目的对比研究增视能训练软件与笔尖训练对矫正飞行员小度数共同性外斜视集合能力的疗效。方法选取40例2015年6月—2016年6月在眼科体检时诊断为小度数共同性外斜视的现役飞行员,年龄均在25~45岁。随机分为2组(增视能训练组和笔尖训练组),且每组人数相同。2组的一般资料在年龄、视觉、身体素质等方面相比较均无统计学意义(P>0.05),可以进行比较。对40例现役飞行员进行同视机融合范围检查,并排除眼部其他器质性病变。并随机分成增视能训练组(n=20)与笔尖训练组(n=20)进行融合训练,增视能训练组采取智能化训练系统对受检者行集合功能训练,3次/d,10 min/次;笔尖训练组每天行笔尖训练3次,每次30回。分别使用同视机检查1、3、6个月融合范围的变化,并进行组内及组间对比。依据空勤人员和空中交通管制员体检合格证医学标准(CCAR-67FS-R2):12.5影响视功能的显斜视、隐斜视或眼球运动受限应评定为不合格。正常人辐辏平均为25°~30°,分开为4°~6°,垂直分开为2△~4△,旋转为15°~25°。结果 (1)增视能训练组:1、3、6个月集合范围较矫正前有显著提高(P<0.05)。(2)笔尖训练组:1个月集合范围较矫正前无明显提高(P>0.05),3、6个月较矫正前有显著提高(P<0.05)。(3)2组间比较:增视能组1、3、6个月集合范围显著高于笔尖训练组(P<0.05)。结论增视能训练软件及笔尖训练均对小度数外斜视集合能力的矫正疗效确切,且增视能软件较笔尖训练矫正集合能力更快更有效。本试验结果为现役飞行员提供了及时有效的训练方式,从而延长了飞行年限,进而保障飞行安全。同时针对小度数外斜视患者的矫正训练提供了指导意见,提高集合能力,促进其视功能水平的恢复。
Objective To compare the curative effect of augmented ability training software and nib training on correcting pilots’ ability of small degree common exotropia collection. Methods Forty active pilots who were diagnosed as minor exocrine exotropia at the time of eye examination from June 2015 to June 2016 were selected, all of whom were 25-45 years old. Randomly divided into 2 groups (visual acuity training group and nib training group), and the same number of each group. The general information of 2 groups had no statistical significance in terms of age, visual quality and physical fitness (P> 0.05), which could be compared. 40 active pilots were examined with the same scope of fusion, and exclude other organic eye lesions. (N = 20) were randomly divided into training group (n = 20) and training group (n = 20). The visual training group adopted the intelligent training system to train the subjects’ 10 min / time; tip training group nib training 3 times a day, each time 30 times. The changes of the fusion range at 1, 3 and 6 months were examined with the same machine, and intra-group and inter-group comparison. Based on the Medical Criteria for Airline Crew and Air Traffic Controller Medical Examination (CCAR-67FS-R2): 12.5 Obstructions of significant strabismus, phoria, or eye movement affecting visual function should be assessed as unacceptable. The normal person average 为 为 25 ° ~ 30 °, separated by 4 ° ~ 6 °, vertical separation of 2 △ ~ 4 △, rotation of 15 ° ~ 25 °. Results (1) Visual acuity training group: The collection range of 1,3,6 months was significantly higher than that before correction (P <0.05). (2) In the nib training group, the range of collection in one month was not significantly higher than that before correction (P> 0.05), and significantly increased at 3 and 6 months (P <0.05). (3) Comparison between the two groups: The range of collection of 1,3 and 6 months of increasing visual energy group was significantly higher than that of nib training group (P <0.05). Conclusions The visual acuity training software and the pen tip training both have a definite curative effect on the ability of small exotropia collection, and the visual acuity software is faster and more effective than the pen tip training to correct the ensemble ability. The results of this test provide timely and effective training methods for active pilots, thus extending the flight life and ensuring flight safety. At the same time, it provided guidance for corrective training of patients with small exotropia to improve the ability of assembly and promote the restoration of visual function.
