AIM: To explore the influence factors of the mid-long-term postoperative eye position of patients with intermittent exotropia(IXT).

METHODS: Retrospective analysis was performed on the clinical data of 78 patients with intermittent exotropia admitted to the ophthalmology department of our hospital during 2017-01/2018-08. Data of patients with strabismus type,operation age, preoperative binocular vision function and the eye position of preoperative and postoperative day one were collected, to explore the influence factors of the mid-long-term postoperative eye position.

RESULTS: The result display that 47 cases(60%)had positive eye position in the mid-long-term after operation. There were 43 cases of insufficient collection type, 18 cases(42%)cured in eye position. The operation was successful in 26 of the 31 cases(84%)of basic type; 3 of 4(75%)divergence excess type were successful after operation. The results of univariate analysis showed that the difference of strabismus type and preoperative eye position between the two groups was statistically significant(P<0.05). Multivariate logistic regression analysis showed that type of strabismus(OR: 5.769, 95% CI: 1.790-18.595), was independent influencing factors of the eyes position in the mid-long-term after operation(P<0.05).

CONCLUSION:The strabismus type was independent predictors of the eyes position in the mid-long-term after operation, which should be paid more attention in clinical practice.
