Diagnosing extramacular disciform lesions requires differentiating them from uveal tumors. Clinical evaluation, ultrasonography, and angiography can accurately identify these lesions, aiding in diagnosis.

Area of Science:

  • Ophthalmology
  • Medical Imaging

Background:

  • Extramacular disciform lesions can mimic uveal tumors.
  • Accurate differentiation is crucial for appropriate patient management.

Purpose of the Study:

  • To identify distinguishing features of extramacular disciform lesions using clinical, ultrasonographic, and fluorescein angiographic methods.
  • To differentiate these lesions from uveal tumors.

Main Methods:

  • Retrospective study of 19 patients with suspected malignancy.
  • Evaluation included clinical assessment, ultrasonography, and fluorescein angiography.

Main Results:

  • Diagnostic accuracy: clinical (79%), ultrasonography (83%), angiography (83%).
  • Fluorescein angiography utility was limited by media opacities in some cases.

  • No intraocular malignancies developed during follow-up.

    • Conclusions:

    • Noninvasive techniques, particularly ultrasonography and angiography, are effective in diagnosing extramacular disciform lesions.
    • A combined approach enhances diagnostic accuracy.
