Summary

Indocyanine green (ICG) angiography reveals distinct patterns in multifocal choroiditis, differentiating active and inactive stages. This imaging technique aids in understanding the inflammatory process and choroidal neovascularization in this condition.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Immunology

Background:

  • Multifocal choroiditis is an inflammatory eye condition affecting the choroid.
  • Accurate diagnosis and understanding of disease patterns are crucial for effective management.
  • Limitations of traditional imaging methods necessitate advanced techniques for comprehensive evaluation.

Purpose of the Study:

  • To retrospectively analyze indocyanine green (ICG) angiographic features in patients with multifocal choroiditis.
  • To identify and characterize distinct angiographic patterns associated with active and inactive disease stages.
  • To evaluate the utility of ICG angiography in assessing choroidal involvement and neovascularization.

Main Methods:

  • Retrospective analysis of ICG angiography in 13 patients diagnosed with multifocal choroiditis.

  • Comparison of ICG findings with ophthalmoscopy and fluorescein angiography.
  • Categorization of angiographic features into 'active' and 'inactive' patterns.

    • Main Results:

    • Two distinct ICG angiographic patterns were identified: 'active' and 'inactive'.
    • The 'active' pattern demonstrated persistent hypofluorescence and more extensive choroidal involvement than initially presumed.
    • The 'inactive' pattern showed stable hypofluorescence, with no new lesions appearing over time. Choroidal neovascularization was observed in 10 patients, predominantly in the inactive stage.

    Conclusions:

    • ICG angiography provides valuable insights into the pathophysiology of multifocal choroiditis.
    • The identified patterns aid in differentiating active from inactive disease phases.
    • Findings support the hypothesis that inflammatory involvement of the choriocapillaris underlies multifocal choroiditis.
