B-scan ultrasonography is an inexpensive, fast, and practical method to reliably diagnose numerous conditions and pathologies of the optic nerve. Most conditions diagnosed using ultrasonography locate to the optic nerve head and the anterior part of the optic nerve. It is an imaging method of choice for optic disc drusen, in which it is more sensitive than orbital CT and fundus photography (Fig. 6.1) . Optic disc edema and deep cupping can also be detected by ultrasonography (Figs. 6.2, 6.3, 6.4 and 6.5), but other modalities such as spectral optical coherence tomography are more accurate in quantitative analysis.
