PURPOSE: To evaluate if color Doppler can detect internal blood flow in circumscribed choroidal hemangioma.
METHODS: This cross-sectional study examined seven eyes of seven participants with circumscribed choroidal hemangiomas, with or without prior treatment. B-scan ultrasound and color Doppler were used to assess the dimensions, topographical distribution, and internal blood flow of the affected eyes.
RESULTS: The sample included seven patients (five female) with a median age of 61 (62.29 ± 13.83) years. There were seven eyes with circumscribed choroidal hemangiomas in the patient sample. Color Doppler detected internal vascular flow in all cases (100%). The lesions had an average diameter/thickness ratio of >2 mm and an average thickness of <5 mm and were predominantly located superiorly and supero-temporally.
CONCLUSION: Internal blood flow was detected in circumscribed choroidal hemangiomas using color Doppler. Detection was unaffected by the patient's treatment status.
