Clinical efficacy observation of the operation therapy for intermittent exotropia

Objective To investigate the operation opportunity and long-term effect of operation on patients with intermittent exotropia.Methods The preoperative strabismus angle,fusion function and binocular vision function,and the postoperative eye position,fusion function and binocular vision function in 96 cases of intermittent exotropia were examined,and the effects of operation were observed.Results The final eye position of intermittent exotropia operation was not correlated with age of onset,operation age and type of strabismus,but was correlated with the operative quantity and preoperative binocular vision.Patients with postoperative fusion function and binocular vision function and young operation age had more stable eye position postoperatively.Conclusions The preoperative fusion function and binocular vision function of the patients with intermittent exotropia have effect on the postoperative eye positions.Operation in early period is in favor of the recovery of binocular vision.
