Abstract:AIM: To investigate the status of stereoscopic reconstruction in adults with intermittent exotropia after surgery, and analyze related influencing factors.METHODS: A retrospective study was conducted among 196 adults with intermittent exotropia who were admitted to our hospital from January 2019 to January 2021. All patients underwent strabismus surgery, and their preoperative and postoperative data were collected.RESULTS: Near and distal stereo visual function was not found in all the included 196 patients before surgery. The reconstruction rates of near stereo visual function and distal stereo visual function were 52.6%(103/196)and 50.5%(99/196), respectively. There were significant differences in surgical age, age of onset, course of disease, and postoperative level of horizontal strabismus between patients with near stereoscopic reconstruction(103 cases)and those without reconstruction(93 cases; P<0.001). Multivariate Logistic regression analysis showed that age of onset, course of disease, and postoperative level of horizontal strabismus were factors influencing near stereo visual function reconstruction(P<0.05). The receiver operating characteristic(ROC)curve showed that the area under the curve(AUC)values of age of onset, course of disease and postoperative level of horizontal strabismus to predict near stereo visual function reconstruction were 0.757, 0.737 and 0.727, respectively(P<0.001). There were significant differences in surgical age, age of onset, course of disease, and postoperative level of horizontal strabismus between patients with distal stereoscopic reconstruction(99 cases)and those without reconstruction(97 cases; P<0.001). Multivariate Logistic regression analysis showed that age of onset and course of disease were factors influencing distal stereo visual function reconstruction(P<0.05). ROC curve showed that the AUC values of age of onset and course of disease to predict distal stereo visual function reconstruction were 0.672 and 0.821, respectively(P<0.001).CONCLUSION: Stereoscopic reconstruction in adults with intermittent exotropia after surgery is affected by many factors, such as age of onset and course of disease. The influencing factors of near stereo visual function reconstruction and distal stereo visual function reconstruction are different, which deserves attention.
