Do children with cat eye syndrome generally experience a decline in physical abilities as they reach adulthood?
After an extensive search of the resources available to us, we were unable to find evidence of a decline in physical abilities for people with cat eye syndrome as they age. One article described eleven patients with cat eye syndrome at various ages. Though several of them experienced delays in growth and development during childhood, no mention was made of a decline in abilities once they reached adulthood. In fact, one 20-year-old patient had muscle weakness that improved over time.

What is the long-term outlook for people with cat eye syndrome?
The long-term outlook (prognosis) for people with cat eye syndrome varies from person to person and largely depends on the severity of the condition and the associated signs and symptoms. Some babies who are very severely affected die during infancy; however, most people with cat eye syndrome do not have a shortened life expectancy.
