目的
2
探索一种新的小鼠光学离焦性近视 (LIM) 模型的构建方法,揭示其屈光度与眼生物学参数的变化。
方法
2
27只21日龄C57BL/6小鼠分为3组:LIM组、平光镜 (PL) 组和空白对照 (N) 组,比例为5:1:3。以右眼为干预眼,左眼作为自身对照。于实验开始前,干预后第1、2、3和4周,复方托吡卡胺散瞳后检影检测屈光度,光学相干断层扫描在体测量眼轴。各组内,左右眼进行配对
t
检验。3组间比较,采用Welch's ANOVA,差异有统计学意义时,采用Dunnett's T3法校正
P
值进行两两比较。
结果
2
离焦诱导2周,LIM组内干预眼屈光度比对侧眼向近视漂移约(-2.55±1.54) D(
t
=6.430,
P
<0.000 1), 伴眼轴较对侧增长约(0.051 ±0.024) mm(
t
=7.837,
P
<0.000 1);组间比较,LIM组屈光度较PL组或N组近视漂移的均值分别为-2.30 D (
P
=0.014),-2.55 D (
P
<0.000 1),LIM组眼轴较PL组或N组增长的均值分别为0.048 mm (
P
<
0.000 1)、0.047 mm (
P
<0.000 1)。随干预时间延长,近视漂移程度增加。
结论
2
本研究构建了一种基于搭扣设计的可拆卸式小鼠LIM模型并进行验证,通过2周诱导,屈光度显著向近视漂移,眼轴显著增长。该LIM模型搭建简易,可为近视研究的动物实验的模型构建提供参考。
Objective
2
To explore a new model for lens-induced myopia (LIM) in mice and describe the changes of diopter and ocular biological parameters.
Methods
2
Twenty-seven 21-day-old C57BL/6 mice were divided into three groups (ratio, 5:1:3): LIM group, plano lens (PL) group and normal control (N) group. The right eyes were intervened while the left eyes were left as control. The refraction was detected with retinoscopy after the pupils were dilated with compound topicamide and ocular axial length was measured by optical coherence tomography (OCT) in vivo at baseline and 1, 2, 3, and 4 weeks after the intervention. Paired
t
test was performed between left and right eyes within each group. Welch's ANOVA was used for comparison among the three groups. When the difference was statistically significant, the Dunnett's T3 was used to correct
P
value for pairwise comparison.
Results
2
After 2 weeks of defocus induction, the refraction of the intervened eye in LIM group shifted to myopia about (-2.55±1.54) D(
t
=6.430,
P
<0.000 1), and the ocular axial length (AL) increased about (0.051±0.024) mm(
t
=7.837,
P
<0.000 1). The difference of interocular change in refraction in LIM group compared with PL group and N group was -2.30 D (
P
=0.014) and -2.55 D (
P
<0.000 1), respectively. The difference of interocular change in AL in LIM group was 0.048 mm (
P
<
0.000 1) and 0.047 mm (
P
<
0.000 1) compared with that in PL group and N group, respectively. With the extension of intervention time, the degree of myopia drift increased.
Conclusion
2
In this study, a clasp-based and detachable LIM model was described and validated. After 2 weeks of intervention, the refraction shifted significantly toward myopia and the AL increased significantly. The LIM model is simple to construct and can provide a reference for the model construction of animal experiments in myopia research.
