Area of Science:

  • Ophthalmology and Genetics
  • Fibrotic matrix disorders
  • Ocular and Systemic Manifestations

Background:

  • Pseudoexfoliation (PEX) syndrome is a prevalent, age-related fibrotic matrix disorder with global health implications.
  • It is a significant cause of secondary glaucoma, cataract, and various intraocular complications.
  • Emerging evidence links PEX syndrome to systemic conditions, particularly cardiovascular and cerebrovascular diseases.

Purpose of the Study:

  • To present recent developments in pseudoexfoliation (PEX) syndrome.
  • To update on ocular and systemic manifestations, diagnosis, management, and molecular pathophysiology.
  • To identify future research directions and clinical challenges in PEX syndrome.

Main Methods:

  • Review of current scientific literature.

Related Experiment Videos

  • Analysis of authors' clinical and laboratory investigations.
  • Perspective-based synthesis of recent findings.

    • Main Results:

    • Improved clinical management through better understanding of PEX effects on ocular tissues, refined diagnostics, new treatments, and preventive strategies.
    • Growing evidence supports systemic associations of PEX syndrome with cardiovascular and cerebrovascular morbidity.
    • New insights into molecular pathophysiology, including PEX material composition, differential gene expression, and key pathogenetic factors like TGF-β1, oxidative stress, and impaired cellular protection.

    Conclusions:

    • Future research priorities include epidemiological and genetic studies for PEX syndrome prevalence.
    • Prospective studies are needed to investigate systemic manifestations and associations.
    • Intensified basic research on protein/gene expression, disease models, and biomarkers for PEX syndrome and associated glaucoma is crucial.
