Retrospective analysis reveals fixation distance affects control in patients with intermittent exotropia, suggesting improved assessment methods.

Control deteriorated in patients with intermittent exotropia as fixation distance increased, particularly at 1 m.
Among 48 patients, 79% had favorable baseline control, but 57% showed deterioration at 1 m.
Analysis involved testing eye position at 6 fixation distances using Kushner's method for classification.
Findings support the need for assessing deviation control at multiple distances for better clinical understanding.

Takada et al. (2025) studied this question.
