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.
ABSTRACT
@#AIM:To investigate the effect of visual training on the reconstruction of visual function in children with intermittent exotropia. <p>METHODS: A total of 94 children with intermittent exotropia diagnosed in our hospital from August 2016 to January 2019 were selected and 94 eyes were affected. According to whether the postoperative visual training was divided into two groups, 47 patients(47 affected eyes)were not visually trained after operation and were included in the control group; 47 patients(47 affected eyes)were visually trained 2wk after operation and were included in the observation group. Follow-up for 6mo was performed to observe the recovery of visual function and eye position regression.<p>RESULTS: Six months after surgery, the proportion of children in the observation group with simultaneous visual function(89%), fusion function(85%)and stereoscopic function(40%)was significantly higher than that in the control group(53%, 47%, 19%), and the orthotopic rate of children in the observation group was significantly higher than that in the control group(91% <i>vs</i> 66%).<p>CONCLUSION: The binocular visual function training after intermittent exotropia in children can promote the recovery of binocular visual function and reduce the risk of postoperative eye position regression.
ABSTRACT
@#AIM: To investigate postoperative binocular visual function reconstruction in intermittent exotropia children with binocular visual training. <p>METHODS: The clinical data of 108 cases of intermittent exotropia children admitted to our hospital from April 2013 to April 2016 were retrospectively analyzed. Among them, 45 cases with binocular visual function training were included in the control group; the other 63 cases with TSJ-IV synoptophore training software for binocular vision training were included in the observation group. The binocular visual function reconstruction and eye position regression of the two groups were observed. <p>RESULTS: Baseline data of binocular visual function and strabismus in two groups had no significant difference before surgery(<i>P</i>>0.05). At 3mo after operation, the visual function of grade three in the observation group was significantly improved, and the proportion of simultaneous vision, visual fusion and stereopsis in the observation group were significantly higher than those in the control group(<i>P</i><0.05). The proportion of patients with macular stereopsis and foveal stereopsis in the observation group was significantly higher than that in the control group, and the proportion of patients without stereopsis in the observation group was significantly lower than that in the control group, and the difference was statistically significant between groups(<i>P</i><0.05). At 3mo after operation, the proportion of strabismus ≤30<sup>△</sup> in the observation group was significantly higher than that in the control group, with statistical significance(<i>P</i><0.05). In addition, the eye position regression rate of the observation group was significantly lower than that of the control group in the postoperative 1a follow-up, and there was significant difference between the two groups(<i>P</i><0.05). <p>CONCLUSION: The children with intermittent exotropia taking postoperative synoptophore training can promote binocular visual function reconstruction, ameliorate the degree of strabismus, and avoid postoperative eye recession.
