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 |
