Abstract:
AIM: To observe clinical outcomes of visual function training combined with surgical intervention in children with intermittent exotropia.METHODS: Retrospective study. A total of 100 pediatric patients with intermittent exotropia admitted to the Children's Hospital of Soochow University from January 2022 to December 2024 were selected and divided into two groups based on treatment modality. Both groups underwent intermittent exotropia correction surgery. The control group did not follow a visual rehabilitation program postoperatively, while the visual rehabilitation group did. The differences were compared between the two groups in preoperative and postoperative 12 wk results of perceptual eye position examinations, visual perception stereopsis function tests, multifocal visual evoked potential outcomes, Chinese version of the Child-International Quality of Life for Children with Strabismus(Child-IXTQ)scores, and strabismus angle.RESULTS: The baseline data of the two groups were comparable. Both groups showed reduced horizontal and vertical perceptual eye position deviation at 12 wk postoperatively compared to preoperative levels, with the visual group exhibiting lower values than the control group(all P<0.01). At 12 wk postoperatively, the number of children in the visual group who recovered fine and dynamic stereopsis increased compared to preoperative levels, and this number was higher than that in the control group(all P<0.05). There was no significant difference between the two groups in the number of children who recovered coarse stereopsis preoperatively and 12 wk postoperatively(all P>0.05). Both groups showed reduced latency for the first and second rings at 12 wk postoperatively compared to pre-surgery, with the visual group exhibiting lower latency than the control group(all P<0.01). There was no significant difference in latency for the third and fourth rings between pre-surgery and 12 wk postoperatively in either group(all P>0.05). Both groups showed increased Child-IXTQ scores at 12 wk postoperatively compared to preoperatively, with the visual group scoring higher than the control group(all P<0.05). Both groups exhibited reduced strabismus angles at 33 cm and 6 m at 12 wk postoperatively compared to preoperatively(all P<0.01), but the visual group showed no difference compared to the baseline group(all P>0.05).CONCLUSION: Combining visual function training with surgical intervention for intermittent exotropia can improve multifocal visual evoked potentials, promote visual function recovery, and enhance quality of life.
