AIM: To study eye position control ability in patients with different types of intermittent strabismus.

METHODS: Totally 146 patients with intermittent strabismus treated in our hospital from September 2013 to April 2015 were enrolled in the study. The patients were divided into three groups according to the different types of the patients with intermittent strabismus. Fifty-five patients who had been separated from the strong type were used as part of the strong group,the basic type of 48 cases as the basic group,44 cases of collection insufficiency patients were set up as collection insufficiency group. Visual function and postoperative eye correction of the three groups were analyzed.

RESULTS: There were no differences in visual function among the three groups before operation, and the visual function of the three groups were improved after operation, and there was no difference among the three groups(P>0.05).The positive rates were 83.3%,81.2% and 54.6% of the strong group, basic group and collection insufficiency group respectively. There was no difference between the strong group and basic group,(P>0.05).There were significant differences between the strong group, basic group with collection insufficiency group(P<0.05).

CONCLUSION: Operations for intermittent external strabismus is different according to different types. The prognosis of the strong group and basic group is good and the prognosis of collection insufficiency group is poor.
