    Area of Science:

    • Ophthalmology
    • Medical Imaging
    • Ultrasound Technology

    Background:

    • Accurate imaging of ocular structures is crucial for diagnosing and monitoring eye conditions.
    • Traditional imaging methods may have limitations in visualizing specific anterior and posterior segment structures.

    Purpose of the Study:

    • To evaluate the precision of high-frequency ultrasound for imaging key ocular structures.
    • To assess the utility of advanced ultrasound probes for enhanced visualization in glaucoma patients.

    Main Methods:

    • Utilized high-frequency ultrasound technology.
    • Employed a long-focus 20-MHz ultrasound probe for imaging.
    • Focused on imaging the iridocorneal angle, ciliary body, optic disk, and optic nerve.

    Main Results:

    • Achieved high-precision imaging of the iridocorneal angle and ciliary body.
    • Obtained high-resolution images of the optic disk and optic nerve.
    • Demonstrated increased precision in ultrasound imaging for glaucoma patients.

    Conclusions:

    • High-frequency ultrasound provides superior precision for imaging anterior segment structures like the iridocorneal angle and ciliary body.
    • A 20-MHz probe enables high-resolution visualization of posterior segment structures, including the optic nerve.
    • These ultrasound advancements enhance the diagnostic capabilities for patients with glaucoma.
