AIM: To analysis of intermittent exotropia patients parting mechanism, the effects of position control.

METHODS: A total of 50 patients with intermittent exotropia underwent strabismus surgery treatment were selected in our hospital from Jun.2014 to Jul.2014 as the research object. On the basis of all patients according to the close and distant strabismus degree difference were divided into basic 24 cases(visual far and near vision angle of oblique angle of the basic equal or differ 15 delta)or less, separation type to 17 cases(depending on the far angle acuity nearly 15 delta squint angle), set less than 9 cases(near vision acuity visual far angle of squint angle 15 delta)three groups, the eye position control ability was compared between the four methods, which were 6m(as far), 33cm as the standard(visual), the outdoor visual standard, and the 1h covering test.

RESULTS: The basic model of intermittent exotropia patients at 6m mark, at 33cm, watching outdoor logo, 1h cover test of four kinds test results respectively(55.10±1.62),(45.32±1.21),(64.85±1.77),(68.33±1.66)PD, separation of a strength type test results for the intermittent exotropia patients(50.23±1.88),(67.46±1.17),(76.95±1.64),(78.15±1.56)PD, inadequate collection type test results for the intermittent exotropia patients(50.98±1.29),(33.48±1.40),(43.65±1.49),(54.64±1.12)PD, differences between groups with statistical significance(P<0.05).

CONCLUSION: Patients with intermittent exotropia parting to eye position control ability significantly influences relationship, determine the classification will help to improve the effects of strabismus surgery, which should be paid attention during clinical attention.
