PURPOSE: To demonstrate the utility of orbital ultrasound in the evaluation and management of suspected orbital vascular lesions. METHODS: Clinical case series of 15 patients with suspected orbital vascular lesions seen in the Neuro-ophthalmology clinic of the Wilmer Eye Institute. The techniques of standardized echography (combined use of a contact B-scan and standardized A-scan) were performed by an experienced echographer, and data obtained were compared with other available imaging modalities to determine appropriate management. Patients were monitored for improvement, stability, or worsening of symptoms and signs. RESULTS: Based on echographic data obtained, 6 patients underwent surgery, 9 were observed over a follow-up period of 0-14 (mean 3.3) years. All patients demonstrated improvement or remained stable, and no complications developed from misdiagnosis during subsequent follow-up. CONCLUSIONS: Orbital ultrasound provides reliable imaging parameters and can be used as the primary imaging modality when evaluating suspected orbital vascular lesions.
