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 explore the application of 10g/L cyclopentolate chloride eye drops in children, and to compare the different effectiveness of cycloplegia between 10g/L cyclopentolate chloride and atropine in Chinese children.METHODS:A total of 236 eyes of 118 children aged 3~12 years old were enrolled in this study including 80 eyes of 40 children with myopia, 156 eyes of 78 children with hyperopia and 146 eyes of 73 children combined with astigmatism. 10g/L cyclopentolate chloride eye drops were used once per 5min for 3 times and refractive diopter was obtained 1h after the last drop of cyclopentolate. Three days after that, 10g/L atropine was then used 1 time per night for 1wk and optometry was performed again. The children were divided into 3 groups ( myopia, hyperopia and astigmatism group ) according to the refractive status, in which astigmatism was independent of the degree of separation of cylinder statistics. The results of retinoscope refraction were then compared between 10g/L cyclopentolate and 10g/L atropine. RESULTS:The refractive diopter was -2. 25±1. 31D after 10g/L cyclopentolate eye drops and -2. 23±1. 32D after 10g/L atropine in myopic group. The refractive diopter was 1. 35±1. 19D and 1. 38±2. 00D in astigmastic group. No significant difference was found in myopic group and astigmastic group (P= 0. 109, P= 0. 374). While in the hyperopic group, the refractive diopter was 3. 76±2. 4D after 10g/L cyclopentolate eye drops, which was lower than that after 10g/L atropine 4. 39±2. 6D (P=0. 000). CONCLUSION: The results of this study suggest that 10g/L cyclopentolate chloride eye drops can be used in myopia and astigmatism children, and 10g/L atropine should be used in hyperopia children.
