    A novel hypothesis suggests lens tension influences ocular hypertension and glaucoma. Equatorial zonules are active in accommodation, while anterior and posterior zonules provide passive lens support.

    Area of Science:

    • Ophthalmology
    • Biomechanics
    • Anatomy

    Background:

    • The function of zonular fibers in the human eye is not fully understood.
    • Current understanding of ocular hypertension and open-angle glaucoma lacks a comprehensive explanation of zonular involvement.

    Purpose of the Study:

    • To propose a new hypothesis regarding zonular function.
    • To explore the implications of this hypothesis for the cause and treatment of ocular hypertension and open-angle glaucoma.

    Main Methods:

    • Conceptual analysis of ocular anatomy and physiology.
    • Review of existing literature on lens mechanics and accommodation.

    Main Results:

    • The lens is hypothesized to be under constant tension.

  • Anterior and posterior zonules primarily provide passive structural support to the lens.
  • Equatorial zonules are proposed as the active components responsible for accommodation.

    • Conclusions:

    • This hypothesis offers a new perspective on the role of zonular fibers in maintaining ocular health.
    • Understanding zonular function may lead to novel therapeutic strategies for ocular hypertension and open-angle glaucoma.
