Colour Doppler imaging (CDI) assesses blood flow using ultrasound. This technique is valuable for diagnosing vascular conditions affecting the eye, optic nerve, and orbit.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Vascular Biology

Background:

  • Colour Doppler imaging (CDI) is an established ultrasonic method for blood flow assessment.
  • Recent advancements have enabled its application in evaluating orbital, optic nerve, and ocular vasculature.

Purpose of the Study:

  • To review the history, principles, and methodology of CDI in ophthalmology.
  • To describe normal hemodynamic characteristics and pathological findings in orbital blood flow disorders.

Main Methods:

  • Discussion of the principles and methodology of Colour Doppler imaging.
  • Review of haemodynamic characteristics in normal and pathological states.

Main Results:

  • CDI has demonstrated utility in ophthalmology for conditions with altered orbital, ocular, and optic nerve blood flow.

  • The technique provides qualitative and quantitative assessment of blood flow.

    • Conclusions:

    • CDI is a beneficial tool in ophthalmology for investigating vascular abnormalities.
    • Future applications of orbital CDI are expected to expand, particularly for vascular diseases of the orbit, optic nerve, and retina.
