Control of blood vessel development

R W Bellhorn

    Transactions of the Ophthalmological Societies of the United Kingdom
    |September 1, 1980
    PubMed
    Summary

    Understanding ocular tissue metabolic demands is key to preventing vision loss from vascular retinopathies. Research in animal models and human eyes is needed to control blood vessel development and disease.

    Area of Science:

    • Ophthalmology
    • Vascular Biology
    • Retinal Research

    Background:

    • Ocular tissue metabolic demands influence blood vessel structure and function.
    • Alterations in these demands, during maturation or disease, change vessel permeability and morphology.
    • These changes underlie vision-threatening complications in vascular retinopathies.

    Purpose of the Study:

    • To understand the environmental factors determining normal and abnormal ocular blood vessel morphology and permeability.
    • To investigate the relationship between tissue environment and blood vessel development in various retinal vascularization states and disease models.

    Main Methods:

    • Studying animals with fully, partially, or non-vascularized retinae.
    • Examining animals with experimental retinopathies.
    • Evaluating these relationships in human eyes with and without vascular abnormalities.

    Main Results:

    • Metabolic demands are critical determinants of ocular blood vessel characteristics.
    • Disease processes significantly alter vessel morphology and permeability.
    • Understanding these inter-relationships is essential for controlling pathological angiogenesis.

    Conclusions:

    • Further investigation into ocular tissue environmental factors is necessary.
    • Comparative studies in animal models and human eyes are crucial.
    • This knowledge is fundamental to preventing and managing vision loss from vascular retinopathies.
