Idiopathic Congenital Nystagmus

Idiopathic congenital nystagmus (ICN) is a condition characterized by involuntary, rapid eye movements in infants and children that can affect vision. It is known to affect approximately one in every 2,500 newborns. The exact cause is unknown, but ICN is believed to be related to an abnormality in the brain or the nerves that control eye movement. In some cases, ICN can be associated with other medical problems. ICN can cause decreased vision or even blindness, depending on the severity of the condition. Treatment is typically aimed at improving the ability to focus the eyes and can include glasses, medications, eye exercises, and surgical procedures. Early diagnosis and treatment are essential in achieving the best outcome for ICN.
