Color doppler blood flow analysis in circumscribed choroidal hemangioma

Area of Science:

• Ophthalmology
• Medical Imaging
• Vascular Biology

Background:

• Circumscribed choroidal hemangiomas are benign vascular tumors.
• Accurate diagnosis and assessment of vascularity are crucial for management.
• Color Doppler ultrasound is a non-invasive imaging modality.

Purpose of the Study:

• To evaluate the efficacy of color Doppler ultrasound in detecting internal blood flow within circumscribed choroidal hemangiomas.
• To determine if treatment status affects the detection of blood flow.

Main Methods:

• A cross-sectional study involving seven participants with circumscribed choroidal hemangiomas.
• B-scan ultrasound and color Doppler imaging were utilized.
• Assessment included lesion dimensions, location, and internal vascular flow.

Main Results:

• Color Doppler detected internal vascular flow in 100% of the evaluated circumscribed choroidal hemangiomas.
• Lesions averaged a diameter/thickness ratio >2 mm and thickness <5 mm.
• Predominant lesion locations were superior and supero-temporal.

Conclusions:

• Color Doppler ultrasound is a reliable method for detecting internal blood flow in circumscribed choroidal hemangiomas.
• The detection of blood flow by color Doppler is not influenced by the patient's treatment history.
