AIM:To analyze the eye position influence on far and near stereo vision of intermittent exotropia patients. METHODS:Far stereo vision was tested by Clement Clarke International synoptophore, using random-dot picture card.Near stereo vision was tested with three-dimensional map. Far and near stereo vision of 40 intermittent exotropia patients were measured preoperative and postoperative a week respectively, and the results were analyzed. RESULTS:Preoperative existence ratio of near stereo vision was higher than the rate of far stereo vision. Preoperative visual acuity distribution of near stereo vision was different from normal. Postoperative far and near stereo vision were improved in varying degrees. The difference was statistically significant. CONCLUSION:Intermittent exotropia patients have different degree far and near stereo vision. The stereo vision damage in intermittent patients shows the loss of far stereo vision and the decline of near stereoacuity.Most patients with intermittent exotropia have near stereo vision, but the stereoacuity is lower than normal. The operation of eye position correction is important for near stereoacuity improvement and far stereo vision reconstruction. Surgery timing for patients with intermittent exotropia should be referred to the distance and near stereoscopic vision test results.
