【摘要】：[目的]分析不同近视程度儿童的调节功能,探讨近视与调节之间的相关性。[方法]从2016年1月至2017年2月在昆明医科大学第一附属医院眼科门诊首次就诊的近视儿童中随机选取84例,进行调节功能的检查,包括调节反应、调节幅度、调节灵活度、相对调节。根据近视程度分为低、中、高度近视组,将各项检查结果与近视程度进行统计分析。所有数据经SPSS 21.0统计学软件处理比较。[结果]1、不同近视程度研究对象的性别分布:本研究中共入选84例,其中男性38例,所占比例为45. 23%;女性46例,所占比例为54. 76%。各近视程度组研究对象的性别构成差异经卡方检验无统计学意义,P=0.97。2、不同近视程度调节类型的分布:在本研究中,调节滞后共计55例,占65. 48%;调节等同共计19例,占22. 62%;调节超前共计10例,占11. 90%。低度近视组中调节滞后、调节等同、调节超前的发病率分别为64. 81%、22. 22%和12. 96%;中度近视组中调节滞后、调节等同、调节超前的发病率分别为65. 22%、26.09%和8. 70%;高度近视组中调节滞后、调节等同、调节超前的发病率分别为71. 43%、14. 29%和14. 29%。对不同近视程度组中调节滞后者进行统计分析,低度近视组与中度近视组、低度近视组与高度近视组比较存在统计学差异(P0.001),中度近视组与高度近视组比较无统计学差异(P=0.67)。3、不同近视程度的调节功能检查结果分布:相对调节中,各近视程度之间的正相对调节比较差异无统计学意义(P=0.12),各近视程度之间的负相对调节比较差异无统计学意义(P=0.99)。调节灵活度中,各近视程度之间比较差异均无统计学意义(P0.05),双眼(P=0.79)、右眼(P=0.80)、左眼(P=0.97)。同一近视程度组中双眼、右眼、左眼三组间两两比较差异无统计学意义(P0.05)。调节幅度中,低度近视组与中度近视组比较差异有统计学意义(P0.05)、中度近视组与高度近视组比较差异有统计学意义(P0.05)、低度近视组与高度近视组相比较差异有统计学意义(P0.001)。[结论]近视患者的调节功能表现为:1、调节滞后在近视患者中发病率较高,且表现为与低度近视和中度近视相关。调节滞后在早期近视的发展中存在一定作用。2、调节幅度在不同近视程度间有明显差异,随着近视程度的增加呈现上升趋势。调节幅度与近视的发展相关。3、相对调节及调节灵活度与近视发展无相关性。
[Abstract]:[objective] to analyze the regulatory function of children with different myopia, [methods] from January 2016 to February 2017, 84 children with myopia were randomly selected from the ophthalmological outpatient department of the first affiliated Hospital of Kunming Medical University. Including adjusting response, adjusting amplitude, adjusting flexibility, relative adjustment. According to the degree of myopia, it is divided into low, medium and high myopia groups. All the data were compared by SPSS 21.0 statistical software. [results] 1. The sex distribution of the subjects with different myopia degree: 84 cases were included in this study, 38 cases were male, The proportion was 45. 23; female 46, the proportion was 54. 76.There were no significant differences in sex composition among the subjects in each myopic degree group by chi-square test. The distribution of different types of adjustment of myopia: in this study, the adjustment lag was 55 cases. In the low myopia group, the adjustment lag, the adjustment is equivalent, the incidence of the adjustment leading is 64. 81%, 22. 22% and 12. 96 respectively; in the moderate myopia group, the adjustment lag, the adjustment is equal, the adjustment lag is equal, the adjustment is equal in the medium myopia group, the adjustment lag is the same in the moderate myopia group, the incidence of the adjustment leading is 64. 81%, 22. 22% and 12. 96% respectively; in the moderate myopia group, the adjustment lag is the same. The incidences of adjustment leading were 65. 22% and 8. 70%, respectively. In the high myopia group, the incidence of adjustment lag, adjustment equivalence, and adjustment leading were 71. 4343, 14. 29% and 14. 29 respectively. Statistical analysis was made on the patients with adjustment lag in different myopia groups. There was statistical difference between low myopia group and moderate myopia group, low myopia group and high myopia group. There was no statistical difference between moderate myopia group and high myopia group. There was no significant difference in positive relative regulation between different myopia degrees and there was no significant difference in negative relative regulation between different myopia degrees. There was no significant difference in the degree of myopia between the three groups (P0.05, P0. 79, P0. 80, P0. 97, P0. 97). There was no significant difference between the three groups in the same degree of myopia (P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05). There was significant difference between low myopia group and moderate myopia group. There was significant difference between moderate myopia group and high myopia group (P 0.05). There was significant difference between low myopia group and high myopia group (P 0.001). [conclusion]. The regulatory function of myopia patients was as follows: 1. The incidence of adjustment lag was higher in myopia patients. The results showed that it was associated with low myopia and moderate myopia. There was a certain role of regulating lag in the development of early myopia, and the amplitude of regulation was significantly different among different myopia degrees. With the increase of myopia degree, the amplitude of adjustment is related to the development of myopia. There is no correlation between relative adjustment and flexibility of adjustment and development of myopia.
