A 7-month-old boy was referred for monocular nystagmus and failure to thrive. He was born at full term weighing 3.63 kg after a normal pregnancy, labor, and delivery. He grew appropriately until 3 months of age, after which his weight dropped from the 50th percentile to the fifth percentile in 2 months despite maintenance of a fairly adequate caloric intake. The patient had multiple episodes of emesis. Results of his gastrointestinal evaluation were normal. At 6 months of age, he developed a constant rapid nystagmus of the right eye.
