Introduction of a new classification of poor visual contact

Group 1: Poor visual contact with or without nystagmus in a “normal” baby
 After clinical ophthalmological and electrophysiological investigation this group can be classified as follows:
 • congenital idiopathic nystagmus
 • underlying sensory defect
 • isolated delayed visual maturation
Group 2: Poor visual contact in a neurologically abnormal baby
Group 3: Poor visual contact with obvious structural ocular abnormalities
