Individuals have vision impairment due to several malformations in the eyes such as small eyeballs, blockage in the tear ducts or lacking eyes completely. "Facial" refers to the face; those affected can have several abnormalities in that region. These abnormalities include a cleft lip, a cleft palate which is an opening in the roof of the mouth, widely spaced eyes (hypertelorism), sharp corners of the mouth that point upward, a broad nose that can include a flattened tip, along with several deformations of both the external and middle ear structures.
