FIGURE 12.

B-scan ultrasonography of unaffected and affected eyes in another patient with the Sturge-Weber syndrome. The normal right eye (top left) has an incompressible retinal-choroidal complex measuring 1.36 mm in thickness, but which is nearly twice as thick at 2.63 mm in the affected left eye (bottom left), and compresses easily to 1.55 mm by the application of simple digital pressure to the globe (bottom right).
