters (SPs) as predictors of future progression risk in glaucoma suspect eyes.

Design: Prospective, longitudinal study.

Participants: Three hundred seventy-one eyes from 228 primary open-angle glaucoma suspects, based on optic disc appearance, with normal baseline Humphrey Visual Field (HVF; Carl Zeiss Meditec) results.

Article Synopsis
  • * A study assessed 11 facial traits in 34 individuals with the syndrome, finding common features like a thin upper lip and prominent forehead, but specific traits varied significantly between the two gene mutations.
  • * The results can help clinicians make better diagnoses and offer more accurate genetic counseling to affected families.
