Disease[edit | edit source] Exotropia is a type of eye misalignment, where one eye deviates outward. The deviation may be constant or intermittent, and the deviating eye may always be one eye or may alternate between the two eyes.
Divergence of the lines of vision of the two eyes. Divergent squint. In exotropia one eye points at the object of regard, the other is directed outwards. In exotropia acquired in adult life there is usually double vision (diplopia). In childhood, the false image may be suppressed and long-term visual acuity may be affected in one eye.
