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.
The etiology of exotropia is unknown, but on a rudimentary level there is impaired ability to maintain fusion and alignment. In the case of sensory exotropia, the poor acuity of one eye is the cause of the inability to maintain alignment. Risk Factors[edit | edit source] General Pathology[edit | edit source] Intermittent exotropia, the most common type of exotropia, has a usual onset between infancy and 7 years of age. There is no specific refractive error associated with exotropia. Although there is no specific racial predilection, Asians with strabismus are more often exotropic when compared to other racial groups.
