  1. a“Distance” indicates exotropia at 6 m; “near” indicates exotropia at 0.33 m; the values are in prism diopters, mean; b“DE” indicates presumed pseudo-divergence excess type of recurrent exotropia which was not confirmed for the lack of occlusion test in recurrent exotropia; c“DE” indicates true-divergence excess type which persisted from primary exotropia to recurrent exotropia, CI convergence insufficiency, and DE divergence excess
