Ultrasonography contains a wide selection of clinical indications. For instance, when examining a patient with ocular discomfort or pain, clinicians will use ultrasound to ensure a diagnosis of inflammation, orbital myositis, or dacryoadenitis. Imaging is often used to identify retrobulbar tissue, as well as the extraocular muscles, in patients with symptoms and suspected soft tissue enlargement secondary to Graves’ disease. There are various forms of diseases that involve the orbit and therefore the discussion of those disorders are often organized in line with the etiology (e.g., infection, inflammation, neoplasm) or by anatomic location.
