New thoughts on ocular neovascularization: a neurally controlled regenerative process?

G H Cassel, L R Groden

    Annals of Ophthalmology
    |February 1, 1984
    PubMed
    Summary

    Ocular neovascularization, or new blood vessel growth in the eye, may be a neurally mediated regenerative process. This concept is supported by regeneration parallels in lower vertebrates and studies on ocular tissues.

    Area of Science:

    • Ophthalmology
    • Regenerative Medicine
    • Neuroscience

    Background:

    • Ocular neovascularization is a common pathway for various eye diseases, but its unifying mechanism remains unclear.
    • Regeneration in lower vertebrates shares similarities with ocular neovascularization, suggesting potential shared pathways.
    • Neural factors are known to play a role in regeneration in other biological models.

    Purpose of the Study:

    • To explore the concept of ocular neovascularization as a neurally mediated regenerative process.
    • To investigate the role of neural factors in the pathogenesis of new blood vessel growth in the eye.
    • To provide a unifying mechanism for ocular neovascularization based on regenerative principles.

    Main Methods:

    • Review of developmental associations and clinical observations related to ocular neovascularization.
    • Analysis of regeneration models in lower vertebrates.
    • Examination of evidence from ocular tissues like the iris, lens, and neural retina.
    • Consideration of recent research involving corneal denervation models.

    Main Results:

    • Ocular tissues demonstrate remarkable regenerative potential, aligning with neural mediation.
    • Parallels between vertebrate regeneration and ocular neovascularization suggest a common underlying mechanism.
    • Corneal denervation studies provide further support for the neural involvement in ocular vascularization.

    Conclusions:

    • Ocular neovascularization can be conceptualized as a neurally mediated regenerative process.
    • Neural factors are critically important in the pathogenesis of new blood vessel growth in the eye.
    • This perspective offers a unifying hypothesis for understanding and potentially treating ocular neovascularization.
