Researchers associate intermittent exotropia with mental illness in early adulthood.
MedPage Today reported that, according to a study published in the June issue of Archives of Ophthalmology, children with intermittent exotropia, which is a form of strabismus in which the eyes deviate outward, may have a nearly threefold increased risk of developing mental illness by early adulthood.

For the study, researchers from the Mayo Clinic followed 183 patients who were diagnosed with intermittent exotropia, 118 of whom were female. The cohort, plus age- and sex-matched controls, was followed to a mean age of 21.9 years. The investigators found that overall, a psychiatric disorder, including depression or anxiety, was diagnosed in 97 (53 percent) of the 183 patients, compared with 55 (30.1 percent) of the controls. In fact, children with the ocular problem were 2.7 times more likely to develop a psychiatric disorder than were age- and sex-matched controls, with rates of psychiatric disorders being significantly higher in boys, for reasons that remain unclear, the authors said.
