Eligibility
Inclusion criteria
Inclusion criteria: Eligible were all children aged three to eight years with a normal psychophysical development, and onset of esotropia before age 1 who visited one of the clinics during the study period.
Exclusion criteria
Exclusion criteria: Previous strabismus surgery, an angle of strabismus larger than 24° or smaller than 10°, any normal binocular vision, convergence excess with angle of strabismus at near fixation 1.5 times larger than the angle at distance, more than 1 line Logmar acuity difference between the two eyes, hypermetropia over 6 diopters or myopia over 3 diopters, up- or downshoot in (25°) adduction more than 8°, V-pattern (25° up and down gaze) over 8°, A-pattern (25° up and down gaze) over 5° and manifest vertical strabismus over 4°.
