We reviewed the charts of 119 children with infantile esotropia followed for 27 months to 16 years (average 82.5 months). Of the 119, 14 (12%) had fine (high frequency, low amplitude) rotatory nystagmus. The presence of the nystagmus may account for a decline in visual acuity of up to two lines under binocular viewing conditions.
