What is the primary purpose of a diagnostic ophthalmic ultrasound?

The primary purpose of a diagnostic ophthalmic ultrasound is to evaluate the anatomy and conditions of the eye and surrounding structures. This imaging technique utilizes sound waves to create detailed images of ocular tissues, allowing for the assessment of various eye conditions such as tumors, retinal detachment, and other abnormalities.

Ophthalmic ultrasound is particularly valuable because it can visualize structures that may not be seen through other imaging modalities, especially in cases where the view of the eye is obstructed, such as with cataracts or vitreous hemorrhage. By obtaining clear images of the anterior and posterior segments of the eye, clinicians can make informed decisions about diagnosis and treatment.

In contrast, measuring intraocular pressure focuses specifically on detecting glaucoma but does not provide extensive anatomical details. Assessing visual acuity is a separate clinical evaluation that tests the function of the eye rather than its structure. Diagnosing systemic diseases, while important, does not fall within the primary scope of ophthalmic ultrasound, which is targeted towards ocular and orbital assessment.
