Congenital nystagmus?

Also called infantile nystagmus, congenital nystagmus is the term most often used to refer to the condition which is either present at birth or noticed in the first few weeks or months of life. Another type of nystagmus, called acquired nystagmus, can occur later in life as a result of various medical conditions. Acquired nystagmus and its effects are quite different from congenital nystagmus.
