Bilateral congenital restriction of upward eye movement
L. Tychsen, R. K. Imes and W. F. Hoyt
Neurologic evaluation of a child with a severe headache revealed a
bilateral inability to move the eyes above the horizontal plane. Computed
tomographic and magnetic resonance scans of the brain obtained for a
suspected midbrain lesion were normal. Photographs from early childhood
confirmed that the deficit was congenital.
