Is there a way to detect if an unborn child has nystagmus and spasmus nutans?
JUN 04, 2018
There are many different causes of nystagmus, most of which cannot be diagnosed prenatally, either by ultrasound or genetic testing, with a few exceptions. Nystagmus may be associated with any malformation of the brain, which could be determined by ultrasound. Spasmus nutans is a specific and rare form of nystagmus that is usually idiopathic (no obvious cause). However, rarely, a brain tumor involving the optic pathways may be present in utero and is associated with spasmus nutans. This would probably be diagnosed on prenatal ultrasound.
