Diagnostic findings in infants with poor eye contact. Diagnostic findings for “normal” infants with/without idiopathic infantile nystagmus, including infants with isolated delayed visual maturation (group 1) are shown in green. Diagnostic findings for infants with a neurological abnormality (group 2) are shown in purple. Diagnostic findings for infants with an obvious structural ocular cause of poor vision (group 3) are shown in blue. Infants who were referred with a suspicion of poor vision but were found to have normal visual function at first examination are shown in yellow. None of the infants with idiopathic infantile nystagmus had structural ocular abnormalities
