    Assessing cerebrovascular reactivity can be done by observing pial vessel calibre changes. Preliminary experiments show that increased intraocular pressure in normal individuals causes retinal vasodilatation.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Vascular Biology

    Background:

    • Pial vessel calibre changes are a reliable indicator of cerebrovascular reactivity.
    • Accurate in situ measurements of vessel calibre are crucial for this assessment.
    • The Baez image splitting television technique offers a refined method for rapid and precise measurements.

    Purpose of the Study:

    • To apply the Baez technique to measure retinal vessel calibre in vivo.
    • To investigate the relationship between intraocular pressure and retinal vascular response.
    • To assess cerebrovascular reactivity in the context of ocular physiology.

    Main Methods:

    • Utilized the Baez image splitting television technique for in situ vessel calibre measurement.
    • Applied the technique to the readily accessible retinal vasculature of the eye.

  • Conducted preliminary experiments on normal human subjects.

    • Main Results:

    • The Baez technique was successfully applied to retinal vessels.
    • An induced increase in intraocular pressure was correlated with retinal vasodilatation.
    • Preliminary data suggests a link between elevated intraocular pressure and vascular response in the retina.

    Conclusions:

    • The Baez technique is a viable method for assessing vascular calibre in the retina.
    • Increased intraocular pressure may induce a vasodilatory response in retinal vessels.
    • This study provides preliminary evidence for using retinal vascular changes to infer cerebrovascular reactivity.
