Contrast Agent and Molecular Imaging Meta-Analysis of the Clinical Effect of Intelligent Image Sensor Combined with Visual Training in the Treatment of Children with Intermittent Exotropia in China.

At present, the main treatment for strabismus is still surgical treatment, but there is no unified standard for the evaluation of the timing of surgery. This study mainly explores the clinical effects of using meta-analysis of intelligent image sensors combined with visual training to treat children with intermittent exotropia. Cochrane systematic reviews collect, evaluate, and synthesize an increasing number of original clinical research results to obtain the comprehensive effect of relevant interventions, so as to provide real and reliable evidence for health decision-making and clinical practice. It uses scientific, clear, and reproducible research methods to reduce the influence of biased factors, so it is different from traditional reviews. Cochrane systematic reviews are especially suitable for certain interventions when the pros and cons of interventions are difficult to determine based on the results of a single clinical study or when there are large differences in the clinical application process. Poor quality systematic reviews can mislead policymakers and clinicians. In the meta-analysis, the Cochrane systematic evaluation method of evidence-based medicine was used to comprehensively search the published literature research on the treatment of intermittent exotropia with vision training. Using the Cochrane system evaluation method, computer search of CENTRAL, MEDLINE, Embase, Chinese Biomedical Literature Database, Chinese Journal Full-text Database, manual retrieval of relevant conference documents, and inclusion of all clinical trial documents of visual training in children with intermittent exotropia was conducted. Patients with intermittent exotropia were selected, simultaneous vision, fusion function, and far stereo vision with the same vision machine were measured, and near stereo vision with a stereo vision chart was measured. The number of simultaneous vision, fusion function, and distance and near stereo vision "with" and "without" cases were recorded for all patients, and the relationship with age of onset, type of strabismus, degree of strabismus, and degree of control was counted. Among them, 91 patients who underwent strabismus correction surgery were followed up for at least 6 months with correct eye position. The presence or absence of simultaneous vision, fusion function, far stereo vision, and near stereo vision were recorded and compared with preoperative. The number of recovery and nonrecovery cases was recorded, and the relationship between the age of operation, the type of strabismus, the degree of strabismus, and the degree of control was counted. It was statistically analyzed by SPSS22.0. The results of the meta-analysis showed that in terms of the effective rate of fundus lesions, the visual training group was better than the nontraining group, and the difference between the two groups was statistically significant (RR = 1.32, 95% CI: (1.25, 1.40), P < 0.0001). This study provides guidance for the early rehabilitation of children with intermittent exotropia.

Effect of Applying Binocular Visual Training after Slanted Lateral Rectus Recession on Orthophoric Rate and Binocular Visual Function Recovery on Patients with Convergence Insufficiency-Type Intermittent Exotropia.

OBJECTIVE: To explore the effect of applying binocular visual training after slanted lateral rectus recession on orthophoric rate and binocular visual function recovery on patients with convergence insufficiency-type intermittent exotropia (CI-IXT). METHODS: A total of 76 CI-IXT child patients treated at the Strabismus and Pediatric Ophthalmology Department of our hospital from June 2019 to June 2020 were selected as the research objects, and those who met the inclusion criteria were equally divided into group A (63 eyes) and group B (61 eyes) according to the sealed envelope randomization. All child patients accepted the slanted lateral rectus recession, and after that, those in group A accepted the binocular visual training and those in group B accepted the conventional visual function rehabilitation training, so as to compare their position of eye, the best corrected visual acuity, etc., after training for statistical analysis. RESULTS: Compared with group B after one month of surgery, group A had significantly less patients with grade I binocular vision function (P < 0.001) and more patients with grade II and III vision function (P < 0.05); between group A and group B, after 3 months and 6 months of treatment, the number of eyes with normal stereoscopic vision was significantly higher in group A (P < 0.05); at 15 days, 1 month, 3 months, and 6 months of treatment, the visual strain scores of group A were significantly lower (P < 0.001); after treatment, the number of orthophoria eyes was significantly higher in group A (P < 0.001), while the numbers of overcorrected eyes and undercorrected eyes were significantly higher in group B (P < 0.001); and the total incidence rate of adverse reactions was significantly lower in group A (P < 0.05). CONCLUSION: Applying binocular visual training to child patients with CI-IXT after slanted lateral rectus recession can promote the recovery of binocular vision and ensure higher safety, and further study will help to establish a better solution for the affected children.
