AIM: To study explore the eye position and binocular visual function in infants and young children premature after strabismus surgery related factors.

METHODS: Ninety cases were selected in ophthalmology department of our hospital underwent external strabismus surgery. The clinical data was collected and follow up 1 year postoperatively. The factor affected eye position and binocular visual function after surgery were analyzed including before the age of onset, type of strabismus, operative age, age at diagnosis, surgery far stereo visual function, operation before the near stereopsis function after surgery, ocular and so on.

RESULTS: The types of strabismus and postoperative eye position positive rate and operation after far, binocular visual function recovery of closely related, the difference was statistically significant(P<0.05). Preoperative far stereo visual function and near stereo visual function affected postoperative distant stereoscopic vision function, and near stereoscopic visual function of main factors, the difference was statistically significant(P<0.05).

CONCLUSION: Infantile exotropia surgery preoperative far stereo visual function, near stereo visual function and the type of strabismus is main factors affected postoperative eye position and function. It can provide some treatment bases for postoperative recovery in children with eye position and binocular visual function.
