Septo-optic dysplasia (SOD) occurs in 1 in every 10,000 live births and encompasses more than just loss of eye sight. Symptoms include developmental delays, seizures, visual impairment, sleep disturbances, precocious puberty, obesity, insomnia, hearing loss, and cardiac anomalies. A growth hormone shot is normal for children with this disease, which can cause blindness in one or both eyes. There is currently no known cure. Prognosis varies depending on the person and the presence of symptoms. Common illnesses can be deadly to children with SOD. Families of children who have this disease spend several days in and out of hospitals.
