Abstract: very distinct subgroup, for they differ from cases of con- genital nystagmus with compensatory head shaking.2In the first place the wave form of congenital nystagmus usually consists of much lower frequency oscillations interrupted by saccade-like movements.In addition the compensatory type of head shaking in congenital nystagmus accompanies a modification of the nystagmus rather than a total sup- pression.'Perhaps the most distinctive difference sympto- matically is that visual acuity in congenital nystagmus is relatively preserved and enhanced during head shaking.In contrast, visual acuity in our patients with high frequency oscillatory nystagmus was markedly impaired.Alternatively, as we believed of the patient we reported, all 3 children may be examples of spasmus nutans.If this is so and the classical descriptions of spasmus nutans are com- prehensive, then they should eventually resolve.3Unfor-
