Table 3.
The number (percentages) of the patients with each type of deviation and the mean and standard deviation of the horizontal and vertical deviations in the first visit and 1, 3, and 6 months visits. To calculate mean deviations, hypertropia and exotropia were used with positive signs, and hypotropia and esotropia were used with negative signs.
