摘要： 目的 ·分析并比较远视屈光参差性弱视儿童弱视眼与对侧非弱视眼的脉络膜层、黄斑神经节细胞复合体的厚度差异。方法 ·选取远视屈光参差性弱视儿童 63人，利用频域光学相干断层扫描图像增强技术（ enhanced depth imaging spectral-domain optical coherence tomography，EDI-OCT）分别检测双眼黄斑中心凹下脉络膜层厚度和黄斑区神经节细胞复合体厚度。同一受检者弱视眼与对侧非弱视眼的指标差异采用配对 t检验分析。结果 ·弱视眼黄斑中心凹下脉络膜层厚度为（ 321.83±12.74）μm，而非弱视眼的黄斑中心凹下脉络膜层厚度为（ 316.78±18.76）μm（P0.182）。弱视眼黄斑神经节细胞复合体的厚度为（ 83.78±4.81）μm，而非弱视眼的黄斑神经节细胞复合体的厚度为（ 83.26±4.17）μm（P0.223）。结论 ·远视屈光参差性弱视儿童的弱视眼与非弱视眼黄斑区脉络膜厚度与神经节细胞复合体厚度的差异无统计学意义。

Abstract:
Objective · To analyze and compare the subfoveal choroidal thickness and macular ganglion cell layer (MGCL) thickness in hyperopia anisometropic amblyopic children between the amblyopic eyes and the fellow eyes. Methods · The subfoveal choroidal thickness and the MGCL thickness were measuredenhanced depth imaging spectral-domain optical coherence tomography (EDI-OCT) in 63 hyperopic anisometropic amblyopic children. The value of subfoveal choroidal thickness and the MGCL thickness were compared between the amblyopic eyes and the fellow eyes. The average thickness of the eyes between the different types was compared using the paired t test. Results · Mean subfoveal choroidal thickness was (321.83±12.74) μm and (316.78±18.76) μm respectively in amblyopic and fellow eyes (P0.182). Mean MGCL thickness was (83.78±4.81) μm in amblyopic eyes and (83.26±4.17) μm in the fellow eyes (P0.223). Conclusion · Mean subfoveal choroidal thickness and MGCL thickness were not statistically significant between hyperopic anisometropic amblyopic eyes and normal fellow eyes.
