Figure 1. Subject with CFEOM combined with Möbius syndrome. A: External photograph. Ptosis is present due to poor levator function; lower facial nerve weakness is present bilaterally, and is greater on the right. B: Photograph of subject attempting to smile. Note the weak contraction of the risorius muscle with subtle creasing and dimpling of skin on her lower face (arrow). The angles of the mouth are minimally elevated under the maximal forced smile.
