【摘要】：目的:利用改良OCT检测法研究屈光参差弱视儿童视网膜神经纤维层(RNFL)厚度。方法:随机选择未接受弱视治疗的4~14岁屈光参差性弱视儿童30例,取弱视眼为弱视组,非弱视眼为非弱视组;随机选取相同年龄50例正视儿童右眼作为正常对照组。利用光学相干断层扫描(OCT)测量患者视盘周围视网膜神经纤维层厚度,将所得三组数据利用Littmann公式修正,分别进行两两比较。结果:未校正和校正后三组间各部位RNFL厚度两两比较均无显著差异(P0.05);校正前颞侧、颞下、鼻侧、鼻下RNFL厚度与眼轴有显著相关(P0.05),而校正后仅颞侧及鼻下RNFL厚度与眼轴有显著相关(P0.05)。结论:屈光参差性弱视儿童弱视眼RNFL厚度并无显著变化,对RNFL厚度的研究需要消除眼轴长度形成的测量误差。
[Abstract]:Objective: the use of improved OCT detection method of anisometropic amblyopia of retinal nerve fiber layer (RNFL) thickness. Methods: 30 patients did not receive treatment of amblyopia 4~14 years anisometropic amblyopia in children, the amblyopic eye amblyopia group, non amblyopic eyes of non amblyopia group; randomly selected 50 cases of the same age children face the right eye as the normal control group. The use of optical coherence tomography (OCT) retinal nerve fiber layer thickness measurement around the optic disc, the data of the three groups using the modified Littmann equation, respectively, compared to 22. Results: no correction and correction between three groups after each part of the thickness of RNFL 22 showed no significant difference (P0.05) before correction; the temporal, temporal, nasal, nasal RNFL thickness and axial length were significantly correlated (P0.05), and only after correction of temporal and nasal RNFL thickness and axial length were significantly correlated (P0.05). Conclusion: anisometropic amblyopia in children is weak There is no significant change in the thickness of the eye RNFL. The study of the thickness of the RNFL needs to eliminate the measurement error of the axis length formation.
