|June 1, 1979
Summary
Fluorescein angiography aids in diagnosing iris tumors. This technique reveals dye leakage in malignant melanomas and fluorescence blockage in melanocytomas, guiding clinical evaluation.
Area of Science:
- Ophthalmology
- Medical Imaging
- Oncology
Background:
- Pigmented iris tumors require accurate diagnostic methods.
- Fluorescein angiography is a valuable tool for evaluating intraocular lesions.
Observation:
- Three cases of pigmented iris tumors were examined using fluorescein angiography.
- Specific patterns of dye leakage and fluorescence blockage were observed.
Findings:
- Malignant melanomas showed early dye leakage during the arterial phase.
- A melanocytoma presented with fluorescence blockage.
Implications:
- The angiographic findings correlate with known patterns of similar fundus lesions.
- Fluorescein angiography is recommended for all pigmented iris tumors to aid diagnosis.
