    Area of Science:

    • Ophthalmology
    • Optic Nerve Head Imaging
    • Glaucoma Diagnostics

    Context:

    • Accurate measurement of optic papilla and rim contours is crucial for diagnosing optic nerve disorders.
    • Photogrammetry offers reproducible results but is limited by biological noise.
    • Current methods struggle to improve precision beyond a certain threshold.

    Purpose:

    • To introduce and validate a dynamic test for assessing optic nerve head circulation.
    • To demonstrate the importance of measuring dynamic changes in optic disc pallor.
    • To overcome the limitations of static measurement methods in optic nerve head analysis.

    Summary:

    • A novel dynamic test measures optic disc pallor changes under artificially increased intraocular pressure.
    • This dynamic provoked circulatory response assesses the optic nerve head's response to pressure changes.
