Summary

Indocyanine-green (ICG) angiography shows promise for diagnosing inflammatory and neovascular choroidal diseases. While its value is limited in ischemic conditions and tumors, ICG angiography offers new insights into idiopathic conditions.

Area of Science:

  • Ophthalmology
  • Medical Imaging

Background:

  • Indocyanine-green (ICG) angiography has seen renewed interest due to technological advancements.
  • Digital imaging systems have improved the potential of ICG angiography.

Purpose of the Study:

  • To review the diagnostic value of ICG angiography in various choroidopathies based on extensive clinical experience.
  • To update on the applications of ICG angiography in ischemic, tumor, idiopathic, inflammatory, and neovascularized choroidal diseases.

Main Methods:

  • Review of 3,000 cases utilizing ICG angiography.
  • Evaluation of diagnostic utility across different categories of choroidal abnormalities.

Main Results:

  • ICG angiography has limited value in ischemic diseases due to poor imaging of the choriocapillaris.

Related Experiment Videos

  • The technique provides limited diagnostic information for choroidal tumors.
  • Valuable insights into the pathogenesis of idiopathic diseases were obtained.
  • Preliminary findings in inflammatory diseases are promising.
  • Significant advancements in imaging "occult"-choroidal neovascularization were achieved.

    • Conclusions:

    • ICG angiography is a valuable tool for specific choroidal diseases, particularly inflammatory and neovascular conditions.
    • Improved imaging of choroidal neovascularization facilitates ICG-guided laser treatment.
    • Further research is needed to enhance its utility in ischemic diseases and tumors.
