Abstract:
AIM: To investigate the role of visual perception training on the recovery of visual function at all levels and the improvement of perceptual eye position in children with intermittent exotropia(IXT).METHODS: Prospective clinical study. A total of 74 patients with IXT who received corrective surgery for strabismus in the Ophthalmology Department of the First People's Hospital of Lanzhou City from January to June 2022 were collected and followed up for 3mo. The patients were randomly divided into 2 groups at 1d after surgery: 35 patients in the training group received binocular visual perception training, and 39 patients in the control group did not receive visual training. The changes of visual function and perceived eye position at all levels were observed at 1d and 3mo after operation.RESULTS: There were 24 patients(69%)with simultaneous perception in the training group at 1d after surgery and 34 patients(97%)with recovered visual function at 3mo after surgery, which was significantly higher than 1d after surgery(P=0.002). Furthermore, there were 22 cases(56%)of fusion function in the control group at 3mo after surgery, 13 cases(33%)of far stereopsis, 20 cases(51%)of dynamic stereopsis and 17 cases(44%)of static fine stereopsis. In the training group, there were 31 cases(89%)of fusion function, 25 cases(71%)of far stereopsis, 30 cases(86%)of dynamic stereopsis and 27 cases(77%)of static fine stereopsis, which were significantly higher than those in the control group(all P<0.05). The degree of perceived eye displacement in the training group decreased more significantly than that in the control group(all P<0.05).CONCLUSION: Postoperative visual perceptual training in children with IXT can promote recovery of visual function at all levels, improve perceptual eye position and enhance the control of eye position at the perceptual level of the brain.
