Homocystinuria is an inherited disorder that keeps the body from processing the essential amino acid methionine. Osteopathia striata with cranial sclerosis is an X-linked dominant sclerosing bone dysplasia that presents in females with macrocephaly, cleft palate, mild learning disabilities, sclerosis of the long bones and skull, and longitudinal striations visible on radiographs of the long bones, pelvis, and scapulae (Jenkins et al. , 2009). Computed tomography (CT) was performed in 40 patients with a confirmed ophthalmic diagnosis and a change in the dimensions or configuration of the eyeball. The phenotype does Renal coloboma syndrome is characterized by hypodysplasia of the kidneys and optic never anomalies. Those closure anomalies leading to optic nerve colobomas involve the posterior portion of the embryonic fissure at the optic cup ( Chapter 13 ). A coloboma of the globe is a congenital anomaly that develops secondary to failure of embryonic fissure closure. A phenotypic classification is presented which may help the clinician to give a systematic description of the anomalies.
