Congenital nystagmus is that which exists from birth or soon after.
Acquired Nystagmus can appear later in life as a result of medications, head trauma, tumors, and a variety of other things. Most people searching for the meaning of Nystagmus though, are parents who probably noticed their child's unsteady gaze and dropped into the doctor to check out what they hoped was a minor problem. Some Nystagmus is normal for an infant, but when it persists past a certain point, it has become Nystagmus the condition. Nystagmus is not the result of something the parent did or failed to do. It can be hereditary but often isn't.
