B-scan ultrasonography is primarily used for what purpose?

B-scan ultrasonography is primarily utilized to provide a 2-dimensional image of intraocular structures. This imaging technique is particularly valuable in scenarios where direct visualization of the posterior segment of the eye is limited, such as in cases of cataract or vitreous hemorrhage. The B-scan offers a non-invasive way to visualize and evaluate the anatomy of the eye, including the lens, vitreous, retina, and optic nerve, helping clinicians identify various conditions such as tumors, retinal detachments, and other pathologies.

The significance of this capability lies in its ability to give clear diagnostic insights without requiring any invasive procedures, enhancing the decision-making process for further management or treatment of the patient’s eye condition.
