Marfan Syndrome – Page 29 of 50

The OCT en face projection image above left appears completely normal in zones with and without the underlying lesion. The middle top image is a B-scan ultrasound at low sensitivity and the middle bottom is at high sensitivity and both are sections through the right eye lesion. In contrast, the B-scan above right is through the unaffected normal left eye at low sensitivity. Bone, calcium and metallic foreign bodies all reflect sound well, even at low sensitivities. The B-scan results strongly support the diagnosis of a flat bone lesion (white arrows) at the level of the choroid.
